Garment Washing
The machine is rated on garments plus stones. Load it on garments alone and the drum is full before the batch is.

Stone to charge with this batch of garments
Ground pumice does not simply disappear — it leaves as sludge that has to be screened out of the effluent and cleared from garment pockets, and both are real costs beyond the stone itself. Enzyme or combined enzyme-stone washing trades that load for a chemical one; compare on total cost per garment, not stone price.
