With a really dirty load, use the same amount of soapnuts, but only fill the machine half full. (This will give the laundry some room for the clothes to move freely). As with all laundry cleaners, it may also be necessary to use stain remover to eliminate resistant stains.
Yes — absolutely sure! We’ll admit that soapnuts are a VERY odd-looking laundry detergent, and vastly different than anything most people have ever considered washing with. But they do a GREAT job of cleaning! Sometimes you might see a tiny bit of brown discoloration on the washbag, but that’s just saponin and it’ll wash right out in the next load. (We think it’s particulary cool, because it’s extra evidence that something CLEAN is happening in the wash)!
