Today I took the canvases off of the warp and cloth beams. These were tacked on and came off fairly easily using a small flat screw driver, a lot of pressure to insert it under the head and prying gently and slowly. Both canvases were very dirty…an indication that it had been neglected in a dirty area. At first I used a gentle soap in cold water on delicate cycle; the canvas was in a mesh bag. It came out dirty. So I used Tide on cold water, and a regular cycle. This cleaned them well and then I stretched them by hand and hung them to dry. This was more than satisfactory.
