I have run into two houses that have discolored siding. One is a white vinyl that is yellowish near the eves. It seems wherever the sun doesn't hit it for very long it is discolored. I have the same problem with an aluminum sided house, but the discoloration is darker. Have tried bleach mixes and had scrubbed to no success. Thanks for any info.
ps I think both sidings are over 20 years old as well.
