removing black mold from canvas

We have a canvas cover over a yurt that has a lot of black mold on it. Does anyone know a good way to remove the mold from the canvas without harmful chemicals?

ive killed mold with a solution made with hot water, boric acid powder, vinegar it also works with hot water, boric acid powder, hydrogen peroxide.
about a gallon of water with a cup or more boric acid powder and a cup or more vinegar or peroxide
worked great for molded wood used in a building I put up, mold hasn't come back 12 years since first application.
I just mopped it on and let it dry.

A previous discussion on the topic of controlling and eliminating mold:

One option that seems to be fairly non-toxic and long-acting is a commercial product called Concrobium

But there are inexpensive homebrew concoctions modeled after it and are said to work.

Thank you for your replies Bruce and Douglas!

I’ve had good luck hitting the mold twice a few hours apart instead of trying to nuke it in one go. The first round loosens things up, the second round actually clears it. I also rinse with plain hot water after everything dries so there’s no leftover residue that might stiffen the canvas. Keeping the cover aired out for a full day made a huge difference for me.
