free-wiping

Using the left hand to clean oneself, also known as "free-wiping," is a traditional practice in some cultures, particularly in regions where water is the primary cleaning method. It is important to wash hands thoroughly with soap and water afterward to maintain hygiene.

There are potential benefits to this practice, such as reducing paper waste and costs and putting less strain on sewage treatment plants.

During the pandemic, my girlfriend and I ran out of toilet paper, so we had to resort to free-wiping. :(
