1.   These stains will never come out!

2.   A week later, thanks to the Yankees, the season was over and Rangers management was wondering where all the champagne stains came from.

3.   A. There is no reason that I know of not to power wash, especially if the stain is coming up that easily.

4.   But the stains came back, and fibers started falling out.

5.   If the stain comes clean, then seal the grout with a masonry sealer or tile sealer.

6.   In a hospital or other medical center, the stain might come from a substance that requires a more potent cleaning with alcohol or antibacterial soap.

7.   Such stains come in earth colors.

8.   That is where stains come into the picture.

9.   The stain comes off easily by washing with a hose, but I was told not to power wash.

10.   We applied a coat of stain killer before painting over this mildew, but the mildew stains came back in less than one year.
