Be very careful! I reckon (and this is purely an educated guess) that acetone could strip all the oil off the bores in a nanosecond. I certainly wouldn't start pouring random fluids down it's gullet. Powertune is a known quantity and designed for the job.
You could try redex I guess, but I tend to agree with hightower - I'd have the spanners out and start investigating.
