If a typical spray bottle with DI water and a drop of dish soap doesn't do it, try changing your towel out for newspaper. Works great on cars so probably worth a try. If that fails, then continue using that for cleaning and use a microfiber towel with a gloss spray. Can't remember what gloss spray I use on the bike but I got it FAR at Menards quite some time ago.
