STAIN-PROOF® Acidic Cleaner, formerly known as EFF-ERAYZA™, is a new technology acid cleaner for removing efflorescence, rust stains, limescale, grout haze, mortar mess and fireplace soot. Acidic Cleaner is very powerful and generally more effective to use than traditional industrial acids but does not produce noxious fumes, non-corrosive to metals (except for uncoated aluminium) and temporary contact does not burn skin.
How To Use
- TEST PRODUCT ON A SMALL AREA TO CHECK ACID SENSITIVITY BEFORE FULL APPLICATION.
- If satisfied with test results, first sweep or vacuum all loose dust and dirt from the surface.
- Apply when surface temperature is between 40 – 95 °F (5 – 35 °C). Pre-wet surface with water.
- Pour, brush or spray mixed solution generously onto wetted surface and leave for up to 3 minutes.
- Do not allow solution to dry on surface. Clean large areas in sections.
- Rub with a white nylon scrub pad, or similar, to clean the surface.
- Always neutralize the acid by dissolving 1 cup of STAIN-PROOF™ Alkaline Cleaner (or other pH base/alkaline cleaner) into a bucket of fresh water and pour it over the surface. Let it sit for approximately 3 minutes.
- Rinse surface thoroughly several times with clean water using a mop or wet vacuum
