Only time I ever used one was on aircraft type plugs.  Auto and small
engine plugs are cheap, I throw them away.  Aircraft plugs also have
"massive" electrodes, and can tolerate some quite a bit more material loss.

Al,

I use the cleaner anytime I remove a plug that I plan to put back.   Its 
normally on small engines however.

One note, I actually use a spot sandblaster that has the perfect hole size 
for most plugs.  I use Al oxide for media.

Never had a problem.

Have heard--no hard data--that blasting damages the polished coating on 
the ceramic insulator (that's what blasting is for, after all).  I 
think, given how relatively inexpensive plugs are that it's not worth 
the risk.

True - the plugs for the snow blower are between $5-10.00 each here, likely
cheaper on Amazon. 

Thanks all.

Anybody still using spark plug cleaners - such as the small air powered sand
blasters of old?

I'm looking at plugs for several cars, snow blower, etc. - and wondering
whether the cleaning is known to damage the plugs.  I don't recall that
being an issue when I used them years ago, nut I do confess that the newer
plugs seem to be made of more exotic materials.

Thoughts?

I have one of them and they  do work well.  They used to make sense back in
the day when lead would leave deposits, carbs would run rich and points
would burn, weak spark, etc., resulting in good, relatively new plugs that
were sooted or covered with lead deposits.  Also, if you had two-strokes,
they tended to foul plugs.

With modern ignitions and lead-free gas, plugs last a very, very long time,
and they probably are worn by the time that they get dirty, if they ever
get dirty. I also have read that sandblasting will round-off the sharp
edges, resulting in less efficient sparking surfaces (I do not know if that
is true).

Of course, the big bugaboo is the potential of leaving some sand/grit on
the plug and inserting it into your cylinder to scratch the bore.

I think the last time I used my spark plug blaster was to clean a lawnmower
plug or a chainsaw plug that sooted out.  It is always there, though, if I
needed to put a vehicle on the road and I do not have a plug to do it.  :-)

Best,

Subject: RE: [Shop-talk] Spark Plug Cleaner

=20

Answers here to many things you didn=E2=80=99t ask about=E2=80=A6  About =
aircraft plugs, where blasting is the most common, but mostly applicable =
to car and small-engine plugs as well.  FWIW, I=E2=80=99ve been blasting =
car plugs since the 60=E2=80=99s and aircraft plugs since the =
70=E2=80=99s.

=20

Blasting is still used on most aircraft plugs, same as ever.  Aviation =
plugs cost $25-$50-$75 apiece and up, depending on type and how much of =
a bargain hunter you are.  No big sales at the local auto parts store.  =
Very few owners replace plugs at every Annual or 100-hour inspection.  =
Piston aircraft engines have 2 plugs per cylinder, and flat engines most =
commonly have 4 or 6 cylinders.  Radial engines usually have 7 or 9 =
cylinders (or 3 or 5 on some antiques), and the really big ones have =
multiple rows of 7 or 9 cylinders.  Lots of plugs.

=20

The two largest aviation spark plug manufacturers, Champion and Tempest =
(originally AC) both publish blasting instructions and sell plug =
blasting/testing machines.  Quite obviously they approve.  Like a =
majority of individuals working mainly on their own planes, I =
don=E2=80=99t have one of these $1,000 to $1,500 machines.  The =
=E2=80=9CVixen=E2=80=9D brand one that most auto parts stores still sell =
for under $20 works just fine.  It doesn=E2=80=99t have the impressive =
pressure-tester where you see the spark jumping while the plug is under =
pressure, but that test isn=E2=80=99t really helpful 99.9% of the time =
as long as you do a good job of cleaning.

=20

As far as abrasive, I use a garnet abrasive because it indeed breaks =
down and exposes fresh sharp edges.   Most auto parts stores sell little =
bags specifically for use in plug blasters.  And if a garnet particle =
gets into the engine despite careful magnified inspection as part of my =
reconditioning, that particle won=E2=80=99t do as much damage as =
aluminum oxide.  But it=E2=80=99s probably not critical as long as you =
get all the abrasive out in the first place before reinstalling the =
plug.  Either way, abrasive is cheap to buy and lasts through many many =
plugs.

