I did the bottom of the four walls where there was water damage. It's a big shower and only the bottom of the shower had rotting grout.

I still don't know what it looks like for sure because it has a hazy layer on it and I can't clean it for another 2 days-as I just recaulked the bottom today.

When it's wet, it's the right colour-so hopefully when I clean it, it will look more gray.
