I have supplies under the kitchen sink, bathroom sink, on shelves going into the basement, and a shelf in the basement. I use boxes to keep items contained on my basement shelves. I didn't discard anything but I straighten up a bit. I have a mix match of cleaning supplies because most were given to me. I'm trying to use up my supplies and eventually just have a couple brands that I buy. My shopping list always has the same stuff and brands. It makes life easier.