=20

There isn=E2=80=99t actually a shiny coating or glaze on the center or =
nose insulator, and the ceramic itself isn=E2=80=99t degraded much by =
normal light blasting.  What the aviation plug manufacturers DO caution =
about, however, it to avoid eroding the cement that holds the center =
electrode into the insulator.  With extended blasting the cement erodes =
and a well develops around the center electrode.  Not sure how bad it =
needs to get to be an issue =E2=80=93 I have some plugs with slight =
erosion and they work fine, don=E2=80=99t foul notably different than =
new ones, etc.

=20

To get the initial carbon off (because its=E2=80=99 a really slow =
process to blast 14 plugs completely without doing some initial carbon =
removal), I first use Hoppe=E2=80=99s #9.  Just set the plugs upside =
down in a rack and drop in enough Hoppe=E2=80=99s to fill the plug =
interior.  Wait an hour (15 minutes is actually enough most times), dump =
out the Hoppe=E2=80=99s, and  spray carb cleaner or Brakleen into the =
plug to get much of the carbon out.  Then blow dry, and then blast.  =
Speeds up the process immensely, especially getting the deep carbon out =
or at least softened.

=20

While cleaning, some of the carbon inside the plug=E2=80=99s outer steel =
shell is hard to remove.  Champion (etc.) sells a plug cutter tool =
that=E2=80=99s like a tiny curved saw blade, made to fit  into a =
vibrating engraver-type tool.  That makes fast work of the excess carbon =
around the outside.  Carbon on the center insulator usually comes off =
pretty easily.  Once you think you=E2=80=99re pretty much done.. you =
visually inspect the inside for missed deposits and any remaining =
abrasive.  A dental pick helps there.

=20

The other thing that=E2=80=99s important in reconditioning aviation =
plugs is to check the resistance.  There=E2=80=99s a resistor in =
virtually every modern aircraft plug, not for RF suppression but for =
good running.  If the resistance decreases (it can over time) the plug =
will develop a misfire.  RF suppression is handled by shielding of the =
magnetos, cables, and the plugs themselves, which have a heavy steel =
outer case.  You never even see the ceramic outside like you do on an =
automotive plug (except for unshielded aircraft plugs, which are =
increasingly rare).

=20

Massive electrode plugs have a large center electrode and (usually two) =
large side electrodes that are shaped to surround the center electrode.  =
The side electrodes can be bent in and out to set the gap.  While plug =
inspection and cleaning is part of every 100-hour and annual inspection, =
blasting can in time round off the edges of the electrodes and make the =
plugs less efficient, as the primary area for sparking to begin is at =
the sharp edges.  I=E2=80=99ve taken an ignition file to the tops of my =
electrodes a few times on older plugs to remove some of the =
blasting-induced rounding.  They look better, but I=E2=80=99m not sure =
it makes lots of difference in running.

=20

Plug manufacturers don=E2=80=99t recommend blasting on =
=E2=80=9Cfine-wire=E2=80=9D plugs, which are similar to platinum, etc. =
automotive plugs except the side electrode is a thin piece of platinum =
or iridium.  Those come pre-gapped and all you=E2=80=99re supposed to do =
is verify the gap, and if it=E2=80=99s incorrect replace the plug.  At =
$75 apiece minimum.  But they don=E2=80=99t foul much, which is why =
they=E2=80=99re used, and they last a long time.

=20

Final caveat.  Shielded aviation plugs are all heavy steel on the =
outside.  All the ceramic is inside.  If you drop one, it looks fine.  =
Even after carefully inspecting it, all the ceramic looks fine every =
time.

