Most concrete will clean-up without the use of chemicals. The exceptions would be heavy tree sap, oil and grease deposits. If needed we use a biodegradeable cleaner to get these deposits off. Heavy oil stains will leave some ares with a shadow of the former stain that will wear off over time. Our pocess removes all surface contaminates including dirt, mold, sap, tire marks and gum leaving your concrete clean and bright.
