I like my cars to be clean but find that they are constantly covered in small brown spots. I can't get them off easily even with repeated washing. Local hand car wash does a reasonable job but still some remain, they tell me it comes from trees. They come off with a fingernail easy enough but there are hundreds of them over the screen and bodywork. Recently had my conifers lopped if that is of any relevance.
Has anyone else experienced this or can offer advice on removal.
Pulled in to Tesco car park this afternoon, just about to get out when I noticed a row of trees planted decoratively in the hedge. All Lime trees which are notorious for dropping gallons of sticky gum on anything unfortunate enough to be beneath them. Pondering what idiot ever thought them suitable to plant in a car park I moved elsewhere.
Apparently genuine Turpentine is good for removing sap residue, I'm told you should avoid Turps substitutes.
Thanks for the replies, no easy answer in my case then. I have always had this to varying degrees but particularly bad at the moment. Am wondering if there is some kind of polish that would prevent them sticking so hard.
The coating on the paint tends to start to go soft at quite low temperatures - mechanically working the surface when heated can, and almost always will, cause a permanent change in the appearance of the paint.
The "gallons of sticky gum" that falls from Lime trees is actually the aphid excreta I mentioned earlier. The aphids feed on the tree sap, and what falls on cars is what comes out of the aphids as a result. It is often euphemistically referred to as 'honeydew'.
