Things You'll Need
Nail polish remover
Mineral or bath oil
Lard or bacon grease
Keep the cleaning products that you use away from the painted areas of your color in order to avoid the possibility of damaging your paint.
Although trees can provide shade and beauty, some varieties also drop sap onto your car, leaving you with a sticky mess. If you happen to get tree sap on your windshield, don't worry. You can remove the sap fairly simply. You don't have to spend a great deal of money on expensive automotive cleaning products, as you can use a variety of products that you may already have right at home.
Apply a cleaning product to a clean, dry rag. You can use a thinning type of product such as nail polish remover or rubbing alcohol, or you can use an oil-based product such as mineral or bath oil, lard or even bacon grease.
Rub the cleaning product of your choice onto the tree sap that is on the windshield. Use small circular strokes with your rag.
Reapply the cleaning product and continue rubbing if necessary.
Wash the windshield with warm water and dish soap when you have removed the visible sap to get rid of any remaining residue or dirt.
Spray some window cleaner on the entire windshield and polish it with a lint-free rag or paper towels until it is free of smudges or streaks.
