Best patio cleaner?

[Butterfly44]

Wanting to pressure wash my patio. What cleaner would work with my patio pictured? Novice, just bought a second hand karcher and first time doing it.

I'd like to know that too. I tried to Karcher mine but although it worked the loss of grout was a pain in the back side.

We tried pressure washing ours. It it didn’t clean it much because it es so ingrained. Tried bleach too which didn’t work. I’d like to know what would work

There is a product called wet and forget which always gets rave reviews for patio cleaning, I have never used it myself but am going to get some this weekend. We had ours professionally cleaned last year when I had no luck with my own pressure washer. The guy used something on it that killed black spot as well as the normal algae and general dirt that seems to cling to patios. He did a fab job and it looked really clean. It’s not too bad a year later so I’m hoping to be able to spruce it up myself. I think you may need a helping hand with some use of a cleaning product rather than just water pressure. Good luck.
