Varn Products produces a Metering Roller Cleaner , Product Code B015019, that is made up of 96% Petroleum Naphtha and 6% Diproplene Glycol Methyl Ether. Anchol Lithkemko also produces a Metering Roller Cleaner - NC, Product Number 7427, that is made up of 98.2% Lacolene and <5% D-Limonene. These are two that I am aware of and I am sure that there are many others that some of the other Printechers can identify as well.

Concerning your other question here is a partial list of other uses.

According to Gary Jones at GATF in a July 10, 1997 E-Mail it can be found in:
1) Blanket and roller wash - This includes a wide variety of cleaning solutions including metering roller cleaners.

2) Copper plating solution - This is used to place a thin layer of copper on carbon steel rollers in the inking train. The carbon steel rollers are principally used to distribute the ink evenly into the inking train. They will become desensitized due to the fountain solution and repel the ink. The copper plating makes the rollers more ink receptive.

3) Blanket Fix - There are several different names for this type of product, but it is used to temporary restore a blanket's thickness after a "smash". A smash occurs when the thickness of the substrate exceeds the thickness of the printing nip and since the blanket is the only material that is compressible the substrate causes the blanket to become permanently indented or damaged. Examples of smashing occur when a folded corner or two sheets are fed simultaneously through the press. The blanket fix will swell the blanket back to original size until the job is finished and the blanket is either replaced or repacked.
