Cleaning records. How often really?


Suppose, they have just been machine-cleaned and are played maybe two times a month in a regular environment.
Also treated with Last record preservative and kept in sealed outer sleeves.
Once a year or so?
Just don't tell me before each play, yeah, I heard of this insane approach.

Bill, it is my understanding that all records are pressed with a thin coating of a mold release agent applied to the stamper. If the stamper is not so treated, the LP's resist detaching from it after the cooling phase of pressing.


This seems to be true, but according to what I've read on Vinyl Engine, not every pressing plant uses it, and if it's used, it's a judgement call by the operator on when to use it. RTI was one example given as not using it.

Release agents are used for tool and die parts in manufacturing, wherever parts are being molded.
Once a record is fully and effectively cleaned, there should be little need to reclean- if you get a thumb or fingerprint on the record while handling it, the oil from your skin can attract loose contaminants, like dust, and that oil will not be removed by dry brushing or dusting; when the record is spinning, a vortex action is created, which draws dust onto the surface- that can be brushed off after the record is played; if you thoroughly darken your room, and use a small, high intensity flashlight, you are often able to see a fine layer of this dust on your gear; if you use a cloth or brush to dust it off, it just floats into the air, to resettle again. (We aren't in a 'clean room' environment). Inner sleeves can shed or leave lint. I think the issue of 'mold release' is overblown. I have spent a lot of time cleaning old copies - some take some work and multiple steps/methods, but once clean, it is rare that i need to re-clean. Static can be a problem, but there are solutions for that too. I try to minimize the amount of dry brushing I do, because I find the most brushes shed and can contribute to more static even though they are labelled as "anti-static." I also find that the anti-static gun is overkill and hard for most people to use effectively.
Stop scrubbing Bill! According to Last, the preservative bonds to the vinyl of the LP at the molecular level. Scrubbing won't reverse that permanent bond.
Oh, wait a minute Bill. The Last Preservative is not designed or intended to remove the mold release agent (allegedly, if you prefer) found on new LP's. Nitty Gritty at one time offered a product named First for that purpose, but it's no longer available. The Preservative is to be applied to an LP after it has been completely cleaned. I don't know how widespread your opinion of the product is, but as always, better to error on the side of caution, especially when an application is permanent.
