Does using Kerosene and Diesel with Detergent will not affect the clear coat? How about using CarPro TarX for removing Tar and Claying process to remove other foreign materials.

I tried something similar to this on my Linea yesterday by using kerosene alone. It removed all the tar spots and some small scratches too. Some spots were tough to remove so had to apply some good amount force to remove it. Later in the dark I found that wherever I had applied kerosene swirl marks were more. Confirmed it once again by applying kerosene to one part of the same panel. May be the tar spots itself caused the swirls while being removed. Also read on the net that kerosene removes any wax on the paint surface thus removing the protection. So try this technique only if absolutely necessary. Now looking for some good wax to offer protection and removing the swirls. In the day time car really looks brand new. I don't think using detergent is a good idea. If kerosene alone can cause swirls, just think what effect a detergent can have on your paint.

If its dash plastic. Use dettol. If its body panel. Its best to use kerosene.

Guys, using kerosene to get rid of tar spots from your cars painted surfaces may not be advisable but is a practical solution, and just that you dont cause any harm always soak up the tar marks for a minute or two before you use any force on them or u'll simply cause bad whirl marks, also you've gotta follow up with some super fine 3M rubbing compund and liquid wax. Now, again no need of force, be gentle. as you all know kerosene takes off whatever wax thats on the car's paint, so its gotta be rubbed back on and by doing a bit of rubbing and polishing u'll smoothen out the paint and wax it as well. happy motoring
cheers.

Smile Re: DIY: How to remove Black Spots (Tar) from your car

My Fiesta had seen some tar spots on the drivers side all along from the bonnet to the Boot. The spots were not large but spread out. Maybe the drive when the road laying was in progress was the cause.

Applied diesel as suggested in the thread and allowed it to soak for a couple of minutes and voila with one single clean of fresh cloth and the spots were gone. I have asked the wash attendant to give it a soap cleaning in the coming weekend, will the diesel layer make the colour of the car go dull?

Please don't wait for the weekend and get the diesel washed off with shampoo as soon as possible or there are changes of discoloration on the paint surface if the diesel is allowed to sit for a long time. even though you wiped off most of the diesel, traces will definitely remain unless the surface is washed with some kind of detergent based car wash.
and after the wash its best of you could give that part a coat of wax. Mr Miagi style.. wax on..wax off

hi folks
some mad fellow, hooligan, had poured a mugful of tar on the bonnet and front windshield of my car today. The car was parked next to my house's compound wall. I am not sure who or why did this.

Initially i had tough time just using washing detergent, water and thick cloth. There were thick portions of tar dried up in several places.

Then I read somewhere on the net that WD40 / peanut butter could help. I had peanut butter unused and I applied that over thick tarred surface. After a minute or 2 minutes while rubbing, the tar used to get mixed with the peanut butter but removing the mixed ones off the surface was a terrible pain. I had to use a thick cloth and rub hard to remove the mix and when it came off, it rubbed on the unaffected surfaces as well. Very painful and slow removal of tar.

I checked out for alternatives and came to know there was a little turpentine saved during the last wall painting work. I dipped a wet cloth in that turpentine and rubbed and it was slowly removing the tar. I was afraid this could remove the car's original paint as well.

Then i took the help of my Dad to buy some turpentine but he did not get any in nearby hardware stores. He brought sheenlac (thinner) 1 ltr for Rs 140 and said that may work. Again I was not sure if this would remove the tar alone and leave the paint as it is .

I dipped the same cloth again in a container with some sheenlac / thinner and rubbed on the tar. Initially i rubbed hard as i was conditioned to rub hard earlier but later realised that the thinner within few seconds could thin out the tar and become liquefied and get detached from the car body. I started rubbing softly and in round motion over all tar affected surfaces and slowly but steadily all major tar portions were removed. Every now and then, i had to dip the dirty cloth in the bucket of detergent mixed water and wash away the removed tar that gets collected in the cloth.

