Melting hardened nail polish to use

When using nail polish, it feels like a waste to throw it away, but if I keep using it, it leaves brush marks.

If you mix in acetone, the color naturally fades and the process of hardening repeats.

If it is not to the point where it needs to be discarded, there is a method to melt it using a double boiler.

You can reuse it if you melt it in a double boiler at a temperature that is not too high.
