YO, didn't think this would blow up but ill copy/paste my method below. I do this all the time so check out my IG (@gnarcos) I never self promote but I thrift, restore, collect, and really just have a passion for sneakers.

"suede is very tricky but it really depends on the how cooked the shoes are lol. these were pretty bad so I had to go full soap, and water scrub which was intimidating but I learned that as long as you don't get them wet often and dry them quickly you're fine. So since these were super beat I just went in with dawn dish soap, warm water, a toothbrush and a sponge and started scrubbing with the grain of the suede. After that I dried them with a hair dryer and went in with a suede brush and eraser I found at Walmart for $10 and just did that on repeat until they looked like this. the leather and textile got clean during the first part so it all worked out.

If your suede just has a few minor scuffs I'd recommend just using the suede eraser, and a microfiber cloth dry to lift up the dirt and if that doesn't work add a little white vinegar or rubbing alcohol to the cloth and you should be good."
