When we redid our guest bathroom I used white grout. It wasn’t as white as I wanted it to be though and started to look kinda dingy even after cleaning it. Luckily, during a trip to Lowe’s I found this stuff called Grout Refresh so we figured we’d give it a try.
Step 4: mist with water, wipe the excess Grout Refresh off the tile and enjoy your pretty white grout 🙂
I didn’t get an after picture but it looks awesome. Best part of the deal is that it is a colorant and a sealant!
