After years of use, I could hardly see through my table saw’s guard. While at a car show, I heard that polish for renewing aluminum wheels also worked to clear up old headlight lenses—so I tried it on my saw’s guard. After two applications, it was as good as new! Since then, I’ve cleaned all my guards and my face shield as well. –Ross Bierma
