Hello Folks

Have been asked to bid on a hotel entrance and driveway. The surface is made up of clay tiles that are dark in color and madde to look like bricks. They have a good penetrating sealer on them now but there is quite a bit of oxidation sitting at the surface. What can I use to remove the oxidation and grime without damaging the sealer?

Thanks for the advice

Cleaner?

Thanks Bill. It looks like I will have to use an acidic based cleaner (HF) to get at the oxidation and grime. Will the sealer still hold up?

Thanks for posting
