Joanne asked: How do I remove cola stains from an epoxy-coated garage floor? We applied an epoxy coating to our garage floor a few months ago. Soda leaked from one of the trash cans onto the floor and left a stain. I have tried bleach and baking soda, but the stain is still there. Any suggestions?
Cola stains are hard to remove in general. When they won’t come off of a hard surface, such as a floor, with normal cleaning, it provides a real challenge. Fortunately, epoxy floors can tolerate most cleaning products, which will help make this stain removal a success.
You Will Need:
- Cleaning product (choose one):
- Simple Green
- Concrete floor degreaser
- All purpose cleaners
- Shampoo (yes – it has worked!)
- Shaving cream
- Old towels
- Scrub brush
Steps to Remove the Cola Stain:
- Once you have selected a cleaning product, apply it generously to the surface of the stain.
- Allow it to set for several minutes, so that it can fully penetrate the stain.
- Next, use the scrub brush to scrub the area. If the stain is large or especially difficult, utilize a motorized scrub brush to make the job easier.
- Rinse with water.
- If some of the stain remains, repeat application, soaking and scrubbing. It may be useful to try different cleaning products to find the one that will work best for your particular stain.
- Once the stain is gone and the area is rinsed, dry with a towel.
Additional Tips and Advice
- Citrus cleaners are effective stain treatments, but they may begin to strip the epoxy coating if left on too long.
- Any all-purpose cleaner can be used. There are heavy-duty garage floor degreasers that can be used as well. These cleaning products can be found in hardware and home improvement stores. Look in the paint department.
- If the stain cannot be removed, it may have penetrated the epoxy coating and actually be underneath it. If this is the case, it will be necessary to strip the area, clean the stain and reapply the coating.
