Lp cleaning - scrubbing records - any downside?


I've got a VPI record cleaning machine (which I've had since the 80's, stored for 15 years, and only started using again when I got back into vinyl last year...that's one sturdy piece of equipment!)

I've "modernized" by getting myself some Mo-FI brushes, fluid, etc. And, after reading a bunch of posts on Audiogon, I recently started "scrubbing" records while they're rotating--just short, with-the-groove scrubs, not too hard.

Amazing results. Much better cleaning of "problem" Lps.

So I'm converted. (Why did it take so long? Habit, I guess.) BUT, I have the impression that certain Lp makers (EMI and DG, in particular) used vinyl that at least SEEMS softer than other vinyl, and more easily damaged. And one of the 2nd hand Lp dealers I know is of the same impression...so I guess it's not just me.

Does anybody have any negative experience with scrubbing to report? Could it damage some records?

Many thanks.

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 .
Super clean formula , light scrub soak for 30 min. and steam.
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 3 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.
Does anyone know what these deposits are or what is the best way to remove them?
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. The albums are New old stock direct to disc that have been stored sealed for about 27 years.
