Hello, I have white barker board enclosing my tub. I have an artesian well with a high iron content. Over time, the once white barker board has turned to a dull yellow/beige. I intend to replace it next year but in the meantime I am looking for a cheap alternative to brighten it up. Two questions then - First, can barker board be painted and if so what type of paint would you recommend. I have asked this question at various home repair stores and received conflicting responses. Secondly, if painting is not an option, what can I use to brighten it up. I have tried various cleaners without luck. Thank you for any and all suggestions.

 

Sorry for the delay in response, but after extensive searching, I can't find out what "barker board" is. Any clue as to what it might be made of, or maybe a better description of it?

This may be in the "better late than never" category; but after reading the technical data sheet from the barker.ca website I would try washing your barker board with a household bleach and if that removes the yellowing then treat the renewed surface with a good automotive car polish. There is also a cleaner on the market called CLR that removes Calcium, Lime and Rust (hence the name). If you can find that stuff you might try it (diluted because it is strong stuff). Cheers
