Look up the Yellow pages under chemical dealers. Get good quality stuff as impurites in the solutions will settle as a barrier on contact surfaces. AS say this. I got some good stuff made by E.Merck (India). Paid about 150/- for each 500ml bottle.
People are known to use nail polish remover instead of Acetone but I understand this has some additive oils to protect the fingers and this is not good for the heat sink and CPU.

Man they are highly INFLAMMABLE liquids - no courier will accept them !! I am sure you will find these 2 liquids in chemical stores in Chennai. Look up the Yellow pages or ask around where the shops selling raw chemicals are located. If you dont get E.Merck look for Sarabhai or any other reputed make. These are common stuff - you should get them in any town in India.
EDIT: ask your drug store where the chemical shops are located - they should know.

@ freaky,
if you cannot get that acetone etc from Emerck then just get a bottle of "Technical" grade acetone. it costs about Rs. 8 to 10 here in mumbai. it does a wonderful job of cleaning not only the chip surface of thermal compounds , but can be used to clean the pcb and other smd components like resistors, caps , VR's etc ......
i have being using it for the past many years.....
incase you want to remove any residue left on evaporation of acetone take an ear bud and moisten it with distilled water and swipe it off.
@ eazy: this is not a contradiction of your suggestions which is good and highly recommended but subject to avialibilty and the cost factor. but do try this cheap solution sometime and post back ur observations .....

Thats OK dude.
But it is something I do all the time - waste money on stuff - buying the BEST. Just my silly way of doing things. I bought my stock of these 2 solutions a couple of months back and it will last me forever. My last 500ml bottle of Alcohol lasted me about twenty years !!! I dont remove my HSF off the CPU untill I am doing an upgrade which would be MAX twice a year. Thats why my tubes of AS 2 and 3 and 5 and Ceramique are all almost full - used MAX 3 - 5 times each. I used most of the Alcohol to clean tape heads and such stuff.
Check out the E.Merck bottles.... comes with a certificate of impurities which is printed on the label. Considering these will last me for the next 20 years the cost is insignificant.
deejay said:No Kidding !!!!!:huh:
I wonder how many "hours" a 500 ml bottle of alcohol will last with some of our members here ......hehe (J/K)
HEY you are not supposed to drink this stuff you will go blind - J/K
Yeah serious about the twenty years. I dont use it that often. I think more of it evaporates then what I use.

Yes Acteone is a solvent and will disolve any "minute traces of Thermal compound and the collected dirt / impurities" like you said - here is an extract from the AS instructions page....
......AND they mention....
By the way Prime had mentioned to me a while back that he had got these ArctiClean products - which to me seem to be imported relabelled Acetrone and Alcohol
I have no idea of prices. Must be expensive.@deejay ...bud... AS mention that cotton swabs and fingers are a No-NO ... they leave behind cotton fibres and AS says -
and an important instruction from AS...

I never use fingures or any other body part to apply AS5 directly.
if needed i cover my fingure with plain, clean sheet of plastic and do the spreading part, especially on the base of the h/s. and then remove it with tissue paper (no acetone or solution needed to remove the the AS5 from the base of h/s completely. since a minute thin layer of AS5 is preferred there as it fills the microscopic pits nicely)
After using the moistened cotton swab on the core part i use a hair dryer (on full setting) for about 5 seconds to blow away all the fibres , dirt particles etc on the surface of the chip. the added benefit of this is that it also pre-heats the heat spreader over the core to about 45C which is ideal for applying AS5.
and eazy , that technical grade acetone that i spoke about earlier does not contain any fragrance oil. actually it smells like that solution which the doctors/ nurses use to clean the body surface before applying injections....although the label on the bottle says "not for medical use".
actually since the price of this liquid (acetones) is so less (Rs.9/- for 20 ml bottle) i many a times use it to give a "acetone bath" to the gpu chip surface. these thermal compounds it seems have a great love for the small resistors and caps on the chip surface (surrounding the main core). they somehow find their way there eventually. disrupting the normal , rated, capaticance and resistance values. (i use a magnyfying lense to observe this ) and never ever use any pointed metallic pin/objects to forcefully remove the minute traces of thermal compound from underneath or beside these smd components. You will only cut the minute traces on the chip surface. (personal expirience)
by doing the above i have brought back to life many a "damaged" graphic card..........hehe

HA HA !! ..... other body parts..... HA HA !!
hyeah: No man..... I did NOT mean to say that you suggested this ... only included it in because I have heard of people "fingering" their AS onto the CPU
I use the rubber bulb available for 25/- at Lammy road for such jobs. Good directional air flow.
I read that the air flow from a Hair Dryer as well as the suction of a Vacuum Cleaner creates Static Electricty and this can do damage inside a computer. What do you think ?

I mentioned this in my post above.. this is from AS.....
and I think it is not easy to remove AS from skin and it will make you SICK if it enters your mouth via the finger !!
....and if you still want to use your fingers than consider using a toothpaste as a Heat Sink Compound :rofl:
