"30 Second Cleaner" on exterior clear coat

[FOILED]

I have green stuff along my seams, caulking and windows after winter storage. Small amounts still remain after washing with Maguire's car detergent. I don't want to damage my clear coat. Does anyone have experience using "30 Seconds Outdoor Cleaner" (it has 5% bleach) to spray onto the AS followed by a quick rinse?

I've found that a soft brush with regular old car wash soap works. You just need to get into the nooks and crannies that the sponge doesn't get.
