Acetone is a solvent and there is a good chance that when you use it to clean the surface, you will also clean the surface's lubricant. And maybe something else...
About the heads, I really don't know if it is OK. But I do not understand either why cleaning the heads. Head/surface contacts happen occasionally, and are not supposed to cause lubricant accumulation in the head. The lubricant itself is planned to not interfere with head function.
If you need to clean a head, that's because something really bad happened at head/surface contact. So bad that a dirty head won't be your worst problem...
And how do you apply the acetone? With cotton? Textile? It will leave remainders.
That's why all this story about using acetone sounds damn weird and dangerous to me. But... maybe I'm totally wrong and in that case I would like to hear from your experiences.

I have not much experience with VCR, because I don't even have one. However I remember seeing cleaning tapes, which used an abrasive strip.
I've seen a long time ago a cleaning tape for audio tape. You would need to put a few drops of a specific solvent into the abrasive strip before using it. But you would also need to wait a few minutes before putting the cassette, or the solvent remainders in the head would damage the plastic strip.
