If you or your loved ones ever go swimming and use goggles chances are the goggles fog up after a while. Often it is no problem to clean but at other times it can be a real annoyance. This tip I gleaned (from a book not the Internet!) really does work. It is so simple: just wash the goggles after use, smear some washing-up liquid on the lenses (inside and out), rinse again and leave to dry. If you do this everytime after you use the goggles I’ve found them to be good for 2 hours with no misting, If you do it less frequently they still last up to 30 minutes with no fogging (depending on other swim conditions of course!).
