High-pressure cleaner, but which one?

Did not mean these "Ufos" but brushes that are mounted on a carrier or tractor. What also works well are the joint attachments that can be used with brush cutters.

I like this forum^^ Many opinions when you need them and at the same time the support :)

I really wanted to restore the stones to factory condition with a high-pressure cleaner, but the experience of some colleagues here changes my perspective. A pressure washer is probably not the solution.

You have convinced me that I will resort to scrubbing. The risk that I will damage the new stones or slabs is high.^^

Oh, are you already that far with your house? - that’s nice. But as you say yourself ...

My to-do list is long and getting longer :) Especially since management holds the longer lever...

Scrubbing is good for the muscles, metabolism, and with a fast pace, it replaces cardio training.

I need that ... :D

I simply advertised for good old scrubbing.

My to-do list is long and keeps getting longer

Does that mean you are still not that far along, and you just have a bunch of todos to tackle? Or are you even slow, and the moss is growing in the gaps of the to-do list?

But besides baking soda/soap/yeast and scrubbing manually with a brush, are there any other alternatives? Probably not? Is the mechanical stress of scrubbing really gentler on the stones than the pressure washer? I can't quite imagine that.

Driveway, sidewalk, outside, scrubbing?:D:oops: When I was young, about 5 years ago, people swept with the broom with the red bristles for 5 €. Insider tip, give it a try.;)
