If you’re like many of us (especially many of us with children), perhaps you’ve found a few things that were left out in the rain and snow when they shouldn’t have been. Not to worry — you can clean off any lightly rusted items in an earth-friendly way by using some of the items in our Fantastic Four cleaning kit (baking soda, vinegar, lemon juice and salt).
First, mix equal parts salt and cream of tartar, moistened with enough water to make a paste. Use this paste on metal outdoor furniture, for example, or rusted metal parts on an outdoor grill. Apply the paste with a soft cotton cloth and set the item in the sun to dry. Wipe off and repeat if necessary. Afterward, rinse clean. You can also try making this paste using lemon juice and salt, rather than cream of tartar. Be sure to keep the amount of lemon juice or water you use consistent with making a paste thick enough to not slide off any vertical surfaces.
