Re: thermal paste cleaning Q..

If the base of your HSF is copper or nickel get a decent Iso-Propyl Alcohol/Rubbing Alcohol/PCB Cleaner with ~ 70% purity or ArcticClean if any other material just get a 200ml bottle of PCB cleaner from your local PC walla/Chemist that costs ~20-50bucks(it's a multipurpose cleaner for your PC and NOT LCD).
 
Re: thermal paste cleaning Q..

I only use Isopropyl alcohol !! I thin you being a DOC will understand that the other concoctions in the market are 70% strength only.
 
Go straight for 100% IPA, cause any % of water included will reduce its solubility parameter values substantially. To get pure IPA in small quantity like 500ml, buy from Laboratory Chemical dealers, almost all of them will have stock of 500ml IPA bottle of brands like sigma-aldrich, Fishers, Rankem, Loba, Nice etc... It will cost you btw 100 - 150 rupees. If you could not find any, then PM me.
 
Rahkri is right isopropyl alcohol can be best procured from laboratory chemical dealers a few more brands, besides what he has already mentioned, available in India are BDH, Qualigens, Merck & Ranbaxy. Basically any organic solvent can remove thermal paste but isopropyl alcohol will no dissolve PCB components or leave ion rich deposits which may cause short circuit. I am both a doc, have a lab at home and a audiophile DIYer, though new on this forum.
