This is the same piston after soaking the rest of the day in EDTA and giving a quick wipe with some crumpled up paper. What's left comes off with your fingernail. No visible corrosion.
I put the piston in my 1050 to TDC and poured in some of the solution, put the plug in it, and then swirled it around and tipped it plug hole down to keep it from getting into the crankcase. I also wadded up some cloth and jammed it in the exhaust port, and then poured the solution on the cloth to keep the carbon exposed to the solution without having to flood the saw.
I don't mind using those carbon cleaning fuel additive and carb sprays on 4 strokes. I don't like the idea of running them through a two stroke though.
I'm not trying to get an assembled saw spotless. I just want to get it removed enough where it will self clean without the risk of damage from a big chunk breaking loose once you start using a clean burning modern mix.
Pulling it all apart to clean if you have one saw isn't a big deal. But I have 40 plus project saws.
