Galvalume water spots

Return to Installation

Return to Forum

Just took delivery of panels and some panels exhibit white discoloration from water (I guess). Some are quarter size and there are some that are 3x24. The panels definitely got very wet prior to receiving (was dry when delivered).

I was advised to try a pressure washer with detergent. It was not effective to remove the stain.

I used some wd40 with light pressure and wiped clean with denatured alcohol. This seems to work. Does this method of removing the spots risk the finish?

With that being said I am also a little concerned when the warranty states:

"Failure to keep condensation or moisture from nested materials may result in damage or wet storage stain, voiding seller’s warranty."

Thank you for posting. Because this concerns potential warranty issues, I really must suggest you contact the manufacturer of the panels as they are the only ones who can make that determination.
