Cleaning bathroom grout gets a bad wrap.
According to the Good Housekeeping Institute removing the grime takes "less effort than you'd think".
All you need is a toothbrush, some bi-carb soda and vinegar. Simply mix the bi-carb with a little bit of water to form a paste. Using the toothbrush, wipe the grout with your mixture. Once, you’ve given the area a good scrub, fill a spray bottle with vinegar and spray the bi-carb. Scrub again with the toothbrush and rinse well when finished.
Additionally, for stubborn grout stains that won’t budge, there’s one more option worth trying: a grout pen.
While it won’t remove the grime, it will restore your stained grout lines to their former colour - or better yet, revamp them with a new one.
Once you have scrubbed your grout, use the grout pen to draw over the lines.
