Cleaning old thermal paste.

post #1 of 13
Thread Starter 
I'm redoing my thermal paste and I've seen many ppl use "rubbing alcohol" and a lint free cloth/coffee filters.

By rubbing alcohol, I have here hydrogen peroxide... Which is rubbing alcohol... Is that safe to use? It doesnt say all the ingredients so I cant see all the chemicals in it... What is safe to use to clean the old paste off?

EDIT: Seems like most people use rubbing alcohol is the safest, but acetone probably morks a little bit better...

99% alcohol

goof off
Isopropyl Alcohol (dunno what this is)
Brake Cleaner

Hydrogen peroxide (H2O2) is not the same as rubbing alcohol or isopropyl alcohol (C3H7OH).

Isopropyl alcohol is in the clear bottle. Hydrogen peroxide is in the brown bottle.

Definitely don't use hydrogen peroxide. You can get isopropyl basically at any drug/ department store in the first aid aisle.

The higher % the better. I use 92% and it cleans great.

For me its in kind of a frosted white plastic bottle. 93% should be sufficient as there is almost no appreciable difference between that and 100% except its vastly cheaper. Coffee filters or lint free cloth like you said. Its perfectly safe, don't drink it though.

EDIT: The bottles I get look similar to this:

I use Acetone, Laquer thinner would be the best but it would also resolve the finish on your board.

I initially use paper towels and rubbing alcohol then use some of the alcohol wipes we have at work for cleaning electronics, they are lint free.

Hydrogen peroxide is not rubbing alcohol.

Definitely do not use hydrogen peroxide. That stuff is a solution of 2% hydrogen peroxide and 98% water. Go with isopropyl alcohol and some coffee filters. Cheap and effective.
