Hi guys,Thank you for your input for yesterday's granite sinks. We did the job and the customer was very happy with the repair. I will post pics on that thread as soon as I get them.Today I have another question. We inherited a high traffic ceramic floor where the customer has been using a very strong, ph13, butyl based degreaser straight to get the floor clean. Although it gets it clean with agitation of a blue scrubbing pad, it doesn't stay clean long. I suspect damage to the surface. It should not require that chemical to be used straight and have aggressive agitation so often. Is it possible that micro scratches have created a scratch pattern that is rapidly trapping soils. This is in a movie theatre so the traffic is high but light duty. What do you guys think?PresidentMobile: 309.251.3192Visit list archives, subscribe, unsubscribe or change your subscription preferences: http://stoneandtilepros.simplelists.com/sccpartners Start a new conversation (thread): sccpartners@stoneandtilepros.simplelists.com
