First, it was the Wall Street Journal on laundry detergent. Now the venerable New York Times has spoken. We are using too much dishwasher detergent, which messes up the machine, necessitating expensive repairs. Ditto for dryer sheets in the dryer. Ditto (as we've already figured) for laundry detergent.
An expert--someone who does repairs and hence does not benefit from your detergent use--suggests we use between 8 and 10 times too much! That would mean--for laundry detergent--that my 3 bottles of generic purchased for $1.50 each, would provide not 50 loads as promised, but at least 400. I guess I'm set for a while.
Ah, and note to Mr. FS who is obsessed with saving water: You are NOT supposed to rinse dishes before putting in dishwasher. That is an order, backed up by scientific fact.
