maybe slightly off topic but if suede gets a little dirty do i brush the shoe with a baby brush or something before spraying
Suede you need to use a suede brush first. Meltonian (shocker) makes a suede cleaner with a suede brush that you need to clean them with first.
I made the mistake of being overzealous and wearing my RB Suede MBBs without spraying them and driving in them. Fortunately, the Meltonian suede cleaner took the dirt off quickly and then I sprayed them and now they are good. I'm lazy so I don't take my booties off to drive.
Suede needs a stiffer brush than python or watersnake.
