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.

Markd51, nice informative post. I follow exactly the same process except with the Walker Audio Prelude and brushes. The light scribbing with the brushes in the manner you've described has given me far better results in my VPI 17.5 than using the included nylon bristle brush.

One additional thought: be sure the brush or surface of the LP is well wetted before applying brush to LP surface.

Cheers,
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.
yep- i wiped out a beautiful near mint chet baker album by leaning too hard on a specfic section where there was a small smudge---you should let the cleaning agent sit for a few minutes and then lightly brush for 30 seconds following the grooves but i learned the hard way, don't keep rubbing a section---now it ticks when it gets to that area
Agree with everyone that recommends only a light scrub, not a heavy scrub. Cleaned a couple of batches yesterday, and so far, they sound great. No damage that I can tell. Very little in the way of pops or ticks. No grunge. In fact, overall, this batch is NM- (after cleaning), and that seems pretty darn good for 30-50 year old records!

I appreciate the references to steaming, and did look up some of those posts. Frankly, I'm just afraid of what would happen if my wife caught me steaming a record...it's hard enough every time a new package of records shows up at the door...
Eweedhome the worst thing that will happen when the wife sees you steaming is you will have to use it for all the other things it does so well. Stains, wrinkles, general cleaning and on and on. No really i was a hold out on steaming and like i said above it works and i wont look back.
Now if i could only find a way to scale back the amount of static developed by my 16.5. I only make one or two passes with the vac but man the static is hair standing. It seems some lps are worse than others in holding a static charge. The thing is the spindle is grounded on a 16.5 so you would think the charge would drain.
