Cleaning the strap
My watch strap is looking a little worse for wear, is it possible to clean it?
Yes, it is indeed. First, you'll want to dab the watch strap all over with a damp (not wet) cloth. Now put a small amount of soap on the cloth and lightly scrub the strap.
Next up, rinse the cloth until clean and soapless, dampen it once more and wipe the strap clean. Then you'll want to completely dry the strap and then leave it to air dry.
This may not remove all marks and stains but it should go some way to freshening up your strap.
