What’s the best way to clean white plastic yard chairs after storage over the winter?

I have small black spots on the arms and seats of my plastic yard chairs and I am finding them to be difficult to remove. I don’t want to use anything too abrasive for fear it would ruin the smooth surface. Does anyone know of a product that would work or even a home made cleaning solvent?
I would appreciate any suggestions. Thanks

Mix 1 cup of bleach, 1cup of tide and 1 cup of Spic and Span. Add it to two gallons of warm water and use it with a brush. It takes it right off. Rinse well.
try clorox clean up it cleans just about anything
Try putting some bleach in the water to clean it. Also Ajax or some type of cleaner with a little abrassiveness will work.
I have used Brillo pads on mine and it didn’t seem to hurt it. But, then again, my chair is old and I really didn’t care if it did. I didn’t scrub real hard, just more or less used the soap from the Brillo pad. I don’t know what type of detergent is in the Brillo pads, but it works on a lot of things. Also, Dawn dishwashing liquid cleans a lot of things really well.
try a magic eraser, it takes off everything else!
