I'm trying to get a contract with a major gas company here in Canada for doing their individual stations. I want to wash the concrete where the pumps are, or at least clean them of gas and diesel stains. What is the best way to clean them? Would it be hot water and a recapturing system put into place? Or is there a waterless system such as soda blasting that I can use for cleaning up grease, gas stains and diesel spots? It's pretty much illegal to wash it without recapturing it. What can you suggest and is there someone I can talk to up here in Canada? The person whom I spoke to is interested in a waterless system if I can use it.
Thanks Bill W.
