Green mold removal concrete garage

Due to summer humidity I have a large area of concrete that has gathered some areas of mold. I was thinking of using a weed sprayer I have that the seals will hold up to bleach. Read a ratio of 1 cup bleach to 1 gal water is about right. My question is, I do not intend to scrub or wash down. Way to big of a hassle. I just we wanted to mist the area and let it kill the mold and just dry up on its own. Is this possible without staining the Concrete? Please advise on ratio you think recommended for what I intend on doing. Thx

I use a bleach/water solution often to clean siding and decks prior to repaints. I've always mixed it 40-50% bleach. I've always rinsed well as the bleach solution can eat away at the wood fibers. Not sure how it would act unrinsed on concrete.

Sounds like your looking for an easy no work fix.
If so this product will work.

If it was mine I'd just use my pressure washer with the turbo blaster nozzle.
