Whats the best way to whiten tile grout without using a grout pen?
Question: My grout was discolored (a sort of reddish brown), but does not work any mold in it. I used grout pens before, but they always seem to end the half paint and tiles. Any suggestions or products that can work justice?
Answer: Whiten and a toothbrush or nail brush and lots of elbow grease!