=20

But there=E2=80=99s an old aircraft mechanic=E2=80=99s saying that you =
only drop a plug twice.  First time on the floor, and the second time =
into the garbage can.  I=E2=80=99ve violated that a few times, but =
75-80% of the time the plug is either bad immediately or goes bad =
quickly =E2=80=93 within a few hours at most.  I=E2=80=99ve marked the =
plugs I=E2=80=99ve dropped and attempted to reuse, but after a few times =
realizing that the old saying is right, I haven=E2=80=99t reused any =
more dropped plugs.  A bad miss or worse really gets your attention in =
the air.

Aviation plugs cost $25-$50-$75 apiece and up, depending on type and how =
much of a bargain hunter you are.&nbsp; No big sales at the local auto =
parts store.&nbsp; Very few owners replace plugs at every Annual or =
100-hour inspection.&nbsp; Piston aircraft engines have 2 plugs per =
cylinder, and flat engines most commonly have 4 or 6 cylinders.&nbsp; =
Radial engines usually have 7 or 9 cylinders (or 3 or 5 on some =
antiques), and the really big ones have multiple rows of 7 or 9 =
cylinders.&nbsp; Lots of plugs.<o:p></o:p></span></p><p =

A'>Blasting is still used on most aircraft plugs, same as ever.=C2=A0 =
Aviation plugs cost $25-$50-$75 apiece and up, depending on type and how =
much of a bargain hunter you are.=C2=A0 No big sales at the local auto =
parts store.=C2=A0 Very few owners replace plugs at every Annual or =
100-hour inspection.=C2=A0 Piston aircraft engines have 2 plugs per =
cylinder, and flat engines most commonly have 4 or 6 cylinders.=C2=A0 =
Radial engines usually have 7 or 9 cylinders (or 3 or 5 on some =
antiques), and the really big ones have multiple rows of 7 or 9 =
cylinders.=C2=A0 Lots of plugs.<o:p></o:p></span></p><p =

Tempest (originally AC) both publish blasting instructions and sell plug =
blasting/testing machines.=C2=A0 Quite obviously they approve.=C2=A0 =

for under $20 works just fine. =C2=A0It doesn=E2=80=99t have the =

garnet particle gets into the engine despite careful magnified =

normal light blasting.=C2=A0 What the aviation plug manufacturers DO =
caution about, however, it to avoid eroding the cement that holds the =
center electrode into the insulator.=C2=A0 With extended blasting the =
cement erodes and a well develops around the center electrode.=C2=A0 Not =

process to blast 14 plugs completely without doing some initial carbon =
removal), I first use Hoppe=E2=80=99s #9.=C2=A0 Just set the plugs =
upside down in a rack and drop in enough Hoppe=E2=80=99s to fill the =
plug interior.=C2=A0 Wait an hour (15 minutes is actually enough most =
times), dump out the Hoppe=E2=80=99s, and =C2=A0spray carb cleaner or =
Brakleen into the plug to get much of the carbon out.=C2=A0 Then blow =
dry, and then blast.=C2=A0 Speeds up the process immensely, especially =

tool that=E2=80=99s like a tiny curved saw blade, made to fit=C2=A0 into =
a vibrating engraver-type tool.=C2=A0 That makes fast work of the excess =
carbon around the outside.=C2=A0 Carbon on the center insulator usually =

plugs is to check the resistance.=C2=A0 There=E2=80=99s a resistor in =
virtually every modern aircraft plug, not for RF suppression but for =
good running.=C2=A0 If the resistance decreases (it can over time) the =
plug will develop a misfire.=C2=A0 RF suppression is handled by =
shielding of the magnetos, cables, and the plugs themselves, which have =
a heavy steel outer case.=C2=A0 You never even see the ceramic outside =

which are increasingly rare).<o:p></o:p></span></p><p =

electrode.=C2=A0 The side electrodes can be bent in and out to set the =
gap.=C2=A0 While plug inspection and cleaning is part of every 100-hour =
and annual inspection, blasting can in time round off the edges of the =
electrodes and make the plugs less efficient, as the primary area for =
sparking to begin is at the sharp edges.=C2=A0 I=E2=80=99ve taken an =
ignition file to the tops of my electrodes a few times on older plugs to =