Every time I had to apply some thinner, i had to take up a new portion of a cloth and dip in the thinner fluid and rub round and round. After a while there were tar linings and stains which were caused by rubbing the already tar dirt collected cloth everywhere around the bonnet, which I had to apply more washing detergent water and wash away. Did the same in several iterations till the surface became 95% clean. There are still stains of rubbing over tar in very affected areas (where that idiot had poured excessive tar).

I may try another round later or tomorrow, but now have to be at work.


Protect you car is my advice after my experience.

Hey Rajesh, Its a very old post for me to reply to it now. But recently I saw a lot of tar marks behind the front and rear wheel of my Polo. It was a sad sight as no amount of cleaning or waxing would help to remove the tar stain.

Anyway I read here that diesel would help and hence I went and bought half litre of diesel and then sprayed it at the tar spots. Initially I tried rubbing but it was taking a considerable amount of force to get the tar moving. Then I just sprayed and waited for around 10 minutes and then washed and wiped with a clean cloth. The stains were completely off, a couple of stubborn ones needed a bit more of persuasion.

If you still have tar stains on your car, which I hope wont be, then try this method. Use diesel, spray it on the stains, wait for 5-10 minutes and then wipe off. I am 95% sure it should work.

Also one of the car washing places ( not the 3M or high end ones ) told me that they can do a diesel wash, which is quite common.

I would recommend doing a shampoo washing and waxing after the diesel treatment.

Hi All,

Firstly I'd like to thank you all for the information provided here. I found it useful & used it to fix my problem & save me big bucks. I wanted to share some pics & info on what I did as mine is probably the worst tar splatter here.

Here's how it looked. This is after a lame effort to clean it with car shampoo & before I checked team-bhp.

Prevention is better that cure, so if you don't want this to happen to your care make sure you drive slowly after driving over wet tar to ensure the tar doesn't splatter back on the car.

I did not have diesel or kerosene handy so I used an equivalent of WD-40. It is called Rustofree & costs about 100 bucks.

This is about 15 seconds after a healthy spray. I wiped it off immediately after this & followed by a wet cloth to take away the balance spray.

Formula 1 Bug & Tar remover to clean tar sprayed on Windshield:

A couple of days back at mid night while I was returning back from office, I had to drive through a patch where they were relaying the road. We had to drive through the side and while doing so, the guy who was spraying tar on the road inadvertently raised the hose and sprayed it on the car just ahead of me. My car (Ecosport) was also smeared with tar on the bonnet, driver side door and the windshield. The spots were so minute but it was too much that it gave a matt feel when you slip your hands on the windscreen.

I was so worried and as usual searched Team-BHP for remedy and came across this thread. Thanks for the suggestions, I was confident that this could be removed.

I had just bought a bottle of Formula 1 Bug & Tar remover last weekend to cleanup some tar deposits near the mudflaps. I was skeptical in using the product on the glass but decided to try it as it was mentioned that it can be used on any part in the exterior of the car. I first tried it on the front quarter glass and the results were awesome. waited for a while to check if there was any reactions but none.

Hence I started cleaning the windshield with water and newspaper to ensure that the windshield was otherwise clean except for the tar. Then sprayed the liquid on one portion of the windshield and used my hand to gently spread it evenly on the surface. Waited for a couple of minutes and then used a soft cloth to clean it. Had to use a little bit of force to remove the tar. They came off perfectly clean. I then cleaned the entire windshield one portion at a time. Then I again washed the windshield with water and wiped it clean with newspaper to ensure that there was no residue.

The Formula 1 Bug & Tar remover worked really well on the glass and it didnt leave any oily feel. That was one reason why I didnt use Diesel as I was worried that cleaning the glass would be a tough task if diesel was used.

Drove the car in rain and used the wiper; it worked fine. So my windshield is spotlessly clean with all the tar removed. Haven't cleaned the tar on the painted parts as I didnt get the time to do. Will do it and update the results in a couple of days. Planning to use the product as it mentions it is "Clear coat safe".
