How to clean your Apple Watch - Apple Support

says

"For Solo Loop, Sport Band, and Nike Sport Band:

1. Wipe the band clean with a nonabrasive, lint-free cloth. If necessary, lightly dampen the cloth with fresh water. With these bands, you can also use mild hypoallergenic hand soap for cleaning.
2. Dry the band with a nonabrasive, lint-free cloth before you attach it to your Apple Watch."

You're welcome! Thanks for your reply.

Apple don't seem to recommend anything stronger.
