Bests & Worsts Reviews from Amazon

To be honest, the most valuable thing in this package is the brush. I tried the pen on our white tile floors in a test spot, and not only did I have to take painstaking care to stay in the lines, the paint came out unevenly and just looked weird. Save yourself the money and just do what I eventually did: mix 1/2 cup baking soda, 1/3 cup hydrogen peroxide, and 2 tsp dish soap (MUCH easier/faster to apply to the grout than the pen), let sit for an hour, use a toothbrush for a quick scrub, and wipe off. Results in the photo are from that DIY method!
