Hello,
I need some help. For each of the following stains (which I have included links to), could you please tell me:
1) what are they
2) what causes them
3) how to remove them
4) how to prevent them
The links to the stain pictures are:
* Black Stain *
* Brown Stain *
* Copper & Unknown Stain * (the blue is copper, the lightest shade is the normal plaster color... it's the darker shade that is not supposed to be there and is unknown)
Thank you in advance for you help and prompt reply.
Michael
