Barnacle Removal.

[Windcree]

This past season I launched a new inflatable. But.. made a stupid mistake by not painting the bottom. WOW those barnacles are BIG... Well I scraped off the tops but the bottoms are of course still stuck to the bottom of the raft. I've heard of using citric acid to get them off. Has anyone done this? Any suggestions??
..... Oh come on... I can't be the only one to make this mistake....

Thanks

No you are not the only one..... unless you do it twice.
I would us On-'n-Off. Either the regular or the gel formula. I think the regular works a bit better, but both will dissolve the barnacle rings. A non-scratch 3M blue scrubby pad will help too.

Vinegar helps also

I have a big jug of Lime-away I got at home depot. I don't paint bottom either but brush the bottom once a month.

Vinegar dissolves the bases

Calcium carbonate (a.k.a barnacles shells) are a base
