An overhanging branch has dripped tree sap all over your parked car. Or, you've just driven through wet tar and now there's black gunk all over your side car panels. Now what? Both substances are sticky, thick and can be extremely difficult to remove once dry. Unfortunately, many chemical cleaners can damage your car's paint. But, don't fret, there's a gentle tar and sap cleaner that works wonders on car surfaces -- you already have it in your fridge.
Simply rub a small amount of mayonnaise over the stain and let it sit for 15 minutes. Next, wipe off the creamy condiment, and the tar or sap should follow. You might need to use some arm muscle to buff out any stubborn stains.
