Off Topic Hull cleaning

[Bentrod]

I am sure many on this forum care about their boats. I have been looking for a way to clean the brownish colour off my boat’s hull and wanted to share a product I found that worked really well. It is Spray Nine with Oxalic acid, Phosphoric acid and Ethoxylated alcohol, pictures attached. It is like a gel, I put about 300ml in a bucket, put a rug in and applied on the hull, wait for a couple minutes and then rinse off. The first picture shows how well it worked. The 300ml wa enough for my 18’ Bayliner. I got it at Canadian Tire for $16.99. Hope this helps.

Thanks for the tip @Bentrod. I will try it on that stubborn Catfish Creek scum that's so difficult to remove.
