When I first wrote this post, I suggested purchasing an electric toothbrush to use as a grout cleaner in your bathroom. If it's good enough for your pearly whites, it is good enough for that finger and wrist aching work.
Then, by chance - was it really? - I spotted this nifty "bathroom-specific" scrubber at a yard sale.
Some of those toothbrush/toothpaste commercials sure make it look like we have to clean the grout between our teeth… 🙂
LOL!
