Engine Painting Prep

[Rich1972C20]

I got my engine back from the my machine shop and I would like to paint it. I was watching UTG (Uncle Tony's Garage) and he showed using a MAP burner to sweat out the oils\contaminants before painting. Sure enough my engine is sweating out contaminants, but I've gone through a bottle already with no end in sight.

Is this normal its taking this much gas or am I doing something wrong/overboard?

I normally use a good quality brake cleaner or starting fluid.

That pulls the oil out from the porous cast iron.

Make sure whatever process used, That it is in a well-ventilated area.

Also have a fire extinguisher around.

All I have ever done is wash with simple green. Let dry for couple days and spray on good quality paint like VHT. Never had any issues. I would not use a torch for fear of cooking the gaskets. Especially valve cover.
