CLEAN-ACT™ BIO-CLEAN is the “green” way to meet today’s stringent and ecologically responsible concrete, masonry and many natural and architectural stone cleaning needs. CLEAN-ACT™ BIO-CLEAN is designed to safely remove the most stubborn stains caused by oils, greases, dirt, and chemical residues that are common in new and existing construction cleaning.  Rather than using harsh acids or alkali, CLEAN-ACT™ BIO-CLEAN is made from surfactants and non-hazardous ingredients specifically selected for their environmentally friendly characteristics.
