Archat are you seriously suggesting diesel or wd40? Not to demean anyone here but diesel is known as dirty fuel and wd 40 is used to clean rust and other tough sludge.

All I'm saying is that these extreme chemicals have long term effects on the clear coat. And yes these cause clear coat fading and damage.

IronX, TarX, megs super degreaser, optimum power clean are paint safe. I suggest stick to these. And in 99.99% cases either of these are enough.

Yes I'm!! You are not meant to leave the diesel or WD 40 forever on the paint. Apply with a cloth, leave it for couple of minutes and then wash with shampoo and apply wax.

If you have read the MSDS of TarX you'll find that it contains >60% of Naphtha (which is a petroleum distillate present in WD 40 also). TarX also have some limolene which is used as tar remover and paint stripper (!!!) too (which imparts it's citrus smell). I've personally used diesel and WD 40 on my car without any harm. Actually I prefer WD 40 more. It can be used to remove glue residues after removing stickers.

So, why spend more when you can achieve same result without any harm if used correctly?

The costly ones are IronX and TarX from CarPro available from greenz car care.

Thankyou for the suggestions. This is not for thar. For thar, I have used petrol/diesel/kerosene many times quickly followed by lot of water and happy with that.

The contaminants I want to get rid are some tiny dots here and there. No idea what they are. They can be felt with hand and removed by scraping with a nail or heavy rubbing with kerosene which I do not want to do. Looking for a smoother way to remove these. There is also what seem to hardened gum on the roof. There is also black marks on the roof. I think these are hardened gum remains left from the use of cellophane tape to stick flowers few years back. These are no more like gum, really hard and kerosene has no effect too.

Is there any thing I can do to get rid of these?

For hardened gum residue you try WD 40 or IPA - you'll have to soak the spots a bit. Also you try a mild polish like the Meg's ultimate polish to get these stains off.

The other spots that you have mentioned seems to be bonded contaminants on the paint. Clay is the best thing here.

PM notorious (a member here). He has some clay for sale which is quite affordable.

For removing the marks of the cellotape wash your car with a car shampoo and then wax it with a cream based wax (carnuba) using an aplicator. It worked for me.

So I got wd40 & tried it. After 3 sprays & some vigorous rubbing & scratching with my nails I got the gum out. Sadly the calcium deposit didn't go! Tried hand rubbing some Meg's UC but that didn't help.

New question : How do I get rid of the calcium deposits?

If that's indeed calcium deposit, a bit of diluted vinegar might help! (or straight vinegar if diluted one doesn't work) use a mf towel to agitate!

Thanks sohail99! Have tried 50:50 vinegar:water on chrome/glass parts. Was a little apprehensive of using it on paint. Will definitely try it out coming weekend.

Also, received Meg's Clay Bar from Sanjay, & Engine Degreaser from SnapDeal today! Guess its going to be a detailed weekend!

Will post before-after & if possible in-between pics soon!

Adding to what Archat has already said - the indian version of the WD40 called Zorrik88 (pidilite) clearly mentions that it is 'paint safe'.

The reason why it actually works is because 'tar' as diesel, furnace oil, petrol, kerosene is also a part of the petroleum sludge. As a rule the most volatile of these will be first extracted. The last things to go are petroleum jelly, naptha, ship furnace oil and tar (from what I remember!). As a rule if you use a product which is higher in the chain it will dissolve the lower product. - pure petrol will mix with diesel, diesel will mix with tar, etc. So if you dont allow it to settle for too long, I dont think it will affect the paint.

Thanks torquecurve and archat for the advice. Really helpful.

Just try WD 40 /Zorrik and you will be amazed by it's versatility. It's great for cleaning the engine bay also.

.

WD 40 is also paint safe, but is it clear coat safe? How does it affect the clear coat?

If it was safe, then why are expensive chemicals like TarX given so much importance?

I want a clear idea about this As not much articles abut this are floating around on the net. Everyone says its paint safe. Wanted to be sure about the clear coat part.

Its 759 + shipping per 80gm bar. shipping to Bangalore was 60. So total of 819 per bar.

Not a technical answer, but I believe it to be safe, and have used it on my car. Clear-coat must surely be at least as touch as the paint layers below it?

People talk about using diesel on paint, when it is known that it cause damage. Anyway, with either we are not giving long exposure, just applying and wiping off.

If it was safe, then why are expensive chemicals like TarX given so much importance?

Ask the marketing departments!
