I wish I had this tool many years ago, there are always skinny little places that even a toothbrush can’t fit. This thing is perfect where the shower doors meet, around faucets at the sink, or anywhere that your other tools just don’t fit. It’s not super stiff so it works really well.


I’ve been trying to clean between my shower door overlap area for years. A toothbrush wouldn’t go all the way but this little gem is perfect for that.


Great for cleaning the tracks of sliding glass and screen doors.

    Thanks for these! Literally 2 minutes ago I was trying to clean the grime out of the plastic gasket on the washing machine thinking I need to find a way to for-real clean that gunk out! And BOOM – here’s H2S to the rescue!!
