Spark Plug Cleaner Harbor Freight

[Danisa Southmayd]

Goodlittle blast cleaner. Just be careful to not blast too much. The black diamond is very much abrasive. Also if you are going to keep it in your tool box close the input air pressure fitting with a cap. Otherwise you will end up with abrasive compound all over your box! LOL

I should have bought this years ago! This works so well and is so reasonably priced that any all aircraft owners should buy one.The only issue I have encountered is that the grommet that you stick the plug through can spin in the containing groove, and can push thru into the housing if you arent careful. But easily worked around and it just simply works!

Actually I am quite impressed. I set my compressor regulator to 80psi (10 psi below max recommended), gave three short 1 - 2 second blasts with the media, then another 3 second clearing blast and the plugs came out looking very clean. I had low expectations for my carbond up and oily plugs but they came out shining with a matte aluminum color. Just be heads up that the cleaning media can get wedged between the electrode and the fingers but is very easy to get out. I thought this was going to be messy but it wasnt. 5 stars.

An inexpensive cleaner that works okay except that the rubber grommet that holds the spark plug is slightly undersized for a 18 mm spark plug. If you push the spark plug into the grommet very hard the grommet will pop out of position. You have to sort of screw the spark plug into the grommet.

The cleaner worked well cleaning the plugs but the rubber gasket used to seal the plug into the cleaner had a very small hole. trying to push an aircraft spark plug into it would dislodge the rubber before the plug could enter. I had to remove the rubber gasket, stretch it over the plug then try to hold it over the hole to clean the plug. I need to find a punch to enlarge the hole to the proper size for these plugs. Other than that, it works fine blasting the plugs clean!

The abrasive that our supplier uses is "Black Diamond", which is an industrial abrasive that does not break down as glass beads tend to do. It will clean without leaving any residue (glass dust) or build up on the plugs.
