I am replacing the gas springs on my outdoor sun blinds, and have difficulty removing brass pins holding an aluminum lever. The sun blinds are about 16 years old and there is white corrosion visible. Obviously they are exposed to rain, sun and temperature variation.
I can pull the pins out with a makeshift screw-jack but it takes up to twenty minutes per pin. Once removed I can clean the corrosion easily with sandpaper.
Does anyone know a method to remove or soften this corrosion?
