Cleaning a concrete patch

Oh dear !
My entire patio needs cleaning.
I use a mixture of Ariel , bleach and hot water - after a big scrub I hose it down.

You can use equal parts of white vinegar and water. Adding bicarbonate of soda will help too. Lots of tips online.
Give it a brush and let it work then wash or power wash. Our patio comes clean with a good power wash.

Power wash it, it will come up pale cream colour.

How about painting the concrete. We have done that on a wall, it looks fine

A hydrogen peroxide based cleaner was mentioned to me. For some reason I was advised not to use a hard broom. Hence looking for advice here!

Patio cleaner and hard broom then a jet wash or hose down.
