Chuck - just did some poking around the internet to see if mineral spirits damage rubber. As far as I can tell, mineral spirits can damage rubber, but it depends on how long they're contacting the rubber, and what type of rubber it is.
One of the reasons I asked is I bought some used equipment with spraypaint on it once. I bought some spraypaint remover to take it off. Some minutes later, I lightly scraped a screwdriver over the paint, to see if it would flake off. To my surprise, the screwdriver dragged a shallow ditch on the surface of some plastic parts of the equipment. The paint remover had literally turned plastic into a semi-soft gel.
So I'm still a little concerned about using mineral spirits on the rollers of the DW735. Wouldn't want sticky glue removal to spiral into a bigger/more expensive problem.
Maybe I'll contact Dewalt an see what they recommend - unless you and others have some anecdotal info about personally using mineral spirits on the DW735 without any issues
