David asked: How do I clean plasterboard (gypsum) scuff marks on brick patio. I had builders use the brickwork patio to store and cut plasterboard sheets. I now notice scuff marks left by the plasterboard which water and scrubbing will not remove. Any ideas?
Muratic acid is the go-to solution for cleaning brick and concrete, but with a light job like removing scuff marks you should have great success with this more eco-friendly alternative.
You Will Need:
- Green Envy Muriatic Acid Replacement
- Soft bristle brush
- Rubber gloves
- Eye protection
Steps to Remove the Scuff Marks:
- Begin by protecting yourself with eye protection and quality rubber gloves.
- Following label directions, apply Green Envy Muratic Acid Replacement directly to the gypsum scuff marks.
- Scrub with a soft bristle brush to loosen and remove the scuff marks.
- Rinse the area completely with clean water. It may be helpful to scrub some more as you rinse to help remove the loosened residue.
- Repeat as needed until all of the residue is removed. It may be necessary to allow the area to dry in between cleanings. If there is residue remaining, it will be more noticeable once the area has dried.
Additional Tips and Advice
- Use eye protection and wear rubber gloves when working with muriatic acid. Read and follow all label directions and precautions for handling, storage and disposal.
- Green Envy Muriatic Acid Replacement is a cleaning product that has nearly the same cleaning power as muriatic acid with less fumes and zero VOC, making it more economically friendly. However, it still requires precautionary measures, and the eye protection and gloves should not be ignored.
- If the Green Envy does not remove the scuff marks, it may be necessary to use regular muriatic acid. Be sure to follow all label precautions.
