Is it even possible keep the logo clean on the floor mats?

AKA Why would the Fuji execs use white thread on a floor mat?

Ive tried Resolve and it is hilariously ineffective. Have any of you guys tried full-on steam cleaning?

 

Diluted RIT dye in a syringe/dropper and a wetvac to finish it off.
After you can use a silicon waterproofer absorbed into the threads to prevent dirt buildup for a while

 

I am going after "keeping them clean". I bought a set of mats which are very close to NOS. I am going to try to keep them nice. I bought a Scotchguard product called "Rug & Carpet Protector", 17 oz spray can, blue and white. Got it at Lowes. Have no idea if it is effective, just got it.
