Sun hatch frame cleaning

[VitaminR]

I am looking for a method to clean my sun hatch frame the cleaners I’ve tried have not worked. I’ve tried deck bright, FSR and baking soda , soft scrub and white vinegar. Still has dark pitted stains.
Please tell me there is a solution for this ?

We had the same issue, we could not get the hatches clean. Found out the dark stains are mildew, get a mildew cleaner and apply that, a little scrubbing, a lot of rinsing. May need a couple of applications. Ours are white again!

Try a watered down bleach/water solution. Sprayed on and let it sit for a little bit. Work great for me. Just make sure you put a towel down so any of the residual bleach water solution doesn’t leak anything else

On my hatch frames I use RMR-86M mildew and stain remover. In minutes it removes the stains with little scrubbing.
