Removing ANY stain from suede can be tricky, especially if the suede is a lighter color. My particular pieces of suede were not dyed to have the suede a different color, it was natural colored. I have NOT tested this with a colored suede.
The suede I was working with came from a leather purse that I deconstructed to harvest the leather from to make another project. Being the inside of a purse, it had been stained a lot by someone who had clearly never known that pens have CAPS to keep them from writing or leaking inside of your purse! I got the purse from Goodwill for the express purpose of being able to deconstruct it and use it in a different project, so its appearance did not bother me, as I knew I would be cleaning it before I used it for something else.
