Can acetone be used on gold plated contacts?

2007

We are contemplating removing a sealing adhesive from a connector that we use in one of our products with acetone ⇦ on eBay or Amazon [affil link] Flammable! . We know the acetone removes the adhesive but don't know if the acetone will attack the gold plating on the connector contacts. Short term/Long term?

Thanks,

Acetone will not attack gold - the only thing that does is aqua regia. However, it may attack the plastics used in the connector assembly

Acetone looks like an impressive solvent.
BUT
It is highly flammable.
It evaporates so fast that it re-deposits much of what it removed.
MEK / methyl ethyl ketone is better or use one of the new citrous based solvents.

Just for the record; aqua regia is not the only chemical to attack gold but you are unlikely to come across them
