PeterCD's method is very effective, but vapor-phase polishing in acetone is even better, where you heat the acetone, and sit the part in hot vapour.

It has a flashpoint of -20 degrees C, which is why I mentioned the cold vapour bath only.

Best to use a double boiler if one wants to try the fast track brave route using heated acetone.

I use acetone at room temp which is way above the -20C flashpoint....Can you explain ??

Basically its a level of safety that you're comfortable with, I dont have a problem with room temp acetone, I use it in the garage and house, but I dont heat it up to 80deg C like one does with a smoothing vapour bath.

Wiki source

At temperatures greater than acetone's flash point
of −20 °C (−4 °F), air mixtures of between 2.5% and 12.8% acetone, by
volume, may explode or cause a flash fire. Vapors can flow along
surfaces to distant ignition sources and flash back. Static
discharge may also ignite acetone vapors, though acetone has a very
high ignition initiation energy point and therefore accidental ignition
is rare.

Very true. We didn't use an open flame, but a hot plate outdoors.

If you're using ABS you can use a cold acetone vapour.

First it would help to know or see what you mean by polish.
If you need a lot of cleanup to get a good looking part you should start by optimising your print settings first.
I usually only clean up the brim and the support material but not the surface of my prints as it is not required.
