I use Adam's Towel & Pad Revitalizer

If not using a detergent specifically formulated to clean Microfiber Towels use a liquid detergent free from dyes and perfumes with the machine set to warm water, and no fabric softener. The pods can leave residue from the pod itself if not completely dissolved during the wash cycle. Powders may not completely dissolve, leaving gritty detergent residue remaining within the towel.
When drying use medium heat and no fabric softener sheets.
