When totally soaked with water, down comforters can be very heavy. The first thing you need to do then is to take into account the capacity of your home washer. This will avoid the risk of damaging both the comforter and the machine. You then observe these easy to follow steps on how to wash down comforter properly. Make sure that when you load a down comforter into the washing machine, see to it that you do not need to force it inside. The reason is that it is certain to be within the capacity of the washing machine if you don't have to do such. Use a minimal amount of soap or detergent since too much amount will damage the downs. Run twice the rinse process in order that the down comforter will be totally washed and the remaining detergents removed. Don't set the drying temperature at a high level or you will risk burning your down comforter. Better put it at a low level even if it means taking longer time to dry off. One useful method to follow is to put tennis balls inside the machine during the drying to fluff the down comforter and avoid clumping. If the down comforter remains damp, repeat the drying cycle or better yet get it out and hang it to dry under the sun.
