Hello
I have a Karcher k7
I also have a brush adaptable to the nozzle. Can I use it to remove moss from my slate roof?
If not Is there a tool to plug into the nozzle to remove the foam?
Hello,
It is not recommended to use a pressure washer on a slate roof as this may damage the tiles.
There are gentle cleaning attachments for pressure washers, but the safest option is to use a specific anti-foam treatment and let the foam come off naturally.
Have a nice day!
