The tramp in question. it's about 4 years old, blue,poly.,mesh. It has about 1 1/2 years of sun and oxidation. slight fading.

Is there trick to at minimum making it look better. I was thinking of srubbing it with "comet" or a like product.

Is there a better product?

Any Suggestions?

replacement is not an option right now. cause it would be custom and its approx 14ft square. And I'm broke.
