I think steam or the ultrasonic of the Audio Desk are best for actually getting stuff out of those microscopic grooves. The "microfiber brushes" claims used by some cleaners are in fact so relatively large that they would straddle several of the truly microscopic grooves of the LP instead of getting down in there and cleaning them out as some claim. Although certain chemical release solutions and a vacuuming should be effective too.
And yes, the mailing option for offering your own cleaner for use might not be for everyone.
