How to Remove Lime Scale

Lime scale is a chalky white mineral deposit (alkaline) which is a result of hard water. It often occurs on faucets and in tubs and appliances, such as kettles and coffeemakers and can leave silver and chrome with a gray dullness. White vinegar contains acetic acid and is a great place to start for cleaning these pesky stains. Over time, these mineral build-ups can damage sinks, toilets, and tubs and make soap scum harder to remove.

What You’ll Need

  • White vinegar
  • Rag or paper towel
  • Rubberband or hair clip
  • Baking soda
  • Water softener
  • Cream of tartar
  • Denture cleaning tablet (optional)
  • Lemon juice
  • Sponge or soft cloth
  • Borax
  • Toilet brush
  • White wine (optional)

The Cleaning Process

To clean faucets

Soak a rag or paper towel in vinegar and wrap around your faucet. Secure in place with a rubberband or hair clip. Let sit for an hour before wiping the faucet clean with a soft cloth. The Ultimate Accidental Housewife by Julie Edelman also suggests creating a paste with 3-parts baking soda to 1-part water. Apply the paste to the faucet, leave it on for an hour, and wipe it clean.

To clean kettles

Use 2-tbsp. of water softener in a full kettle of water and boil the solution for 2-3 minutes. Repeat if necessary and then rinse out the kettle with clean water. You can also fill your kettle with equal parts vinegar and water, bring the solution to a boil, and leave it overnight. Don’t forget to rinse it out in the morning!

To clean aluminum percolators

Never use bleach on aluminum appliances. Fill the percolator with water and add 1/4-c. cream of tartar. Run the appliance through for one cycle and then rinse well with hot water.

To clean coffeemakers

Fill the reservoir with water and 2-tbsp. water softener. Run the appliance through for one cycle and then again with clean water. Haley’s Cleaning Tips by Rosemary and Graham Haley also recommends filling it with white vinegar, running it through once, and then running it through twice with clean water. You may also fill with hot water and one regular denture cleaning tablet. Run it through once and once again with clean water.

To clean sinks and tubs

Spray with either vinegar or lemon juice. You may also use a paste of cream of tartar and water. Let sit for 30 minutes before scrubbing clean with a sponge or soft cloth. Check out our articles on “How to Clean a Shower” and “How to Clean a Shower Head” for more detailed information.

To clean toilets

Mix a solution of equal parts white vinegar and borax. Drain the toilet bowl and pour solution in. Leave it in for 2 hours before scrubbing clean with a toilet brush. You can also add 3-c. of undiluted white vinegar to your full toilet bowl and scrub it clean. Keep your toilet tank clean by adding 3-c. of undiluted vinegar to it, as well.

To clean windows and shower doors

Spraying white vinegar on your windows and shower doors can remove mineral stains left from hard water. You can use leftover white wine to remove lime scale from glass.

To clean a washing machine

Remove hard water stains from the inside of your washing machine by pouring in 1-gal. of white vinegar and running it on the hot water cycle without any clothes inside.

    To clean a shower head, remove the shower head and place it in a small dish. Pour white vinegar to cover the affected area.

    After one hour, brush the scale off with a soft brush (old toothbrush) and rinse with hot water.

  2. Valorie says:

    I agree with Lynn’s tip about the spray and walk away foaming-type products. I tried them all and I finally found a winner. My water spots were really severe and a friend told me about Bruce’s heavy duty brown, a paste that you wipe on and rinse off. Now the water just rolls off the glass instead of sticking to it. Ace Hardware has it and it’s only like five bucks.

    Where do I pour the 1 gallon of white vinegar?

  4. Cory says:

    I have also tried using a citrus-based product to clean my kettle (such as TANG). It works well, but not as good as vinegar.

    I live in an apartment and the exterior windows have been neglected for years. How can I get the water stains off my windows?

  8. Nat says:

    What’s leftover wine?

  9. Nathan says:

    I have just found out that a little bit of paint-thinner goes a long way as long as you wipe it clean immediately after applying it. This is the fastest and most effective method that I have found so far.

  10. Andy says:

    Can you buy bottles of leftover white wine, as we never have any at our place?

  11. DQ2 says:

    What about the rusty-looking scale stuff in the bottom of the toilet bowl? I used a pumice stick and got a lot of it off, followed by a flat-head screwdriver. But I can’t reach a lot of it.

  12. Anma says:

    OK, for toilet rust, empty the water in the bowl by flushing the toilet with the water to the refill tank off. You can get the remaining water out with a sponge, rag or bilge pump (I happen to have them around the house) then fill the refill the tank with full strength white vinegar and flush (with the water still off). Let soak over night. Brush and flush. If that doesn’t work you can try muriatic acid and do the same routine, except it should only take an hour or less. **WARNING** Muriatic acid is powerful stuff and will eat a hole in…well just about anything not glass or porcelain so be careful! And if you notice anything itching, stop what you are doing and rinse with water.

