Hi Mike,

First a few questions:

What do the spots look like? How big? What colour?

Do they look crystaline?

Do they look like dried rain spots, but won't wash off like rain spots?

Have they built up over a few outings, or did they appear after just one paddle?

Any chance of you posting a pic?

There should be a fairly easy way to remove them, if I can't work out a solution I'll ask some of the other Chemists in my lab.

Cheers,

Paul.
