ross163103 Posted August 28, 2022 Share Posted August 28, 2022 My neighbor has a large mango tree--the green type, that overhangs into the street. I don't park under it directly but I still get mango juice on my car. Does anyone know what will take this off the finish. I've tried various penetrating oils, waxes and other things and all have failed to take it off. Any ideas? Thanks in advance for any suggestions..

It's possible that something like strong rubbing alcohol or some type of vegetable oil could act as a solvent and dissolve it. Worst case, maybe Acetone or nail polish remover. Always test in an inconspicuous place. Link to comment Share on other sites More sharing options...

Your recommendation will strip the paint......???? WD40 or Sonax.. They both have a strong solvent that will not hurt the paint, forget the oil in it........???? 1 Link to comment Share on other sites More sharing options...

Yeah, seems like rubbing alcohol or mineral spirits are more recommended. Link to comment Share on other sites More sharing options...

Always test in an inconspicuous place. Acetone is the solvent of choice for fully polymerised paints, the OP should not use it under any circumstances. It would ruin the clear coat gloss. The sap from mangoes is actually a natural polymer itself. Hard to remove, detergent, water and elbow grease might do it. I doubt a non-polar solvent such as WD40 or turpentine would be effective, try methylated spirits. Not as aggressive to paint as acetone/nail polish remover. The other alternatives are buy a car cover, or park somewhere else. Edited August 28, 2022 by Lacessit 1 Link to comment Share on other sites More sharing options...

WD40 or Sonax will even eat through road tar without harming the paint, never be without it......???? 1 Link to comment Share on other sites More sharing options...

Road tar is a different kettle of fish, it's just the longest chain hydrocarbons being attacked by the shorter chain hydrocarbons in W40. Strictly speaking, it is not a polymer, just humongous carbon chains leading into waxes. Heaven knows what mango sap polymer is, my best guess would be polysaccharides, given the sugar content of a mango. Trust me on this, I was a chemist.

ozimoron Posted August 28, 2022 Share Posted August 28, 2022 Nothing will get mango sap stains off paintwork. It burns the paint. I used to have a mango farm and had a white ute (pickup) streaked with brown stains. 1 Link to comment Share on other sites More sharing options...

That's when the cutting compound or wet & dry comes into play if needed.. 1 Link to comment Share on other sites More sharing options...

Mango sap burns deep. Wet and dry and new pain is all that will work. The stuff is like brake fluid. It burns the skin quite badly as well.
