    Hi guys my CR-V is parked under trees and when I washed it for the first time in a while I found there is black staining on most surfaces that won't wash off. I am assuming it is sap from the trees what is the best/easiest way to get it off. Thanks.

    Peanut butter, doesn't matter if its smooth or crunchy, rub it on and let it sit for a bit.

    Clay bar might help also. Either bar or mitt. The mitt is a new fangled invention, prefer a bar myself!

    Ok I just tried autobrite tar and glue remover and it did not touch it next I tried a clay bar which shifted some of it but will take a lot of scrubbing to get it all off I think it is a fine clay though perhaps I need a coarser one.

    Black staining doesn't sound like tree sap to me, more like some sort of industrial fallout. Either way, a more aggressive clay should sort it - after all, it removes overspray - try the Bilt-Hamber medium but make sure you lubricate well with water or you'll create a different problem!

    It was bilthamer clay I tried not sure what grade it was, the car has not been anywhere near any industrial plant so don't think that could be that. Part of the hedge is a Christmas tree we had rooted years ago and I planted it afterwards it is now about 40 feet high and I wonder if it is resin from that.

    It's more likely to be Honeydew which is secreted from aphids or the ants that are after them.
    Honeydew has a consistency like treacle and like treacle it will go black over time.
    Best to look for something that will remove treacle, LPA or even WD40 should do it, but wash it off. Depending on the area covered, it may take a lot of repeated application.
