Time to put away the Onzow ZeroDust? | Analog planet

These latest microscope photos from WAM Engineering LLC (WallyTools) provide dramatic evidence that Ozow Zerodust leaves stubborn, difficult-to-remove residue on "clean" buttons and overhangs. It's a disturbing discovery.

This first photo shows a "clean" Onzow Zerodust pen with residues attached:

Here the same pencil after a long and difficult cleaning process with a carefully applied bristle brush and liquid pencil cleaner. Notice that there are still some scraps left:

Here is another picture of ZeroDust before cleaning.

And here is the same pencil after painstaking cleaning with stiff, running bristles. Be aware that there is stubborn residue

Equally worrying is that the residue is also sticking to the overhangs.

Here is the same overhang after a very fine clean.

Here is a photo that shows the height of the overhang that the material can adhere to.

There are other pictures showing similar debris from Onzow and the even stickier DS Audio cleaning pad. Analysis of the residue shows that it is not silicone, but a type of polymer. A more detailed analysis of the material will be carried out and reported here as soon as it becomes available. In the meantime, you have the choice of whether or not to continue using one of these products, but I will use a stiff brush and a solvent-free button cleaner (I will be using Audio Intelligent, but Disc Doctor or other liquids that do not dissolve the cement should be safe in Ortofon Replicant and other types of sticks).

Thanks to JR Boisclair from WAM Engineering for these pictures.
