Bill, Mongo, anyone - grout on tile....
We've installed lovely penny round tiles in the guest bathroom in the basement and they look very nice. I decided I didn't like the white grout so I've stained it. Looks terrific. But there are several spots on the glossy penny round where grout was left, stuck on. Now it's showing like crazy of course since it's gray!
How can I get this off? Is there a solution I can use to help dissolve it? Do I need to scrape it off? And if so, what would be the best tool for this to minimize scratching the tile itself?
This was a DIY job and my DH, who is usually very good at this, had a hell of a time with the penny round. Anyway, we need to fix it. Welcome any advice before I start scraping.
