1cup on ammonia to your load in the washing machine. Takes smells out.

Borax and sun and wind.

I use white vinegar too.

FYI, the only thing do not like about my water saving wash machine is the inability to SOAK stuff.

I learned that my front loader washing machine didn't do much for cleaning the mildew smell out of clothes. The older front loading machines get the mildew smell in them and if you don't take your clothes out immediately they will start to smell. Used vinegar and baking soda and it took me 3 washings to get the smell out.

When the plumber misdiagnosed my leaking washing machine problem, I bought a basic top loader machine without any bells or whistles. What a difference it made. Turned out that I had a cracked pipe and didn't need to buy a new washer afterall. Even though it ended up costing me an extra $350 for the new washer, I am glad I bought a new one. My clothes smell a lot better than they used to. The one fly in the ointment is that you can just soak your clothes as the washer empties the water out after 15 minutes.

Try vinegar in your wash & rinse cycle. Works good

Try OdaBan from Sams..It is great stuff...

All the above should work ..... if all else fails get a bin bag, add fabric and then add a generous amount of baking soda, close bag and leave it a few days.
