My apartment has a pretty cheap dishwasher and Muncie’s water isn’t the softest, this leaves lots of soap residue on my glasses. It doesn’t rinse off very easily and looks terrible. I looked on line, and found that baking soda should work.
So I put all of my glasses in the sink and covered them with lots of baking soda, then filled the sink up with hot water. After a few hours soaking and washing the baking soda off, the soap scum is mostly gone.
