Recommendation of cleaning brushes for Dry-well temperaure inserts

[esware]

Hi all,

We have a Dual block dry-well calibrator from Fluke. Any suggestions on what type of brushes used for cleaning the holes on inserts for both the hot and cold side? Also,where to purchase them?
The outside of the inserts are easily cleaned with emery cloth, just cleaning the holes in the inserts become a challenge.

Thanks,
Pat

Go to a sporting goods store and pick up a gun cleaning kit in a caliber appropriate for the diameter of the hole in the dry block you want to clean. Hart Scientific/Fluke formerly sold a virtually identical item for this purpose but it is no longer available. I think you'll find the gun cleaning kit performs equally as well.

Bore Snakes work rather well
