Magic of Pressure Washers

Our trellis fence has been up for 27 years, still going strong. It does get green at times, especially to the North facing side of the garden. When that happens it's time to get out our old Karcher pressure washer and give it a good, but gentle, blasting! Marlane did the blasting while I cut the bit of lawn we have left.

The wood was initially painted with 'Ducks Back' Cedar Red paint, which contains a lot of wax. I think that has contributed to the longevity of the trellis.
