Oldaudiophile, in case you did not know it, @antinn is a high class expert on cleaning technologies.
For relatively clean records I use 80KHz exclusively, although I have used 37KHz on some very dirty specimens with good results. Temperature is an issue, as antinn suggests. Body temperature is safe for vinyl, but colder is less good for cleaning.
