The following lists our concrete cleaners in strength order, from the most gentle to the most aggressive.

SAND BLAST

The gentlest product in our range. Dissolves concrete residue over 15-30 minutes. Safe to use on unpainted metal, including aluminium. Contains no harsh acids. Does not smoke or fume. Neutralisation not required.

CRETE D'SOLVE

Our “safest” fast-acting product. Will quickly chew though about 1/8” of concrete. No fumes, doesn’t usually burn, doesn’t immediately rust gear. After use, we HIGHLY recommend applying a high pH soap (such as Xtreme Clean or Xhaust & Soot Remover) to clean and neutralize the remaining acid

POWERHOUSE 50

Our most popular concrete remover. Same cleaning capacity as the Knockout without aggressive fumes and smell, and it’s much easier on the equipment. After use, we HIGHLY recommend applying a high pH soap (such as Xtreme Clean or Xhaust & Soot Remover) to clean and neutralize the remaining acid

KNOCKOUT 100

Knockout 100 is our “no holds barred” cleaner. It easily chews through ¼” or more of concrete. But this one does give off fumes, will burn and will rust bare metal if not properly neutralised. After use, we HIGHLY recommend applying a high pH soap (such as Xtreme Clean or Xhaust & Soot Remover) to clean and neutralize the remaining acid
