Horror story
I just finish detailing me car and of course it rains while I'm in the store. I leave the parking lot and things are drying up but there is one pretty large puddle I can't get around. Just a few inches no big deal. I'm thinking to myself this is odd because the rest of the lot looks pretty dry by oh well I crawl through. Then I smell something odd. Well, it's not a few inches of water but tar. The backtop sealant stuff. Why it's in the middle of the abandon parking lot I or why it looked just like water I dunno. I go to the first carwash I see I spray it all off but it's too late mostly. THe fresh wax on the paint allows me to scape it off with a fingernail but most of the underside of the car is baked on. The heat exchangers are covered as is the case. Now I'm pretty torqued so don't call me an idiot for driving through it... I know. Now I have something to do in the garage... O joy!

Might try a couple cans of engine degreaser. It should melt the fresh tar. Good luck.

Petrol or white spirits will disolve and wash it off. Make sure area is well vented though!

kerosene is the main ingredient in bug and tar remover. as well as crab detergent, for future reference.

I'm in South Carolina... Columbia. Funny thing is there was nobody around it just must have fell off a truck or something. The paint I'm not so worried about, it will come off with the fresh wax. But it is everywhere on the underside. Really baked on the exchangers.

Go to your nearest small airport and buy a couple gallons of Jet "A" fuel. It's around $2 a gallon, and it's what a lot of companies sell as kerosene.
When I worked at our helicopter base, I use to clean the undercariage of our fuel truck with it. Gets all the tar off. Make sure the area you are working in is well ventilated though, and free of any ignition sources if you spill some. ------------------ Matt Chamblin 78 911 SC |

Most of the commercial asphalt sealers that I have used in the past recommend clean up with mineral spirits after the product has dried on brushes, squegees, rollers, etc.
However, as mentioned above, Oil Flow Safety Solvent is another option that I have had good success with in the past. It will still involve a lot of elbow grease, but its a pretty effective product for this sort of situation. I purchase it from Larry Reynolds at Car Care Online. He's been extremely helpful to me in the past, and may be able to offer some additional assistance if you want to contact him. The following excerpt is from his website, www.carcareonline.com: OIL FLOW SAFETY SOLVENT & DEGREASER A neutral pH, solvent based, water soluble liquid solvent. Colorless, non-foaming and rinses clean with water leaving no residue. May be effectively diluted. Removes grease, tar, oils, adhesives, tree sap, rubber marks, exhaust and many other stains considered difficult. Do not use on polycarbonate or polystyrene. The only product that will easily remove wheel weight adhesive without harming the wheel finish. Great for removing oil stains from concrete floors. Test all solvents prior to use to ensure compatibility. Stock Number Package Size List Price C.C.S. Price 11001 16 oz. Pump Spray $13.00 $11.70 11002 1 gallon Jug $44.00 $39.60 Good luck!

Try Simple Green or other similar biodegradable degreaser. Castrol Purple works well.
I havent tried it on tar specifically, but it will remove undercoating so I expect it will work fine for tar. Spray it on, let sit a few minutes, then take it off with a pressure washer. Repeat until it is all gone. |

Xylene. Its a paint thinner. Spilled this on asphalt and the tar on it, well it became soft almost instantly.

One word of caution: do not spray any of these products recomended on heat exchangers if they are super-hot. Get motor up to temp, then let it cool for 15-20 minutes at least. Last week I sprayed Gunk engine cleaner on piping hot heat exchangers,(I've done this a hundred times before with no problem), and it ignited. I had a bonfire going under my 911 for a couple of minutes- managed to get it out, but those were among the longest couple minutes of my life!
