Krud Cutter also works well. Spray on, wait about a minute, stuff brush 3-4 swipes, and wipe off with a clean rag. You'll need a lot of rags since wiping off with a dirty rag isn't very effective.

Krud Cutter looks like a cleaner, where as the Grout Refresh product is a stain/colorant and sealer that matches the Mapei grout color product line.

KC sounds like a great step 1 to clean, with Grout Refresh (or Custom Building Products’ version) being step 2 for getting the color where you want it.

You're right, it is. I have used the Mapei stuff and am not super impressed with it. Adhesion was very good and it has held up for the last 2 years, but it looks like a bit like paint to me. Applying it took absolutely forever too. I would only use it again if I had some exceptionally super nasty stained grout that I couldn't stand.

Thanks for sharing your observations. I’m happy to hear that it’s held up well (my primary concern). I do like the appearance because I have a relatively thin 1/8” grout line and I used their Ultracolor FA (fine aggregate) which to me looks nice without the coarse sanded grout (do not like that appearance).
