Rust stains on fiberglass

[Mike and Joanne Stimmler]

Anyone know of a easy way to renove rust stains from fiberglass? I think one of my helpers used a steel wool pad for cleaning something in the cockpit last week and this weekend I have little rust freckles all over the place. I have reduced some of the stains with Simple green but not eliminated.
I've heard that oxalic acid works but am hoping for a simpler solution. Any ideas?
Thanks,
Mike

FSR, fiberglass stain remover, made by both Davis and West Marine.  It's a blue gel.  We also use it to remvoe the bow "moustache" before rewaxing the forward section of the hull.

Lemon juice might work.  I use it to disolve the mustache.  Bought a pint, put a spray head on it, works great!

The best I've found is CLR which you get at any home depot or hardware store. (Remember the old info-mercials.)  FSR works too but is 3x the price.

Ken - After you use it to dissolve the ICW mustache do you have to rewax?

Joe

[Stu Jackson]

Yes.  Or, wait'll it grows back and redo it over again!

Mike : Stu's correct on the FSR as it has oxalic acid in it. 
You can also get a dry powered cleanser called "Bar Keepers Friend" in the grocery store.  It also has oxalic acid and really works great.  I've found it to be better on deck stains than FSR.

Thanks Everyone, I'll give them a try.

One more input for cleaning off Rust Stains. There was a good article in Practical Sailor In the May 06 issue page 30. It concludes with the recommendation of Star Brite rust/stain remover and also recommends FSR.
Good luck, dave

2nd Bar Keepers Friend.
It's cheap, easy, and easy to get.

Spelled Whink. We use it in the boat yard all the time, NOTHING works better.
Usually get it at Ace hardware.

We decided to try the FSR since it is a gell thinking the powder cleanser type cleaners would be abraisive. The gell worked so well that we did the whole deck with it and it now sparkles and it did a great job on the rust. BTW my helper who used the steel wool should be out of the hospital any day now 
Thanks,
