Here is what I do and I was taught by a lady who sold linens at the flea market: Fill washing machine with very hot water. Add 1 cup Clorox II (color safe), 1 cup of BIZ and 1 cup of Cascade (dishwashing liquid) to the hot water Let washer agitate to mix thoroughly. Let water cool down to room temp Add all materials and agitate for a couple of minutes. Let soak 3 or 4 days.
If you have a small amount of whites, use just the Cascade in a bucket and only 1/3 cup
