Got some parts off well used pulp saws.
pine pitch was left on from day one and built up plenty thick.
downright NASTY !!
heres a pic of one showing the black built up gunk that had also made it's way into the inside along with the usuall buildup that get's there..

i had three of these starters to do so i experimented with one and it came out so good i did the other two..
after cleaning the outside of the first one i turned it over and cleaned the inside..
that worked so well i did the other two both sides at the same time and it worked well.
i cleaned these outside below freezing..
all thats needed is warm water and a soft brush to get all the gunk off and leave the plastic looking like new..
i took the insides apart to clean the starter spring and parts too ..
Im talking NO work cleaning here,spray it on and water and brush it off.
i found letting it sit on a couple hours or more was no problem..
here are the parts.
rinsed and dried.
No polishing or anything !!

didnt bother the logo at all.
even the soft white plastic recoil spring holders came out clean and nice.
i found the same thing cheaper at the box stores instead of the grocery store.
use OUTSIDE !!
dont breath it.
wash hands after..


I dont know how it would work on Stheal plastic,it may be to cheap and soft and melt..

Just be damn sure you don't get any of that oven cleaner (including residue) on your mag or aluminum parts. Corrosion city....

Will turn alumnium a little bit.

I use it to clean mag to get the oil out for painting,dont bother it a bit..

heres a mag cover i did with the oven cleaner to prep it.

no corrosion,no problem..
of course,rinsing is important with ANY cleaner.

Does that cleaner have lye in it?
 
I read it too....

I was hoping it was good enough to turn that husky into a Stihl.....that would be impressive ...hehe....sorry Ron I know how much you don't love Stihls....

Oh snap I just saw it did change it into a Stihl ....darn that's good stuff !!!!



:cry: maybe if i turn the can upside down it will work the other way !!

LOL !!!!!!
 
Great info Ron, I had Mary pick me up a couple cans of it tonight when she went to town. I'll be trying it out on my 268xp to 272xp conversion.:rock:
 
We have used Easy Off to clean carbon off aluminum pistons forever, cleaned nasty chainsaws with it since I was a kid, takes off most of that black exhaust staining from chainsaw bar mount areas also.
Thanks for posting ,Ron.

Good stuff, you know we gotta do that now......I'm going to the Dollar Store. :laugh:

Hey Randy !!

well,,,maybe you dont,,,,,,,,not pretty....wouldnt recomend it unlees you like dark grey !! ??

may take pix of jug results tomorrow,some may like it ??
 

Ron, sodium hydroxide is lye. I've seen oven cleaners with and without lye.

fourth paragraph said:
Sodium Hydroxide
You know that scene in Fight Club where Brad Pitt explains what happens when you mix lye with melted animal grease? That's exactly what happens when you spray this stuff into your oven. Butane and MEA soften the hard organic coating, allowing the sodium hydroxide to attack the underlying fatty triglyceride molecules. That reaction gives off heat and results in a simple form of soap. Incidentally, don't use Easy-Off on aluminum — the metal serves as a room-temperature catalyst, breaking down the NaOH and releasing flammable hydrogen gas.

Sodium hydroxide - Wikipedia, the free encyclopedia
 

Actually, if you read your link, it says it does have sodium hydroxide in it. That's lye. Same active ingredient in 'Purple Power' type cleaners.

I got some pine sap all over one saw - someone suggested that I use rubbing alcohol to get it off. Looks like there is some alcohol in that mix too!
