yeah, before the "who care's about scratches" mob comes at you, I'll let you know what i do.
First off, yes, they are inevitable and I don't blame any who say to embrace them. After all, you gotta enjoy the watch. Worrying about scratches definitely takes the fun out of it.
That said, why not do you best to avoid them. I don't use any "old toothbrush" i have laying around. Along with veraet watch spray and some dish soap, I use an ultra soft infant tooth brush on brushed surfaces, and I use a silicone infant tooth brush on the polished parts. It works great, and i find the silicone toothbrush to be the best way to deep clean without getting any swirlies.
These would do the trick.
