How do you get rid of nasty smell from the washing machine?
Buy one gallon of distilled vinegar and fill your washing machine with hot water. Make sure you fill it to the brim so you may have to add water from a bucket. Pour in the gallon of vinegar. Let the washing machine run the full cycle- but without a wash in it. This will clean up the built up residue left by detergents. Do this every six months.
