I have a Cabrio and use a homemade powder form. What I do is after I grate the soap, I spread it out on a platter and let it dry out for about 2 or 3 days, depending on the air in your home. Then I put it in a food processor. It becomes a fine, fine powder (please wear a mask when handling). I've had no problems with this method; I've been using it for about 4 or 5 years.

Homemade laundry detergent (soap) is low sudsing, so you can use either, depending on your preference.
