Re: How to CLEAN N.O.S. Fan Shroud ?????
Like Stefano, I quite routinely use media or glass and blast my shrouds. I use low pressure and start in an out of the way place until I get the pressure just right. I also use this on air conditioning dog houses with very little if any ill effect of the plastic.
I would not suggest this on a part being resold as an NOS but have no problem on a NOS piece destined for a restoration I am doing.
