It is certainly a possibility to wash a bed comforter in your washer at home, but there are a few things that you should check before you throw it in there. First, check to see if the comforter will actually fit into the washing machine. If your comforter is too big, and will not fit inside the washing machine, then of course you will need to take it to a laundromat or a cleaning service to have it cleaned. In order to determine if the comforter is too big for the washing machine, even though you can stuff at all inside, make sure there is enough room for the comforter to still move around when the tub is agitating and tumbling. The second thing you’ll want to check is the tag on your comforter to make sure that the label says it is machine washable. The tag will probably say that it must be washed in cold water on a gentle cycle so make sure you follow those instructions. You will want to make sure that your detergent is gentle and not use any bleach when washing your comforter so you don't risk damaging it. If you are able to wash your comforter at home in your washing machine, then there are a few things to consider when drying it. Follow the instructions on the label as far as dryer heating instructions and also add dryer balls or tennis balls to the dryer to help fluff up the comforter. Due to the size of the comforter in the dryer, it may only dry on the outside and you will have to run the dryer a few cycles to get it totally dry. Your best bet is to find a spot to lay out the comforter and let it air dry. If your comforter label says that it is not machine washable then it is time to take it to a professional cleaner so they can make sure that it will be cleaned without any damage.
