Then treat with Wet n Forget or similar decking or patio treatment will stop it coming straight back

A portable steam cleaner jet nozzle is excellent for this task I have an appointment with my boat for this process shortly !

1 1/2 inch paint brush,( a cheepo stiffish one stipled into the grooves) some brick cleaner. Followed by a good flush with soapy water. Remove interior upholstery first.

I use it on my gunwhale & can see no issues. But I do wash it off fairly quickly, as it displaces the moss very fast. The stuff I use is 50 year old commercial from my building days. It is a lot stronger than current brick cleaner, I know it is when I compare it with modern stuff when cleaning my prop, so if that does no harm I cannot see a problem.
