Removing Shell like Growth?

If I remove the worst of this with a plastic ice scraper what will remove the rest?

I've got some octalic acid but I also hear muriatic acid is good?

Hull cleaners are about 20 a pop plus P&P

Sorry if I'm being thrifty but I don't want to mail order something if I can get it locally

Anything acidic will get it off. You may find muriatic acid (hydrochloric acid) sold as Brick Acid? or if you can find a low cost descaler it will probably be phosphoric acid based. Oxalic acid will work but might not be that quick/might need a lot.

Whatever you use, think about protecting your skin, clothes and eyes, and how you will get rid of the waste - and make sure you thoroughly rinse it all off.

Would any of the household limescale removers work? I was thinking of the stuff you see advertised on TV???

Probably not strong enough, but if you have some at home, It could be worth spraying/brushing some on, or mixing it with walpaper paste to make something to paint on and leave for a while.

Probably will not work, but might be worth a punt before going down the hydrochloric acid route?

I've used Cillit Bang Limescale & Shine for small areas of worm casing on tubes and around engine mounts. You have to leave it on for quite a while and then rub off with a scotchpad. It works well though. It has phosphoric acid in it.

Either way, I'd recommend keeping the acid dilutions weak and allow them to work over an extended period of time.

When your veins are made of hypalon you need a Searider in your life and maybe some brick acid too

Thanks for all your help with this
