Yellowing mold release

Purchased a new boat last year and now starting to get yellowing on the non skid.

Think it is mold release.

what is the least aggressive way to address this ?

thanks so much for the input !!!

 

Depends on the texture, mold release agent

We need pictures.

Why do you think it's the release agent.

 

I'd consider a detergent solution and a brush with nylon bristles.I don't doubt that many would recommend a pressure washer,but that might force high pressure water through any gaps in bedding compound beneath the deck hardware and perhaps into any core beneath the surface.

 

Sorry need to take photos. The mold release was just an assumption and could be wrong. Best way to describe it is a slightly darker area in the non skid that does not seem to wash with soap and water

thanks
