What i've been fighting with recently on this Saturn project is the carbon buildup
on these pistons.
I've been trying to clean the carbon off,
I tried using the old piston rings to scrape out the grooves.
I tried using
break cleaner, carburetor cleaner.
I bought this Berryman B-12 because it says it removes carbon so I
thought maybe if I soaked it in there it would soften it.
It didn't,
I soaked a piston and there for upwards of a week week and it
didn't seem to make any difference. The carbon was still hard and I couldn't get
it off.
So I got this,
it cost about $30.
It says,
"the good stuff"
so maybe that means that it's going to do the job.
On the can here
it says...
carbon residue on valves pistons and other engine parts may require longer
cleaning times.
So, to me that means it's made to do this job.
It's even got a picture of a piston and a valve
and all that good stuff.
So I'm going to give this a shot and hopefully
It will work out make a move on with this project.
Everything I've read says this is some pretty nasty stuff.
A friend of mine who used some said to do it outside.
I've got my goggles on.
Well, it has a
basket in it...
for dipping small parts.
I guess what I'm going to do is that this
piston which I already did quite a bit of manual cleaning on
and see if it can get the residual carbon out of the
piston ring grooves I wasn't able to get.
Ok, it's been in here for a roughly half an hour
right now.
So i can see
it did remove the carbon that was around there.
I can see inside ring grooves, they do
cleaner.
I still see some carbon deposits but lets rinse it and dip it.
This is just water.

Well,
the middle groove which is the one i was having trouble with is looking better.
It's still got some junk in it.
Let me see
if the carbon is softer now.
I'm going
to get a piston ring and see if I can scrap that carbon any easier than before.
I've rinsed this thoroughly with water
so now i'm taking a
piece of a piston ring and I'm trying to
scrape in this groove.
You can see the carbon has turned soft and its peeling up out of there.
So it's actually coming out.
It I soak it longer I bet it
would all dissolve.
I just did some more scraping and
I got some more of it to peel out of there.
I'm almost down to the bottom
so it seems like this stuff is working.
It softens up the top layer
to where I can scrap it off down to harness again
and put it back in to soak longer and it will
soften the next layer.
I'm going to put it back in.
Probably if I just let it soak for hours
it would probably clean the whole thing
off without scraping.
Well I put it back in there and forgot it for about an hour and a half.
It looks pretty good, I can see a few small spots in
some of the grooves that need to
be scraped out but i'm willing to bet they're pretty darn soft and they'll probably come
out really easy.
So all in all this product seems to work really good. I had tried
quite a few different products before it
and didn't get any results at all.
This one, it obviously dissolves carbon
and it does a pretty good job it.
