Alcohol is a polar solvent, which isn't very good for cleaning grease. Benzine (lighter fluid), hexane etc. are non-polar solvents and are far better for grease. Essence Renata is heptane, which is also non-polar. -
Interesting observation. I generally use Essence Renata or washing benzine, i.e. solvents similar to lighter fluid for any manual cleaning tasks. I'm happy with it.

@oldhippy - yes, cleaning them by hand in solvent removes the risk and all the time searching for them when they wander. I do the same for the very small screws. I also really like the coffee filter paper recovery technique, Richard - wish I’d thought of that before I sent a couple of dial feet screws down the drain one fateful day. 🙂

My usual method of pre-cleaning is to use peg wood to 'peg the jewels' then once this has removed/dislodged the gunk use a pointy type cotton bud dipped in IPA to clean the jewels and larger watch items. However, this weekend I was trying to remove that awful graphite grease (or at least I think it was) and the IPA was having a tough time lifting it. I switched to naphtha (lighter fluid) and the gunk was gone in a second. I am now questioning my use of IPA, why don't I switch to naphtha as my follow up cleaning solvent after pegging? Thoughts?

Your father in law has asked for it cleaning so you should go ahead. Clean first and then as Waggy said said polish by hand. I use autosol but it is probably very similar to Flitz, it depends on what is available in your country.
