How to Remove Yellow Stains from Leaves on the Car?

[WalterDella]

Rinse the area with tree sap using water to prevent the paint from being scratched by sand particles during wiping. Soak a towel in hot water and place it over the area with tree sap. Once the sap melts, it can be wiped off. If hot water doesn't work, pour some white vinegar, soapy water, or alcohol solvent onto a cloth and wipe the affected area. The sap will decompose and can be easily removed.

Last time my car was parked under a plane tree and got covered with yellow leaf stains. These stains are mainly caused by tannic acid from the leaves seeping into the car paint. I first rinsed off surface dirt with warm water, then used a sponge soaked in car wash soap to soften the stains. Next, I took out the 3M adhesive remover I had at home, sprayed it on the yellowed areas, and let it sit for three minutes before gently scrubbing in circles with a soft brush. For stubborn spots, I repeated the process a few more times and finally rinsed thoroughly with clean water. It's best to avoid parking under trees when possible, and washing the car weekly can effectively prevent this. If you notice leaf accumulation, remove it as soon as possible to prevent the sap from staying on the paint for more than 24 hours, or it may turn into permanent yellow stains.
