Something I have tried and they seem to work pretty good is a product called Washeze..They are a 3-in-1 Laundry sheet that have the detergent, softener and static control all in one. They have the "he" low suds formula and work in all machines. For the Splendide you only use 1/2 sheet. Go to
www.WASHEZE.com or go to a friends site that sells them also, RV Space Savers/ Collapsible Kitchen Products.
