Here's the boat, sitting on foam blocks, while I clean up the table. Its a lot of work, to get the basement clean enough varnish in. I have done this cleanup before-a long day's work. I vacuum everything that can be vacuumed-corner to corner, edge to edge, walls, floors, water pipes, electrical cables, stairs, etc. Remove contents of shelves, clean & replace. First with the shop vac, then with the household vac. Non-existent dust can't settle on the finish. Its a "pain", but it works.
