How do I soften old, clumped together powdered dishwashing detergent?
By Deborah from Louisville, KY
Probably the best thing to do is carefully open the box or you might have to cut off the top with a pair of scissors. Pour the powdered dish washing detergent in a plastic bag and break up the clumps with a rolling pin or a heavy spoon. Then store it in a plastic container.
A piece of soft bread works with clumped up brown sugar so it will probably work with dishwashing clumps. Wait a couple of days to see if it worked. The bread will get really hard when used in brown sugar and it makes the sugar stay soft. I did this once with sugar that I thought I would have to throw away because it was so hard I couldn't even break it up with a knife.
I agree with MCW except that after you have got it down to clumps, I would put it in a blender to get it back down to a powder. afterwards, store in an airtight container to prevent it happening again.
