Here is a picture of three so-called commercial-grade 3/4 inch garden hoses. The one in the center is the oldest, a 10 year old Swan. The next oldest is on the bottom (or left, depending on how the picture is rotated); it's an Apex that's about six years old. And the heavily mildewed one on the top (or right) is a three year old Swan.
It's really interesting to me that the oldest hose is nearly free from mildew stains, while the newest one is nearly black. My guess is the newer the hose, the greater the recycled rubber content.
Another annoying thing about the newest hose is it has aluminum ends. These tend to corrode when you connect them to a hose with brass fittings. Other than cost, I can't think of any reason Swan switched from brass to aluminum.
