Small black spots on car body.

Hi all , i have been having difficulty cleaning my car since the rains started . There are small black sticky spots all over the car, which on cleaning , start spreading but dont come off even after using car shampoo. They do come off if i rub cloth dipped in petrol on them . My query is , is it safe to clean the car body with petrol or could it make the paint come off. Is there any other way of cleaning these spots conveniently and manually ?

  Thanks.

Its probably dried up grease. Don't use petrol - try car wax/polish and see if it can be removed.

Can car wax be used as a cleanser ? I thought it should be applied after cleaning. Which car wax should i try ? I have been using simoniz shampoo cum wax liquid.

Well wax can be used to dissolve the grease I guess. I'm sure others on this forum will have a better remedy...

As Rohit said if its grease then use wax to remove the stains. If you find that it's tar (dambar) just use cloth and wipe it by using diseal.

Diseal is a good removing agent against such stains.

How to clear tar from car

Hope it clears off.

It feels more like tar . If i use diesel , is there a chance of the paint coat being damaged ? Since this happens every second day , could i use diesel that frequently to rub the spots off ?

Tar spots won't come that frequently on the car. If only you drive through a road just being tarred there is a possibility. So using Diesel is not all that bad.

If this is a frequent problem, however, get your car waxed regularly (once a month). The wax coat will prevent the tar from adhering firmly to the paint coat, and then it can be easily be wiped off.

Don't ever try to remove stain spots by brute force. You will end up scratching the clear coat, and there will be ugly rub marks that are whitish and dull. That is an eyesore. use gentle techniques wherever needed.

Thanks for the prompt replies .

   To sum it up .. i should use diesel (cloth dipped in diesel ?) and follow it up with a wax coat . Someone told me to use Waxpol rubbing compound to get rid of the spots . Any ideas how good and safe it is ? Any other good wax brands?

    Yes krishna , i did experience the dull rub marks after using cloth dipped in petrol. Will it not happen with diesel ?

The marks are most probaly due to your rubbing (these are actually minute scratches in the clear coat, which then does not reflect light as evenly) and not because of Petrol. Don't use force, wipe gently. I am not sure, but the overwhelming consensus in the community is using Diesel for the tar spots. Maybe it is safer for the clear coat.

Will try diesel .... hope it's safe..  also have heard of people have a diesel wash for their cars .. should be safe.
