If you can bring yourself to buy some of that, that should work quite well for the purpose.
Just be careful not to buy freeze cracker spray for removing bolts - it contains release oil that will remain on your circuit and possibly lift off solder.mask or screen printing! Its aboult half the price of "proper" freeze spray.
