anthman Posted October 14, 2020 Share Posted October 14, 2020 Hi guys, i have an aluminium boat (Stabicraft) thats is almost 2 years old. Ive noticed what i can only describe as salt "stains" on the inside (ill upload a photo when i can) through out the inside - almost like bits of salt spray or small splashes that i likely failed to wipe of along time ago. BTW, my cleaning regime does not involves spray everything inside as i have lots of gear in the various storage areas, in case the question is asked. I instead wipe down the surface areas. Im wondering how you all deal with this - id like to spend some time to get rid of it before it gets worse. I was thinking maybe sanding and then polishing with aluminum polish, then some sort of thing protecting coating (wipe down with INOX lanolin?) cheers!

Rebel Posted October 14, 2020 Share Posted October 14, 2020 CRC Marine66. CLR. Hot soapy water. Hope this helps. Good luck. Cheers. Link to comment Share on other sites More sharing options...
M1100S Posted October 15, 2020 Share Posted October 15, 2020 Does it look similar to this...i have some aswell on inside. I wonder is that marine66 safe for nyalic coating?? Link to comment Share on other sites More sharing options...
anthman Posted October 15, 2020 Author Share Posted October 15, 2020 Looks like the marking inside the red circle: Link to comment Share on other sites More sharing options...
kingie chaser Posted October 15, 2020 Share Posted October 15, 2020 Would be good to see your photo but my thought is when you stated you don't like to spray your your internal areas it does have to be treated differently to say a painted surface which I think is a lot easier to deal with. Not sure of the answer but continuous salt spray exposure uncleaned from not hosing down is probably what's done the damage? Maybe just a simple coat of silicone spray will help? I think if it was me I would want to be periodically still spraying down the inside with a salt dispersion agent like saltaway then rince of.

anthman Posted October 15, 2020 Author Share Posted October 15, 2020 Yeah, some good input. Do you guys spray everything down after each outing? Gunnels / storage - not too bad as I could take stuff out if need be, but I'm worried about the dash, the areas near the isolation switch stuff with wires!

Smobaby Posted October 16, 2020 Share Posted October 16, 2020 Looks like corrosion from saltwater Link to comment Share on other sites More sharing options...
dmck Posted October 17, 2020 Share Posted October 17, 2020 try washing it with a solution of vinegar, then painting it with an etch paint. Painting with a decent paint then also stops the little corrosion points you get from dropping sinkers, hooks, swivels, alfoil etc Link to comment Share on other sites More sharing options...
anthman Posted October 17, 2020 Author Share Posted October 17, 2020 We ended up using 50/50 vinegar and water sprayed, wait a minute, wipe with kitchen sponge/scourer (found the scourer quite abrasvive - it's the dark green one, not metal wool), then wiped over with inox. The paint etch is a good idea, will think of that next time. Link to comment Share on other sites More sharing options...

I better stop using it then.I've been washing the outside only with it and rinsing with fresh water.Boat still looks pretty much new.Cheers.
