Ha, ironic timing.
I had a 2x6 glued to a plywood sheet, which served as a bed box-spring support.
Well, re-made the kid’s beds and no longer need that ply support. I wanted to re-use the sheet for some shop storage stuff.
So, this past Sunday I cut and knocked the 2x6 off, leaving a straggly wandering glue line, 5” wide by about 45” long. Used the RO90 and Granat 100 to clean that off. Came the same conclusions: Granat didn’t load up at all with any glue and took it down very readily. The only (very minor) negative is that I must’ve hit a glue peak or edge, which tore the very edge of the paper disc.
Good stuff!
