Breaking in your Manduka PRO® mat is a beautiful thing.

The best way to break in your mat is practice, practice, practice, but if you want to speed things up a little, try a simple salt scrub. Generously sprinkle coarse sea salt on the mat and let it sit or scrub in a circular motion—like you would wax a surfboard. After 24 hours, wipe the salt off with a damp cloth. Repeat 2-3 times with fresh salt as needed.