  13. Mamone says:

    This may be redundant, but have you looked to see whether there are small screen filters just inside the taps? They usually can be removed and soaked in vinegar to clean. I also use an old toothbrush on the screens. Hope that might help.

  14. Mary says:

    I have a black refrigerator where we get our water from the outside and the black water-catcher is white from the water. I have also tried Lime Away to no avail.

  15. Ruth says:

    We have long standing lime scale on the ceramic tile in our shower. Have tried CLR, but it doesn’t make a dent. Any other suggestions?

  16. Rini says:

    Does anyone know how to get rid of hard water stains on mirrors? I heard white vinegar works and I’m about to try it. I wonder though, do I have to let it sit or can I soak it in a Mr. Clean Magic Eraser Sponge and then wipe it off? Any tips would be appreciated!

  17. Trudy says:

    I have a white film on the inside of some of my glasses – the dishwasher doesn’t remove it at all! Any ideas?
    Also, what is the best thing to use to clean a dishwasher? I’ve used vinegar and other dishwasher cleaning products, and nothing works!

  18. Ben says:

    I can not find the undiluted white vinegar in Sacramento, CA.
    Where can I find it? What kind of stores sell it? Thanks!

  19. Barbara says:

    I have a hot tub with lime scale on it. Have removed some with Lime Away. Any suggestions on the more difficult stuff – would a paste work?

  20. Don says:

    Hi, We have a front load washing machine and the barrel is covered in a scale of sorts. How can I remove it without pulling the machine and barrel apart?

  21. Marji says:

    Smart and Final sell large bottles of white vinegar. “Undiluted white vinegar” is just what you’d find in any grocery store, Heinz being a major brand, but the large bottles are more economical for cleaning purposes.

  22. Bharath says:

    Hi all,
    I tried to clean scaling from the kettle by mixing 1:100 parts of floor cleaning acid: water. I poured this mix in the kettle and two minutes later, all the scaling disappeared.
    Be careful when you mix; if the concentration is more, it may effect the kettle forever.
    Thanks,
    Bharath

  23. Tony says:

    My car windows have very difficult water stains and I believe I can remove them with carbonate soda, lime, and vinegar. Do you know how to prepare this?

  24. Dar says:

    If you can find it, run a package of lemon-lime Kool-Aid through your dishwasher cycle (with no dishes). It will take most (if not all) of the hard water stains out of it.

  25. Margaret says:

    I have a major lime buildup on the outside of my stainless steel commercial ice maker. Any suggestions on what I can use to clean it? I have tried CLR, Scrubbing Bubbles, Lime Away, etc., but nothing has even begun to remove it. Any suggestions?

  26. Katie says:

    I use The Works chemical cleaner. You can get it at any Dollar store. There is no scrubbing and there is no eating holes in anything. My entire shower stall turns brown, so I had tried vinegar and all those little tricks, only to loose the battle. I use the works, then spray a little rain-x on the shower stall. The rain-x helps keep a film over the fiberglass stall so the gunk has nothing to stick to. Hope this helps.

  27. Tina says:

    Is it safe to use white wine vinegar on granite work surfaces (draining board) to remove limescale (a heavy build-up)? If so, will I need to dilute it, or use it neat?

  28. Bill says:

    Under “Cleaning Toilets” above, it says “mix equal parts of white vinegar and borax.” I am not sure what this means as vinegar is a liquid and borax is a powder. Does it mean one cup of vinegar to one cup of borax powder?

  29. Tally says:

    I’ve tried CLR, vinegar, and baking soda. The lime build-up won’t budge. Any real solutions? Please don’t tell me to soak it in vinegar; I believe I’ve tried every variation I read online.

  30. Michael says:

    Eh, just use vinegar and lemon juice.

  31. Allen says:

    I have used everything I can find with no results. It just laughed at vinegar. I placed the door on it’s side and covered with full 100% vinegar. The lime just laughed.

    Any Suggestions?

  32. Melanie says:

    Try using the vinegar again, but also scrub the soaked lime scale with a cloth scouring pad or scrub brush.

    Paulo,
    The “c.” is an abbreviation for “cups.” So, three cups.

  35. Mo says:

    I have white patches on my concrete drive and cannot remove them unless by power washing, which takes the concrete with it. What are they? Mold? Does anything remove them?

