I brought out my summer sandals and found that the suede insoles were very soiled looking. See below.
I remembered my mother saying that you could clean suede with sandpaper. I thought, 'Wow, that's weird' and it stuck in my head. So I tried it!
Guess what? It WORKS!!
Has anyone ever tried this?
I think it will work on any brushed leather (suede)... but be careful when trying this... try an inconspicuous place first. In my case, it didn't matter because I was ready to throw these sandals out. So whether I ruined them, it didn't matter. But it worked!!! YAY!
