mold on canvas

(Mold Armor) Can be found @ Home Depot and many others. I can assure you that when you spray it on the mold will roll off.

When u say mild soap,do you mean dish soap or laundry?

If you go the vinegar route, make sure it is the white kind, and only try it on a very small area as vinegar is a very very weak acid.

Thanks,has anyone heard of using vinegar and water

If the canvas is heavily stained, you are stuck with it. Just clean with mild soap and water, DRY thoroughly then spray on one of those waterproof spray products for canvas. let that dry and repeat spray again. Then remember, NEVER store any canvas wet, or even damp, and you should be good to go.
