How to get Barnacles off a PVC inflatable?

[Scooter]

Anybody have any ideas how to get barnacles off of a PVC inflatable?

That is without (of course) damaging it.

My friend has an inflatable that I might get (almost free) which is covered with small "remnants" of barnacles. It's very tedious manually scraping them off with a delicate touch.

Anybody out there go through this pain? Chemicals/solvents that won't hurt the PVC??

So far I've just tried soaking them in water and it's a little easier but still time consuming. The price to pay for a cheap (and otherwise very good) dinghy. It's about a year old but it sat in the water just long enough to get them started. They are all small but many, many, of them covering the bottom.

Scooter : Try a household leaner called "Lime-a-way".  It might dissolve the ruminates and should not hurt the PVC.
You'll have to use multiple applications of Lime A Way!!
