A sleeping bag will eventually need a cleaning. How do you proceed, in particular according to the different materials?

Are we talking in terms of cleaning gunk from the inside / outside, removing any smells from sweat etc. that may have built up, or just generally (combination of everything?) –  berry120 Jun 1 '12 at 23:39
    
@berry120: technically all, but my question is more about a full, deep cleaning. –  Stefano Borini Jun 1 '12 at 23:40

Please specify synthetic or down :) –  Russell Steen Jun 2 '12 at 2:17

The procedure is roughly the same for both Down and Synthetic, however down requires special precautions:

  • Never dryclean.
  • Wash by hand in a bathtub, or use a front-loading washing machine on gentle cycle. Down bags have thin baffles inside that keep the feathers partitioned. Agitators will put enough stress on the bag you risk tearing those baffles resulting in the dreaded clump.
  • Use non-detergent, no-perfume, non-bleach soap such as Nikwax designed for washing down. (There are common non-detergent laundry soaps as well). Down is a natural organic material, and hard detergents / bleaches can damage it.
  • When drying, use low heat (or no heat) on gentle cycle, and toss in a couple of tennis balls. The balls add some extra non-destructive ooomph to the process that helps break up clumps of down. Check regularly and pull apart any down clumps by hand you encounter.

Sadly, despite being as careful as possible, washed down almost never seems to be as good as new. So do it only when necessary - if ever. Smelly bags can often improve just by laying out in the sun for a few hours. UV is brutal on funk-bugs.

PROTIP: Using a sleeping bag liner (silk or other) that will intercept your body's dirt and oils (the down-killers) will extend the life or your bag.

First of all, check the label for directions.

I have a synthetic bag. I take it to the laundromat and wash it in a sufficiently large front-load machine, using cold water and somewhat less detergent than a normal load. I put it in a large dryer set to low or no heat until it seems mostly dry. Then I hang it up indoors for a day or two to finish drying. This seems to be pretty effective.
