With summer on its way out, now is a good time to clean your gardening tools so they’ll be pristine and ready to use in the spring. If rust has encrusted trowels, shovels and shears, reach for this common item in your kitchen pantry: black tea bags. Brew a pot of strong black tea -- using about four bags -- and allow to cool. Pour the tea into a bucket, and fill it with cold water. Soak the tools for one to eight hours, depending how rusty they are. As the tools soak, the tannic acid in the tea gently attacks the rust. Remove the tools and scour them with a coarse brush or sponge. Your tools will be as good as new!
