Stubborn Poop Stains on 320-CS Exterior

JP2558

Our white 320 was bombed by some critter from up above which left several greenish splats each with a runny streak down the back, just above where the clamshell is attached. We tried using Meguires wash and wax, but that didn’t fully remove the stains. Tried wd-40, no change. Next we tried bug and tar remover and that didn’t help either. Lastly we tried rubbing alcohol, which with enough elbow grease removed enough of the stains to make the stains unnoticeable, however we can clearly see where the rubbing alcohol was used, and now we would like to wash it again, then apply something to fix the area where the rubbing alcohol was used. I’m thinking of trying a good paste wax, but would really like some experience based recommendations.

Thoughts?

Thanks!

if it is similar to calcium stains in your bathroom, try using a little vinegar mixed with rubbing alcohol and a spot of dish washing soap mixed in water. That will cut right through calcium deposits. It might work the same way.

@TourDeForth Thanks but we did try straight vinegar with no luck. The stains were not similar to calcium stains.

Have you tried a clay bar treatment?  Auto detailers use it to remove stubborn road grime. Full disclosure, I use it on my car and truck with great success but have not used it on the trailer. Make sure to use some kind of lubricant with it.

Try toothpaste in a small spot. That should do the trick. Make sure its minty fresh and use your spouse's brush, not your own.
Rubbing compound would also work but it might be a bit too aggressive so if you resort to it, use it very carefully. You will need to buff it up to remove the cloud it might leave.
