The stains are darker than the concrete, Stains don't seem to be grease. I used a de-greaser, clorax bleach and dawn detergent. Help!

I've used baking soda in the past and it's worked fairly well. This site has some ideas that I wouldn't have thought of: https://www.rd.com/home/cleaning-organizing/cleaning-concrete-stains/
try hydrogen peroxide
They may be Rust.
I would use a Rust remover and be aware of the run off when rinsing it.
If this doesn’t work, a mild muriatic acid solution will. Being acid, wear PPE and practice acid-mixing safety.
Mix 1/2 cup baking soda to one gallon of water for a gentle cleaning solution. Add 1/8 cup of liquid dish detergent. Spray on patio surface, let sit for 30 minutes, then scrub and rinse. For heavily stained or mildewed patios, you may need a pressure washer.
you will need to use either an hammer or an compressor hammer
