Not to beat up an old topic but

[swedenwatch]

I was wondering what is a more effective way to clean a rolex band, ultra sonic cleaning, or using a brush and soap or that vareate watch spray?

I know everyone has there own opinions my goal here is to clean to avoid the wear aka "stretch" of the band, I know to fix it it is not a big deal $150 or so, but avoiding it would be ideal.

I took the watch for an ultrasonic cleaning at my local AD today and I still notice dark grime between the links, he did it for what seemed like 5minutes so not sure if it wasnt long enough or maybe not done properly.

Any recommendations would be great, thanks guys!
