cloth bag washing
I recently got Mom's Model XXX Electrolux. She hadn't used it in ten years, and hadn't dumped the bag before putting the machine aside in favor of those stick vacs (which she replaced five times before going into assisted living, but that's another story.)
After "apropriating" the machine when my avaricious sister was out of the country on vacation (ha, ha!) I dragged my new treasure home, and took a whiff. No way was I going to bring that stinky monster into the house without a good cleaning!
I dumped the bag (wearing a dust mask and gloves) into the trash can, and then filled up a pan of cold water, enzymatic laundry detergent, a scoop of Borateem, and a cup of white vinegar and scrubbed away, using one of those soft rubber bristled brushes. The first panful of water got rid of most of the junk. I repeated twice, then rinsed several times, adding a cup of white vinegar to the final rinse. I dried it for two days in the sun.
It turned out so nice I almost hated to put it into the now-cleaned bag chamber to use the vacuum. And the suction, always good, only improved.
I'd love to get my husband to fabricate some kind of metal plate to fit behind the bag door to accept the type C disposable bags, though.
