Swirl marks don't come from cleaning the lenses, scratches may come from frequent cleaning but swirl marks don't. Therefore, if you feel you are definitely seeing swirl marks, visit the eyewear facility that you purchased them from and be sure that an Optician in the lab or retail looks at the lens thoroughly. If swirl marks are found, the lenses should not have passed quality inspection, therefore must be redone. Real swirl marks come from lens manufacture and shouldn’t ever be there.

The replacements are now starting to develop them too. I haven't had this happen to any other pair I've ever owned. I'm starting to think the materials used are not what I paid for. Though I do use dish soap and water as I find it does the best job of cleaning off smudges and reduces glare (except for the swirls). Perhaps I'm cleaning off the polishing that was hiding the marks in the first place. But like I said, I've always used the dish soap and water method for all my prescription lenses with no problems.
