Removing tar from painted surface

Maryland Pressure Washing
Does anyone know of a product that can remove asphalt shingle marks from a painted surface? I've tested quite a few products so far and I can't find anything at a price the owner will pay that will remove the tar, without removing the paint.

If you know of any product that will remove it please give me a call and let me know, regardless of how expensive it is. I've got to find a way to do this that I can spray on a chem and wash it off, it's too large an area to do spot by spot.
 
If it is a small spot you may try some adhessive remover and a rag.........thats what we used to get tar off cars when I was in the car business......sorry for my spelling
 
WD40. I have used it to remove asphalt from the backs of dump trucks with great results.

What kind of surface is it. What type of paint and condition?

My thoughts exactly Scott, an oil based solvent, "mineral spirits", "pitch oil", ................dont laugh dependant on the surface even a light fuel oil could be used even gasoline, just depends on the amount, surface that is painted, type of paint, and paint treatment. If you have a special pump for the working fluids you could actually spray it on at enough pressure and remove the tar very fast (containment would be another headache)
 
Okay, I guess I'm going to have to give some more details so you all can get a better idea of this site. First off, these marks cover an area thats approximately 84,000 square feet. No, that's not a typo, 84,000 square feet. The surface is concrete and it's painted with white latex paint. I'm trying to find a product I can spray on at either full strength or use through and M5. Either way doesn't matter.

I'd prefer to be able to rinse it off without having to brush it but first I have to find something that will disolve it without taking off the paint.

My suggestion would be d'limonene.
 
Yes I tried a butyl on it and a limolene based product. The Limolene base worked better but it had to be brushed and it didn't take it all off. It also softened up the paint pretty good but it will probably harden right back up again.

I'm only cleaning the exterior walls but it's a total of 6,000 linear feet by 14' tall.
 
It’s not wise to gamble with third rate or household solutions because they may end up damaging the paint or finish. Many are aware of the frustrating auto cleaners that remove grime and dust but leave intact the tar among other bake stuff.
From my far fetched experience, I can safely vouch for Car Guys multipurpose cleaner. Next gen technology has been used to ensure that the multisurface cleaner can lift oil based spots at their molecular level.
This multipurpose wash takes away the stress of buying and working multiple cleaners, one for each car part, such as inner dash cleaner, stain scrubber, tar and bug remover, and so on.
The best tar remover for cars should leave the surface free from grease and other sticky film. Others will just corrode the paint or finish. CarGuys brings back the tender touch of a car or other surface finish just as it was when new.
It’s actually a non-toxic hydro based formula that is absolutely safe both to the paint and your hands.
Although at $17 its price is relatively higher, it’s actually a saving because it replaces several other cleaners.
