How do I clean canvas pieces once they have been installed?

You can use a soft cloth or feather duster to clean your canvas art. 

It is not recommended that you use harsh chemicals, cleaners, or abrasive cloths on canvas because their use could cause damage to the substrate. However diluted cleaning solutions or disinfectant wipes are acceptable. 

It is also recommended that you avoid working with sharp objects near or around the canvas, in order to avoid accidentally ripping, tearing, or puncturing the canvas.
