Add to the Sunshine cloth Veraet Watch Spray, a gentle watch cleaner. It actually cleans better than soap and water, and leaves no residue. Although I used a gentle soap for years on my SuperOcean, apparently the residue from the soap can over time seep into the seals, even though I didn't have a problem.
http://www.veraet.com/The Sunshine cloths are wonderful as well every so often, then a wash with Veraet. I have never tried the Cape Cod cloths, but I believe they are more for getting out scratches.

I will have a look at Veraet. Thank you for the heads up. I, like you, have never used Cape Cod. My understanding is the same as yours on this product and I am much happier looking for anything that is gentle.
