How do you clean stains on Trex decking ?

I have Trex decking on my back porch. Over the years it has accumulated stains from spilled butter and stains from flower pot s. If I turn up the power washer up to high it will gouge the surface

    My husband uses bleach and water to clean our Trex decking. He mixes it in a bucket and then mops it onto the deck. He hoses the deck with water afterwards.
