chaim: I've cleaned the glass 3 or 4 different ways, can you suggest a preferred way of cleaning it?

Clean the glass on both sides (both pieces) with a lint-free cloth. Also vacuum the innards of the enlarger - both above and below the negative holder. The dust problem is difficult to solve... Also, handle the negatives with cotton gloves, perhaps wiping them softly before inserting into the neg. carrier.
I know I also have problems with dust :-(((
