Machine wash 2 cups bleach gentle cycle front loader. 5min Rodiprime soak , verify no bleach fumes.
Vineger soak as needed for particulates.
I change mine once a week or when over flow. I use a lot of bleach, no suds on hand wash cyle.

I had bought 12 of them. Some of them where puralator brand. I'm not sure which brand but the seams came undone . You can tell the difference on how the quality of the seam. I sewed them up, I probably would not happened if I wasnt machine washing.
