Rest assured that our cleaners, strippers, and removers will do no harm to your masonry, no harm to the environment, and no harm to you.
Next To No Acids!
We believe that cleaning masonry with acid does more harm than good. Acids are difficult to work with; they're bad for the environment; and they eat away at the masonry. Most of our products contain no acid at all and our Heavy Duty Cleaner only contains as much acid as a single lemon - that's it!
Imagine Paint Removers that are biodegradable and non-toxic.
