If you use high-grade Alcohol, you don't have streak issues. MEK is a very capable solvent (some people use it to glue/weld plastic). I wouldn't use that kind of stuff unless the manufacturer tells me to explicitly. It's much more dangerous than Ethanol or Isopropanol and more complicated to get. Start with 99.9% Isopropanol. You can get it cheap in lab grade from ebay.

You can buy MEK at Home Depot and other paint stores. Diluted properly with the alcohol it's harmless to optics. BY itself, that is another story.

Hi again, finally we have installed the exhaust that you recommended Mark.
Now it really makes sense to clean the prism. Is it actually necessary to have that base plate in place NEC recommends before you start?

IDK what baseplate you are talking about. The light engine is removable as a unit in it's frame assembly. The picture is what you pull out. This was the one and only bad NC-2000 engine I ever had to replace, and the bad pixels were caused by demolition work going on right next to the projector. Once it's pulled I usually set them down on a clean work surface covered with a cloth.