  36. Melanie says:

    Mo,
    The white patches are most likely efflorescence (salt deposits), which can be caused by the salt within the concrete mix or road salts. Although it was once thought to be caused by lime, according to the Masonry Institute of America, chemical analysis has proved otherwise.
    Scrubbing the stains with a dry brush could be sufficient for fresh salt stains. The goal is to remove as much salt from the concrete as possible, so try to clean it carefully. If you just brush the salt off, but it sits on another part of the drive or in the dirt immediately next to the drive, it could re-enter the concrete. Using a vacuum to grab the particles from brushing the stain might help.
    Acid washes, such as vinegar, are often recommended as treatments for cleaning efflorescence. Pour diluted white vinegar on the stains, scrub the stains with a sponge or scrub brush, rinse the area thoroughly and dry the concrete with a dry cloth, wet/dry vac or a layer of baking soda. The water will promote the return of the stains if the concrete is not dried quickly.
    The vinegar is used to to break down the salt (that hasn’t appeared yet) and therefore prevent future salt stains. You can treat the entire driveway with diluted vinegar, but you must rinse the vinegar from the concrete thoroughly as the lingering acid could damage the concrete.
    If the staining is caused by efflorescence, you can seal the driveway to limit water exposure to the concrete. However, water can still enter the concrete through the ground, so it is best to seal the concrete after several cleanings of the efflorescence. You could attempt to prompt the efflorescence (soak the driveway with water and wait), clean and repeat until the stains barely return.
    You are correct that it could be mold, however mold usually causes darker stains on concrete. Thankfully, the white vinegar will also work if the stains are mold; allow the stains to soak for 10-15 minutes and rinse the driveway with a garden hose.

  37. Wyn says:

    Does anybody know where I can find the chemical reactions involved in these processes?

  38. Melanie says:

    Nat and Andy,

    “Leftover wine” is stale wine. The reason leftover/stale wine can be used as a cleaner (and fresh wine can’t) is because of the air exposure time – when a bottle of wine is opened, the wine is exposed to the air and begins to oxidize (combine with oxygen). As it oxidizes, it will become more acidic and eventually turn into vinegar, often within a couple days. Ways that people use leftover wine (rather than pouring it down the drain since it now tastes stale/like vinegar) are usually as a substitute for vinegar, like for a salad dressing or as a cleaning solution. In other words, you wouldn’t go buy leftover wine; you would buy vinegar. But if you happen to have any leftover wine, this is a way to use it. If you have a neighbor who likes wine, they might have some on hand. Otherwise, you can drink a portion of a new bottle and wait a few days to make your own leftover wine.

  39. Tori says:

    Trudy -
    That happens when you need to add salt to your water softener. If you don’t have one, you probably need one. Everything will come beautifully clean when the softener has sufficient salt and has run through your system. You can add the vinegar as well to get them sparkling clean. The more you run the dishwasher without the softener/salt, the worse your dishes will get.

  44. Stacy says:

    To remove hard water deposits from the toilet, wear waterproof gloves and use a plastic scrubby square. I tried using a knife, which was effective, but it too easily scratched the porcelain. I used the scrubby on another area, got better results, and no visible scratches. You may also drain the water below the deposit by plunging to avoid any splashing.

  45. Antoinette says:

    I am so fed up. I have tried EVERYTHING on the windows in Palm Bay, FL where there is horrible well water. The water softener does not make the water right. My brand new dishwasher even has a white film on my dishes. The windows I have washed over eight times using everything, even muriatic acid. It just left more white film. I am so tired of cleaning to no avail. What do PROFESSIONALS use to get the white film and marks off of windows?

  46. Herb says:

    I live in San Diego, where we get our water from the Colorado River. This is excellent, life-giving water; a gift from the gods. However, it has a lot of dissolved solids from its passage through the canyons of the West. I installed a new glass shower two years ago, which has been used daily since it was installed. My son, the user, is very conscientious about squeegeeing every time, but it has built up a film, which I assumed was calcium or phosphate or some other kind of mineral build-up from the hard water.

    We were ready to take it out and replace it with a shower base and curtain. My wife and contractor were lobbying for a water softener. I am resisting this. I don’t want another machine to maintain and take up space.

    After reading all the comments and recommendations online, I decided to tackle it. I sprayed on pure, undiluted Heinz white vinegar, let it sit for ten minutes, then scrubbed it with one of those sponges with a plastic mesh [don't know the name], then re-wetted it with the white vinegar spray bottle, squeegeed it and dried it with paper towels.

    Then, I noticed that the paper towels seemed to smear something greasy around on the glass. AH! The light went on. This was not hard water deposits. It was soap buildup. One of the main ingredients of soaps is oil.

    I have had excellent results on my cars with an instant detailer, made by Speed Demon. I even use it on the chrome and windows, and find it is superior to Windex, Invisible Glass and similar products. So, decided to try it on my shower. EUREKA!!! It is THE ANSWER! My shower looks fantastic. My wife even is ecstatic about the way the shower looks.

    Maybe other brands of instant detailer will work as well, but I have had such excellent results with Speed Demon, that is what I used. Speed Demon is available at Pep Boys, not my favorite store, but, hey, they have it. I love this stuff.

  47. Carrie says:

    We are noticing that our clothes, particularly black ones, come out of the wash looking a bit scummy. However, we have determined that it is not actually our detergent (used other washers). We’re wondering if we are getting mineral deposits on our clothes. Would simply cleaning the washer be effective, or should we also be adding something to our wash water besides our detergent?

  48. Iphie says:

    Hi, can I also use the vinegar to remove lime build-up in my hot water flask? If yes, how do I go about it? Thank you.

  49. Melanie says:

    Iphie,
    Yes, vinegar can remove lime build-up from a variety of items. To clean the flask, use the information in this article: How to Clean a Flask.
