Considering the inflating cost of waterproof spark plugs, has anyone had success with pneumatic powered abrasive spark plug cleaners?
I have never tried one so I am curious if they are worth the investment, there are some fairly inexpensive ones I've seen advertised lately.
Stop by your nearest airport and ask for the FBO (Fixed Base Operator) with a maintenance shop. Drop in there and ask how much to clean 4 shielded plugs. When I ran a large shop I used to have walkings quite often and I'd show them how to do it and let them do it themselves and charge then a small fee for using the equipment.
If you want to replace the plugs with new or even get a set for later before the price goes up more, here are the links. I bought a new set of spark plugs a few years back. The prices have gone up a bit but aren't as bad as some people were reporting (upwards of $18 each).
