Thank you. Just a piece of advice on your Karcher pressure washer. You are using attachment that was designed to remove heavy dirt from construction equipment. Usually rotating jet streams are designed to do that. Here in USA we can buy attachments that come 10,20,30,45 degrees (come in white, yellow, red color) and also 0 degrees for application of soap. Best to have used here would have been 10-30 degrees and it would have given a triangle stream uniform which would allow you to just wave it over the rocks in a pattern.
