Washing a sleeping bag is almost as easy as washing everything else, but it is not recommended to do it too often. Wash your sleeping bag if it is visibly dirty, smells bad, or it has lost its "fluffy" effect.
How to wash your fiber bag
You can wash your bag at 40 degrees and low spin, Use Toko Eco Wash Universal Textile detergent, or other detergents made for sleeping bags so that there is no residue of the detergent in the filling.

How to wash your down sleeping bag
Wash the down bag in the washing machine with down washing and turn out all excess water when it has finished washing. Use 40-degree gentle wash, and use approx. 30% of the normal amount of detergent. The minimum capacity of the washing machine must be 7kg. Remember to close all zippers when washing. The best way to dry it is in a dryer on low heat. Use tennis balls or wash balls to restore elasticity and fluff. If you follow the washing instructions for your bag, the down will regain its carrying capacity well after washing.
A dirty sleeping bag can lose its effect ...
This especially applies to down sleeping bags. If you sweat a lot, or there is body oil, sunscreen, or fat on the down, they lose their ability to retain heat optimally. If you are on a long trip, it may therefore be a good idea to have a clean "sleeping outfit" that you do not get sweat or sunscreen on during the day, which is then taken down in the bag.
