I'm sure I've seen this topic on here before but can't find it using the search engine. I've got desiccant ball dust in my closed loop caked on the walls. What should I use to clean it off? Ty
You could buy a glass tube and some cans of butane and it would probably cost a lot less than $175 a lb. A closed loop could be as cheap as a few grand all the way on up to tens (or hundreds) of thousands.
