A cool tool can be any book, gadget, software, video, map, hardware, material, or website that is tried and true. All reviews on this site are written by readers who have actually used the tool and others like it. Items can be either old or new as long as they are wonderful. We post things we like and ignore the rest. Suggestions for tools much better than what is recommended here are always wanted.
8-Inch Bottle Cleaning SetI have been using these brushes for a couple of years. They work great. I use them in the kitchen and the shop. They are small enough that I can get into small and curved containers or parts. I used to try to use Q-tips or toothpicks, which never worked. They can also be shaped to get into curved spouts.
