D*mn Barnacles

[riggear]

Recently my Stainless Steel swim ladder unfolded and lay for several weeks in the water. The bottom 2 rungs were covered in barnacle. I scraped them off, but still have circular deposits left.
I also noticed similar ones on my Bronze Prop and the SS Shaft.
i have tried green scrubbie pads & solvents etc. etc.

Any helpful hints how to polish then lil buggers off?

Thanks,

Those circular deposits are actually the glue the barnacle uses to attach to the substrate.

Green Genie works. Spray it on, let it sit thirty minutes, and then rinse. It uses salts rather than acids, so it's better for the environment and for your boat.

It's amazing how fast they grow.

In general I just deal with the little bases left over when it comes to the hull as it doesn't really create fouling and will come off at a later haul out. On the prop and shaft I use a soft steel flathead screwdriver. I'm gentle; it's never scraped the metal that I've seen.

Just make sure not to use anything that actually works... .

Barnacles have feelings too!

Green Genie? This place is a wonder. Have never heard of it but have had the same thing happen with the same residue.

It's my understanding that doctors (plastic surgeons) first got the idea for what we now call "Super Glue" (first used in plastic surgery) from barnacle glue.

In Europe, there's a product called Porgaz. Its a domestic cleaner. I suspect that its diluted HCl. Pour it over the prop and shaft, wait 5 minutes and viola, no barnacles.
