How to clean your yoga mat ....

Mix one part water with one part laundry detergent or dishwashing liquid in a spray bottle. spray the mat, and wipe it down with a damp cloth or paper towels. Rinse in the shower and hang to air dry.

For serious cleaning, fill your bathtub with warm water and add a little laundry detergent. Allow to soak for a while, and rub with a sponge. Rinse thoroughly. Place the mat on a towel, and roll up to squeeze out excess water then hang to air dry.

Or the lazy way --- just throw the mat in the washing machine, warm water, add a small amount of detergent (no bleach) and let the machine do the work. Hang to air dry.

Dont use super hot water to wash the mat -- you could lose some of the stickiness. You dont need all those fancy "mat cleansers" -- laundry detergent works fine. I use dish washing detergent half the time. It works for me.
