Product Review: Gunk: Liquid Wrench

Manufacturer: Radiator Specialty Co.

This is a product you can use to loosen screws or other parts that have rusted or otherwise "frozen" together, so you can move or remove them. I usually use it on squeaky door hinges, but found another use for it this weekend. My house still has 50's windows that were increasingly difficulty to both open and close. I got this idea to spray Gunk on the aluminum slides at the sides of the windows, so gave it a try. I'm so glad I did. It worked like a charm and now I can open and close the windows with ease and without giving myself a hernia. I highly recommend it for household use. It also works great on locks that no longer turn.
