I know that acetone won't damage it. When my Cambria was installed, it was cleaned with acetone. Don't know about the other stuff. Sorry.

A brief exposure to acetone won't damage quartz. Prolonged exposure will soften the resin material and cause it to partially dissolve and look "etched" and cloudy. Epoxy will be difficult to remove, as it will bond with the resin then you'd need an expert to remove it and not damage it further.

Overall, the best surface for a hobby area is a cheap sacrificial piece of plywood that you poly, i.e. a traditional worktop that you would see in any production shop. Use some wood edging attached to the top to be able to lay it over whatever "pretty" top you want to put underneath it. It's endlessly renewable at a very cheap cost when it inevitably becomes damaged.

Thank you. As always, I so appreciate the imformation I glean here.

We had some glue on our new Cambria countertops when the installers were done -- and they used acetone to remove it. It came off quickly but I'm worried that it will damage the countertop. The installer said no, but I don't trust him. Thoughts?

Oldryder above is a fabricator, and we trust him.

If it was damaged by the acetone, you'd see a dull spot. In Cambria's instructions to installers, it says to clean up using denatured alcohol. You can go to their PDF and show it to your fabricator. Maybe at one time acetone was okay.

Cambria constantly changes their use and care (and warranty) and now says homeowners can only clean it with soap and water, so maybe he was unaware they changed fabricator clean-up too.
