White residue on stylus


I have found that when i look at my lp under a 30x microscope i can see what looks like a clear liquid or maybe a crystal like substance in the grooves . This is in a very small area but there are a number of these throughout the album. The album has been cleaned 6 times using the following process with AIVS cleaning system.
Enzyeme formula ,light scrub and soak for 30 min. then steam and vacuum.
Super clean formula , light scrub soak for 30 min. and steam and vacuum.
I have repeated this 5 times, with an inspection with the 30x microscope each time. After each cleaning the lp is getting cleaner but the clear substance in the groove has only reduced by about 50% . On the last clean i lightly scrubbed for about 5 min which did reduce it a little more. I have noted the location of these deposits in relation to the label and i am able to view it after each cleaning to monitor the progress so far. I am sure the pops i here are these deposits.
I notice when i play the album i have a buildup of white powdery residue on the stylus that is easily brushed off or removed with a Magic eraser lollipop.

Does anyone know what these deposits are or what is the best way to remove them?

The albums are New old stock direct to disc that have been stored sealed for about 27 years.

Restock, I did not have the problem of white marks on my Music Matters LP's. Perhaps I was lucky or there are only a few with the marks.

I assume by Micro cleaner you mean Micro Care, the cleaner is called Premier and it works wonders on mold release, which is what it was designed for.

I'll look carefully at some of my new LP's and see if any have this white contaminant and then test to see if Premier works for that as well.
Albert, after you spray the Premier on the record surface, do you vacuum it off or just wipe it off with a soft rag?

Thanks,

I use Nitty Gritty cleaning pads, but anything that has a soft "velvet" type surface would work. I would avoid those super large pads as they tend to soak up too much Premier rather than distributing it into the LP grooves.

I've also used the pads that come with Last Record Preservative with good success, although it's easier to damage the LP scrubbing with it, compared to the wrap around design of Nitty Gritty.

Another link, this is the Last applicator brush

With either applicator, Premier evaporates so quickly you would think it's done no good, until you compare sound of LP's treated with Premier and without.

I think it's important to use Premier first. That way, any dislodged debris will be dissolved and vacuumed away in your Walker, Audio Intelligence, Mo Fi Enzyme or other cleaning fluid that follows.

Since my other post, I took a look at my Music Matters and Acoustic Sounds reissues and none have the white residue.

That does not mean it was not there, all but a hand full have already been cleaned with Premier using my RCM "string" type record cleaning machine, followed by Mo Fi Enzyme or Walker (I have AVS, Walker, Record Research, MO Fi Enzyme and other cleaners laying around).

If I find an LP with the residue problem, I will test with Premier and report back.
Albert, thanks for the response. Just to clarify whether we all are talking about the same white marks: here is a thread with a picture of the white marks I find on Music Matters, AP and some Cisco LPs (all pressed by RTI):

What ugly stains on an otherwise great LP. However, it looks more like something from the jacket or sleeve rather than a pressing defect.

I'll look over a few more of my Blue Note reissues.
