My sprinkler system leaves white limescale mark on my fence (California redwood). How can I remove limesvale marks.
I tried soda with limited results.. Still very hard to remove. I tried water ressure but it damages the wood,
Any idea?

I don't know about how it would work on wood, but I use vinegar in my bathroom and in my tea kettle to remove the limescale. You might have to leave it on for a bit and try scrubbing, but it might work.

Try Lime-A-Way, available at most big box stores. This will also slow the development of future lime.

Use the weakest nozzle on pressure washer and stand back enough so that it is just a rinse.
