Barnacle rash removal

[Halo]

Just hauled out and after pressure washing there are a few rashes of small white barnacle remains. Like a tiny thin white patch left by each one. Any tips on easy removal of these?

Leave them to dry out for as long as you can. They then become friable and can be brushed off.

Brick acid from B&Q or a builders merchant, which is based on hydrochloric acid (Hcl). Don't splash it on yourself. Leave to fizz, then rinse off and scrape back.

Wear safety goggles, gloves and disposable overalls. That stuff stings. It also eats your clothes if you give it half a chance.

When I used to get barnacles, I found that they scraped off very easily if they were still wet. If you left them to take off later when dry, they left circular marks.
If working between tides, that is the only option.
