How to clean the Dirty (Shaded) dog lp's ?

I have some new records that have that too and I think it is a pressing defect. Although I have been lucky and my new LPs that have the grey areas in the vinyl don't make noise. If it is the same thing, you can't remove it.

Christian, I guess I'm lucky as none of my shaded dogs have this issue. If you are hearing background noise, I might suggest Gruv Glide. I like this product and it certainly knocks down the kind of hash you describe in less than pristine records.

NOT FUNNY SAM, you've further voided your warranty, fella!

Rockitman;

Back in my school days I ran some LP's through a 240V 3 phase vacuum tube ultrasonic cleaner. That little beast was filled with DI water and a weak mix of Alconex. Alconex is a labware cleaner specific to ultrasonics that purports to leave no residue.

I have to believe the no residue hype, I was doing XRF analysis and there was no signature from the cleaner in the prepair'd samples.

Alconex seemed to remove fungus from garage sale LP's... but I think in some cases the fungus just ate the LP monomers and from there on out the LP was just noisy.

Pay no attention to Sammy.....he's hypoxic...... been on his bicycle for too many miles breathing exhaust fumes from all the sightseeing tourists.

I can't tell you how many sealed or NM shaded dog and other lp's I have that have blotches of whitish grey residue that does not come off no matter how hard I scrub with enzymes, alcohol based surfactants and even 5% distilled white vinegar. Nothing seems to remove this stuff and it makes the record crackle when the stylus encounters these area's during playback. Does anyone know what I am talking about ? Does anyone know how to remove it ? TIA

Do you have a picture of this residue you could share?
