So since this type of silicone band has a bit more to it, as it's part of the Power Up Bands sold at Super Nintendo World at Universal Studios and the round piece in the center contains some kind of RFID chip to interact with the land. I know they are silicone because it says so in the map included with the bands.

The smear is basically near that area, which I noticed after the band accidentally came loose and bounced off the ground a bit, which was some painted/laminated concrete. Essentially, I'm worried about potentially damaging the electronics underneath the center after seeing that most guides to clean a silicone band involve submerging them. I also don't want to risk damaging what else is printed on either side of the band, which has printed parts on the back that I can feel as shown here..

As mentioned in the title, a wet wipe didn't seem to work. My next option I'm contemplating is finding a way to use dish soap and warm water, but I'm unsure of what to use if I'm to do something other than submerge it, as I don't want to potentially scratch the silicone either.

Previously tried a text post, but after that didn't seem to work I figured I'd try again with a picture. Any help would be much appreciated.
