do you decrease the amount of detergent for towels?
I have a Bosch Nexxt 500 washer that I've had for a little over 3 years. Up until a few months ago I was using Charlie's Soap exclusively and had no problems with oversudsing (unless I washed something that had previously been washed in Tide). I switched detergents because my whites were really dingy, and I've been getting really good results with both Method Smartclean and Vaska herbatergent.
My only glitch with the new detergents is that I sometimes get oversudsing with a load of towels. Do you decrease your detergent amounts when you are washing a load of towels? If I do towels in a mixed load it's usually fine, but if I run a load of towels I sometimes, but not always, get oversudsing. Any ideas?
