You need a laundry system such as Reshoevn8r. really just the bag(s), shoe trees and a soft/medium bristle brush. Oxyclean laundry detergent and oxyclean max force gel spray. Clean the section with the soft and medium bristle brush. Just enough to get whatever shoe cleaner or even dawn power wash into the fabric and into the dirt/stain. Leave it in there, don’t wash it out. Add oxyclean max force gel and leave in there for a minimum of 24 hours. After 24 hours, throw into the washer inside a bag with a shoe tree and wash on cold. Let fully dry and inspect. Might need one more wash. If so, just rinse and repeat.
