Every method has its evangelists, I don't feel the need to ask anyone how they feel about steam cleaning, I love my steam cleaning and ultrasonic.
I have collectors from all over the world send me records to record and almost all of them comment on how when they get returned how much cleaner they are than when they left....quite a few VPI 16.5 owners in that group
I won't fight-argue with what you say.
But remember, a lot of people mistakenly believe the RCM cleans, when it does not do any cleaning at all per se.
If the fluids cannot loosen the found-various types of contaminants on the record, and in the groove, suspend those contaminants, do so without causing any serious harm, and then a rinse water removing all further traces of those cleaners, and contaminants, then it won't really matter if you're using a VPI, Loricraft, Clearaudio Double Matrix, Keith Monks, etc etc machine.
With the proper cleaners, I can believe when a person says that his DIY RCM machine does every bit as good as a VPI, or other type of machine that uses a wand type vacuum. Because all the bar vacuum in the world may not remove them properly-fully if the cleaners are not correctly designed, nor properly used.
Agressive methods may give a certain desired result, yet cause some other undesireable results.
For instance, another thread, with a user mentioning the use of Labtone Glass Cleaner on his records. Well OK, lets's look at the MSDS of the product.
From what I recall, the product contains an acid, as well as sodium. Well, I can remember from Beer drinking days, that the ole beer hands used to say to never clean your favorite beer glass with soaps-detergents, to sprinkle plain old table salt in the glass, swish, and rinse with clean water.
I'd agree that for glass, sodium is probably a very efficient cleaner, and there's no products in it, like food grade silicone, which many dishwashing detergents are claimed to have. Is it good for your records though?
Or is acids, or alkalis, even in dilute form?
I seen the effects of steam, or I should say hot water cause to a record, warping it. Firstly, I wouldn't wish to place those sort of stresses on a record by hand, why would I wish to with heat?
Steam-hot water, without some other ingredients is said to only sprseadome the contaminants over a record, and not truly detach them well enough for removal with a vacuum system. They'll have a tendency to re-attach themselves very quickly again in the groove.
I'd rather have a product which will loosen the contaminants, float them into a liquid suspension, which is then much easier to then remove with the vacuum process.
One important aspect of using cleaners, is giving them the needed time to do their job. Thirty seconds, or a minute may not be enough time to fully loosen, and act upon those contaminants. Mark
