Cleaning canvas question

[goeasy123]

The canvas on my boat has long dead, ingrained mold stains in it. What's the best way to clean it?

I've tried mold remover, all the usual household cleaners including the peroxide base ones. Nothing has shifted it yet.

I'm in Spain. Doubtful I can get P-M. What do we think the active ingredient is so I can look for something similar here?

Our sprayhood and dodgers go in the washing machine on a cool wash. Not sure I would put a new one in, but they are over 10 years old so have shrunk all they every will.
