THAT is what I was worried about... the penetrative qualities of WD40 or something similar. I think I'd rather pay 50 bucks and head down to the car wash at the pump.... they'll spray clean the whole thing with a mist-hose and I'm not driving around wondering if my engine is going to explode through my bonnet.

For 50 bucks the pump side car wash guy can use Diesel / Hair Shampoo / Cloth detergent / Soda / Vim / Soap / Pril / Harpic / rustoline / kerosene / used oil or even diluted acid as he cant buy Autoglym or EB for 50 bucks.

Then I recommend WD40 than any of this flammable/corrosive agents, but dont ask me why WD40 cracks your plastic and rubber parts in the engine.

The guy at the pump will be using a proper hose with the right nozzle attachment on a mist-spray that shoots only water to get all the gunk out of my engine bay, and he'll be doing it with me watching him like a hawk.

I don't want my engine bay to be clean enough to eat off. I want to get rid of dirt and dust that accumulates on pipes and hoses and makes them brittle and leads to premature part failures.

Diesel is not bad at all. But why don't you guys try to buy some LA's Auto Degreaser? It cost you some 100 bucks only and available in all dollar stores.

WD-40 does not crack the plastic and rubber parts of the compnents of the engine. It is definitely a better option than diesel to use to degrease the engine. In fact, the M.A.S.S outlet where I have been servicing my cars for many years have also mentioned that it is safe to use and is non-reactive.

So, would diesel be a safer bet? But, isn't it far more flammable when compared to WD-40? And if sprayed on rubber, wouldn't it deteriorate much faster?

Diesel will smoke. Damage your gaskets. Ever fire your car if in contact with spark.

I dont recommend Diesel too to clean the engine.

To clean rust/oil residue you need a Degreaser or non-corrosive detergent.

To protect the engine from rust you need a protectant.

Then why you are using Fuels / Lubricants / Penetrants in Engines?

If you cant buy a Degreaser or non-corrosive detergent for 100 bucks, use Coca-cola to remove the rust and pepsi to remove the residues (?).

If you can't buy a protectant use Baby oil(?).

Havent seen any such product anywhere in Pune. Does anybody know where its available? Price info would be good too.

Are you serious about Coca cola/Pepsi? Does it really do the job well?? These colas are acidic, if I remember correct...?

And baby oil...?! Now I really don't wanna baby my engines that much...

I have read reports of these being used to clean tyres. Aparently, using them will bring that original clean black look to the tyres. I have not tried it though

Yes, PEPSI will clean your tyres and belts, even rubber parts. COLA is one of the best rust remover:

There is a rust-removal trick that works with Coke, though. Old-time mechanics who were faced with the problem of getting an old engine from a junkyard apart would take the heads off and dump cola into the cylinders. There's just the right amount of phosphoric acid in Coke to make that work after a few days. You could use Naval Jelly, but you have to thin it down to get it to go into the little crevices of the engine and, by the time you get it thinned out enough, the concentration of phosphoric acid is about the same as what's in Coke. Besides, there's always a Coke machine in the corner of a mechanic's shop.

Man, You are drinking it man...Do you thing your engine is precious than your stomach?

Lol... I'd never drink that junk! Also it seems that you need to have the rusted object immersed in cola for sometime, for it to work. Not possible for the purpose for which we are talking about. Anyway, havent used it any which way, so can't comment further...

Not seen any degreaser in any tyre store here. :(

Oh My senior, I just joked and dont try Coke.

TYRESTORE is a dealer in Chennai, its TYRESTORE - not Tyre Store.

Have you tried any Dollar stores? Or you can buy it online from this guy: http://shopping.rediff.com/product/a...mover/10254783

But I am not sure whether its original or not and why this cost that much. I used to pay only 99 Rupees in My Dollar store at Chennai.

Havent checked out any such stores lately... but will do so. I'm not optimistic though... haven never seen these kind of products there.

Yes, the cost + plus shipping is too high. Even the brand is not mentioned. Just not worth it.
