Does Simple Green Damage Car Paint?

Does Simple Green Damage Car Paint

Apparently, any car wash left to dry off on a car’s paint would leave a stain, and sometimes, such stains are not easily removable, leaving you with the only option of scraping the area to repaint it.

If you allow Simple Green to dry into your car’s paint while washing, it could lead to paint damage, especially if you frequently allow such to happen.

If you dissolve simple green in water, it becomes safe to use on your car, but you shouldn’t let the foamy, dirty water dry on your car. For this reason, it is best to wash your car under the shades so that the dirty water won’t dry up quickly due to sunlight.

That is to say, simple green does not damage car paint unless it is left to dry up on the paint, and this has to happen many times before damage is feasible.

How To Wash A Car Exterior With Simple Green

There are many car wash soaps and solutions produced by Simple Green; here, we’re talking about the “All-Purpose” cleaner, which is pretty common in most homes.

  • Wet the car (rinse the entire body)
  • Pour out your Simple Green cleaner into a bucket of clean soft water and make it foam
  • Dip your washing soap or towel into the bucket and start washing
  • Focus on one part at a time, and when you’re done washing a particular part of the vehicle, rinse off immediately before moving to another side.
  • Don’t allow the dirty foamy water to sit too long on the car paint
  • While drying, use microfiber towels

This applies to manual washing. If you prefer washing your car with a pressure washer, ensure that you’re using the right nozzle, pour Simple Green into the foam cannon and start washing.

Note: while using a pressure washer, be careful how to spray water on your engine (if you’d be washing the engine too) to avoid damaging some components that do not need to come in contact with water.
