Typically, your canvas will only need a light dusting every now and then. If you should need to spot clean your canvas, use a damp cloth that only has water on it – no cleaners, please!
If you happen to scuff your canvas, we've found that dotting the scuff (not coloring back and fourth) with a color comparable Bic Mark It Marker can help to touch up the spot and make it less noticeable!
Please take care in storing your canvases – anything that leans up against the canvas will "dent" the soft canvas material. If this should happen, no worries! The indent should come out if you liberally douse the back of the canvas with very hot water, and then sit it upright and let it dry. Depending on the depth of the indent, you may need to repeat the process a few times, but it should end up stretched tight like a drum again!
