My shower enclosure has two wall surfaces which have cultured marble flat sheet marterial. Over the years they have discolored from white to off-white. Is there any way to restore the white color?

I have heard of this problem before but I have never heard of a solution to it.

You could contact any manufacturer of culture marble and ask their engineer. Or post this question to a chemist in one of our other Forums to advise you on this issue.

Let us know what solution worked for you . Thanks. Milo

Milo,

Once again very honest respond, Thanks.

Regards,
John
