Absolutely.
If you are seeing residue after playing these Oxford (Albany) Indestructible records then:
1) the records were soiled and you're seeing residue that the diamond stylus pulled out of the grooves, or
2) your diamond stylus may be bad presuming you have the reproducer adjusted correctly relative to the record surface

I have several thousand Albany Indestructible cylinders in my collection and my own personal experience with the blue-grey variety in both 2 minute and 4 minute is that most of them play pretty awful. Most of the blue-grey variety Albany Indestructible cylinders in my collection appear to have shallow grooves as though they were pressed using worn masters or perhaps the celluloid was inferior.
Shallow cylinder grooves with the Albany Indestructible cylinders ( labelled as Oxford, Columbia, Everlasting {
not US Everlasting} ) generally yield lower volume and greatly increase the tendency of the stylus to "wander". And it's rather difficult today to find ANY 4 minute Albany Indestructible cylinder that does not skip a groove during play at some point.
I have a book here in my collection, "CYLINDER RECORDS", written and published by Duane D. Deakins, M.D.
In this book, Dr. Deakins indicates in reference to INDESTRUCTIBLE RECORD COMPANY (1907-1922) in the first paragraph, "...A FEW RECORDS WERE MADE OF BLUE CELLULOID BECAUSE OF AN ERROR AT THE FACTORY SUPPLYING THE CELLULOID."
Now, whether Dr. Deakins' reference here is based on period document research from the Company is not known. From my perspective, there were a LOT of Albany Indestructible records made of this blue celluloid - far too many for this to have been an error. But, who knows?
