MY grandmother used white vinegar instead of bleach in underwear & socks. Worked very well,also I have used it in customers dishwashers & washers (both top & front load) & does a very good job of breaking down soap deposits,calcium deposits & such. No harmful left over chemicals to get into your clothing or on dishes. Remember in USA we don't heat the water like European washing machines do. We run hot & cold water to the washers & are 110 volt compared to only cold water & 220 volt (which is smarter) I did a lot of ASKO & other European washers years ago.
