|The ideas related to cartridge cleaning are many, and most serious collectors would never
think of polishing an "old obsolete cartridge". It is OK to clean an "old obsolete cartridge;"
simple paint thinner will do a great job without polishing the cartridge.
With the three tooth chuck (pictured on the left), it is very quick and easy to clean
an "old obsolete cartridge" with a little paint thinner and a paper towel.
Be careful: paint thinner is very flammable.
Now for the newer cartridges (as even new cartridges get tarnished in time), I say polish
them so they look new, as they are new anyway but it is up to you.
This is a great tool to speed up cleaning or polishing and is easy to use on any drill.
The cartridge goes on and off easily and cleans easily with your paint thinner, or polish and
clean at the same time with your polish and cleaner compound.
Wipe on, let it set a 1/2 minute, "spin wipe" off the dirt and polish at the same time.
The average cartridge takes one minute to clean and/or polish.
