Streaks on patio

I cleaned my back patio with a pressure washer today.
As you can see, there are streaks on the patio. Does anybody know what it is and how to get it off?

Thanks,

Those marks are from it being covered with polyurethane after it was finished. Most times it’s done to protect the concrete from rain before it cures. The marks are in the concrete and I don’t know of a way to remove them.

It seems sealing is the only solution to this.
Thank you

Sealing will not remove those streaks.

I wonder if using a colored or tinted sealer would help hide them a little? I’ve never used one so not sure.

As mentioned sealer won’t do anything. Might hide it a bit when it’s dry but will look more or less the same when it’s wet. Being your own patio, why not just paint it. Most of these concrete paints dry to a Matte finish, look like fresh concrete and super durable, soft wash it once a year and your golden. Plenty of colors and options out there

You might be able to acid etch it then repeat it with a solid sealer.
