Homemade Way to Clean Acid Rain From Car Windows

Acid rain is rain water that contains high amounts of acidic components that include nitrogen oxides and sulphur oxides. "Clean" rain water is slightly acidic, with a pH of 5.6, but acid levels can vary based on geographical location. Pollution from vehicles and power-generating plants are the primary sources of acid rain. Acid rain that has dried on car windows leaves behind residue that creates cloudy or darker spots on the glass. You can use some homemade remedies to remove acid rain from your car windows.

Homemade Remedies for Acid Rain Removal

Wet newspaper with white vinegar and wipe down your car windows. If the acid rain spots remain, soak a rag in the white vinegar and apply it to the spots for 10 minutes. After 10 minutes has passed, wipe down the affected area, and the spots should be gone.

Spray a small amount of oven cleaner on a rag and wipe away acid rain spots. Wear rubber gloves to protect your hands, and prevent accidental damage to your vehicle's paint by always spraying the oven cleaner onto a rag, and never spraying it directly on your vehicle.

Dust acid rain spots with baking soda, and then use a damp rag or a toothbrush to scrub the spots directly. The baking soda acts as an abrasive agent that will break up the acid rain spots without damaging the glass.

Combine 1 part white vinegar and 3 parts water in a spray bottle, then spray acid rain spots and wipe down the glass with a rag or paper towel. The vinegar is a strong acid that will break up acid rain spots. Wipe down the glass and surrounding painted surfaces thoroughly, as vinegar can potentially damage vehicle paint.

In the event that acid rain has left behind mineral deposits on your car windows, use a very fine ball of steel wool to gently remove the mineral deposits. Rub gently to avoid scratching the glass.


Reduce the build-up of acid rain on your vehicle by taking it to a professional car wash every two weeks, and apply a fresh coat of wax to painted surfaces every three to fout months. Use a water hose to rinse windows after rain showers if you suspect higher acid levels.
