just popped out the screen on hedge trimmers and it's covered with carbon (looks like a soft tar and seeing this got me wondering if have other issues, mix is off). anyway, make is a tanaka, gets used plenty, nice piece and plan to get it clean it up tonite, gotta get some work in for now while the weather looking good so for now just wanted to ask if or what would work good to get, this carbon, soft tar build up to dissolve somewhat. is there a solution to soak it in, like degreaser, alcohol that might have laying around etc. don't have think i have any de-carbonizer product on hand so for now could get it to a point that can use a wire brush on it. thanks will check back later.
