How to get rid of green tint on wooden swing set? - used wooden swing set

We get a swing for over 10 years used. Still in great shape, very well built. However, he had been in the shade under the trees and the wood has a green color to them. Almost like a moss or mildew. This is not something you scrape, but the wood was actually paint. Someone said, rub the bleach mixture of water and sit in the sun for a few days? Any recommendations? Point plan and grinding it with a kind of sealing. Any ideas on this?
