Cylinder cleaning.

[StihlEchoingHusky]

Thought I'd pass along information. Although I'm pretty sure a lot of people already do this or know about it.

The drill powered cleaning brushes that can be bought at Lowe's or online. The soft white ones work great. I've been using one of those plus dawn Platinum with hot water for the initial pre porting cleaning.

I feel like my after porting cleaning might be a little bit overkill. I use the garden hose with jet attachment. I have a heavy vise that I've been using to keep the cylinder in place. While I rinse it out. Then hot water with dawn Platinum. I use a little brush that comes with bottle brushes to get into the transfers,spark plug hole and the decompression hole if the cylinder has one. I then take it back outside into the vise and fire up the pressure washer. Typically I'll use a turbo tip. on a few occasions I use the red 0 degree tip. Then I will hit it with a 50/50 purple power/water. I'll use the little brush again then I'll just rinse with hot water for a little while and then I'll pour a little bit of mix gas through it.. similar to how I clean assembled crankcases but without the pressure washer. Instead I use isopropyl alcohol, blow out with air then follow with mix trying to flush out any remaining water. Without the seals in place.

Idk if this is overkill or not but I'd rather get it clean as possible especially if they aren't my saws. I'm to paranoid that some metal grit is going to mess everything up.

Cut a slit in it lengthwise
Makes a mandrel insert your favorite emery cloth
Put in cordless drill
Probably have done at least a hundred cylinder cleanups
All still running as far as i know.

I used to use emery cloth, but now I've gone to using steel wool wrapped around a carbide bur or drill bit to do both pre-porting and after-porting cleaning/polishing.

I've got a few foredom split mandrels. Wo you wouldn't that be the same? Also when I meant clean up I meant for removing shards of metal from porting. Wouldn't Emery cloth produce grit?

I can see that working to remove piston transfer from over heating. But I don't know maybe it does work for grit removal. I've still got so many things to learn. Porting wise I've only got 1 failure. my first saw. I got to power hungry after trenching finger ports. I cut the base... 271 so ya.. needless to say it won't seal currently. maybe if I fiddle farted with gasket material and sealer I might be able to but not really worth it in my opinion. I've got pro saws now and have ported 22 other saws since. Live and learn

Ive been tossing my jugs into an ultra sonic from harbor freight overnite. I use wax n grease remover in it, after the soak I just pour the WnG through a big funnel with a few layers of old T-shirt to filter for reuse. The ultra sonic gets the bits that are caked on and loosens up everything else so that when I give it a final shot n wipe down with brake clean before assembly I got everything off.

But w/e works to get it clean IMO is still clean in the end.
