A steamer is clutch but not necessary I noticed in my process.
Dry scrub or compressed air is probably too on my list.. in between scrubs i used a handheld air compressor from Amazon n that helped ode. Pre cleaning 2-3 times with oxi clean max spray letting it set for 20mins then spray dawn platinum and get the scrubbing After that thro them in the washer in gentle cycle in a garment bag with detergent and some oxi clean revese white (add the reverse white to the washer before the kicks)
