Cleaning and maintaining your sleeping bag

The best way to look after your sleeping bag depends on its filling.

For polyester wadding, the procedure is as follows: 

place the sleeping bag in the washing-machine. Add a couple of tennis balls (new, or bleached when possible). They will pound the sleeping bag, thus resulting in more effective cleaning, without damaging it. Use a 30°, no-spin cycle. Then air dry the bag.

For down, the golden rule is to wash the sleeping bag as little as possible. The safest solution is to have it cleaned by professional dry-cleaners.

It is especially important to check that it is thoroughly dry, especially at the seams. You can help keep it clean by using a cotton or silk sleeping bag liner inside.
