Wash, don't wipe.
The campaign against dirty butts
Wash,
don't wipe.After the bathroom, you wash your hands — because smearing them with dry paper and calling it a day would be revolting. Your butt, the actual scene of the incident, gets exactly that treatment. Half the planet fixed this with a $25 water sprayer. This website exists to fix the other half.

Walk through it with us
1. 1 Something unspeakable happens in the bathroom. No judgment. Happens to everyone, roughly daily. 2. 2 You wash your hands with soap and running water. Obviously. You're not an animal. 3. 3 The actual site of the incident? A quick scrape with dry paper. Case closed, apparently. 4. 4
We think step 3 is insane. So does most of Asia, the Middle East, and anyone who's ever owned a bum gun. Read the full case — or skip ahead and buy the $25 fix.
