40 Mule Team Borax
I have used Borax for many years. The last 3 boxes (new design - coincidence?) have been filled with huge lumps that I have to pound out with my meat tenderizer.
After buying the first lumpy box, I called their toll free number. The rep said the problem was probably caused by where the store had stored the boxes - too damp, etc. She sent me some coupons.
The next 2 boxes I bought at different stores - just opened one today which I had stored in garage so it was not near any water. The lumps are even bigger!
I do use cold water mostly, but even using hot water does not dissolve these lumps. Since they don't seem to be taking care of this problem, I need to switch products. Does anyone have a suggestion - Oxyclean??
