Cleaning the boat with acid. We tried a lot of way to clean the yellow surface in the cockpit. Nothing worked. Until one of the viewers advised oxalic acid. You can buy this a rust remover bit you also can buy this at the professional garden shop. It is used for cleaning and bee-keeping. And also for wood with stains.
I bought is to clean the engine, but we tried it on the free boat too. Watch the miracle.
