I have a very nice engine that has some varnish cooked onto the head, and wonder what the best way is to remove it without damaging the fins. A very long time ago, I remember helping a friend clean up one of his engines, and the stuff we used was really foul smelling. Any suggestions? Thanks
Lye or anything (caustic) with it as a part of the mix will cause alum. to turn grey if exposed long enough.
Once cleaned or better yet, I do all my new engines with this ** and they remain most like new.
Place the engine and muffler in a baggie and spray enough ** into the baggie to create a thin fog.
Then seal the baggie and let set for a half hour or so. Repeat one more time and reseal untill use.
I repeat treatment as needed, when needed. I go spring and fall !
**
Liquid Wrench® Heavy Duty Silicone Lubricant (M914)
Item no: 80876
or
Ace Pure Silicone Lubriacant
Item no: 12293
both are 11 oz. and a
General purpose aerosol lubricant.
Stops squeaks, rust and corrosion.
Protects aluminum and chrome.
Contains no chlorinated solvents.
Once pretreated you will find that the castor crud is much more easily and faster removed with Hot Water and Dawn PC (I use Dawn Dish Soap). Do Not breathe any of these fumes.......[

Harder Spot cleanup can be done with acetone or MEK....when using this pretreatment.
Do Not fail to wash hands before touching face or eating after using any silicone product.
