Well, from turntables to vinyl care, anyway. Just came across this, posted a few weeks ago on Amazon. It refers to the DiscWasher we all knew and loved as children:
To those of you lamenting that this product "isn't like it used to be" I hate to break it to you, but even then you shouldn't have been using it. It is incredible that to this day people still don't understand what goes on with a record, but here are the facts so you know what you are getting into.
Making a record is like making a waffle. Do waffles fall out of the machine cleanly? Not unless you spray it, and the same goes for records. The press is sprayed with a mold release compound and this compound remains on the record and discwasher, old or new, does not remove it. In any case when do brushes clean well? Brushes only push dirt around, if you want the dirt gone you have to use a vac to suck it up.
Records are also damaged not how you think. Vinyl is soft, yet at the stylus tip there is incredible pressure and heat however what happens is it creates a shock wave that emanates from the point of contact and the most direct point of exit from there is.... yes, the OTHER side of the record. This shock wave reaches the other side, the side ends, and the force of it blasts out tiny pieces of weak vinyl on that side which remain in the groove. Using discwasher only pushes these bits about... if that... they remain in the groove. So when you flip the record to then play that side, the heat from the stylus melts this debris and the pressure welds it in new spots on the record creating, that's right, pops, ticks and other noise. That is where this noise comes from, and why it cannot be removed from cleaning. You damaged the record and then welded the damage to a new spot. It's there forever.
There is an answer but in short vinyl is a lifestyle. Before any record is ever played it should be cleaned on a record cleaning machine (like Nitty Gritty) using a solution designed to remove the compounds etc.. on it's surface. The cleaner breaks it down, the machine removes it, as in actually removes it because it sucks it off. Then the record should be treated with Last record preservative. This hardens the vinyl surface a few micros of an inch and prevents the vinyl from breaking from shock.
That's it - Never play a record not cleaned, (because if you do your stylus is now contaminated as well) and once cleaned treat it to preserve it. If you do that, and use a quality setup, you will be amazed. I own thousands of records from the 80's, many played hundreds of times and none of them make any noise (well.. the ones pressed well to begin with that is, but that's a different issue) and I mean any noise. My records do not have pops and ticks. That is what is required, and this product is not even close. In fact tests back then showed, because this brush becomes essentially a filthy mop, that using it spreads MORE debris on the record than was there before. Do not use it.
