lime-o-sol is ready to spray that's why I went for it. Convenience.

Now for the bad news, don't know about your area, but I can't find it around here anymore.  I had a little left, used it and ordered some on line, that stuff is hard to find.  It works so well, I'm willing to pay the price to have it shipped.

I tried limeAway, but it doesn't work well at all.  I did a test on two sections.  One with LimeAway.  Tried it, worked maybe a little, but 95% was still there.  Even let it sit for awhile, tried multiple times on the same section.  Sprayed a little LimeOSol and it took it right off.  Didn't see any problems with the vinyl sections where I used it.  Wear eye protection, that stuff started burning my hands when I wasn't wearing gloves.  I'd hate to see what it would do to your eyes.

the acids in LimeOSol and LimeAway are different.

I've used Bar Keeper's Friend, which is oxalic acid, with great results on rust stains on the white topsides of boats.

I know - what are rust stains doing on a boat where carbon steel shouldn't be in the first place, but PO's are often cheap or ignorant.  So rust stains it is!

I've learned to use regular powdered citric acid to clean and remove water stains on just about everything.  I picked this up nearly 20 years ago from my department Senior Chief on my submarine.  Dissolve it in nearly boiling water and let it cool to the point you can touch it.

I soak all the shower heads in it twice a year and clean the stains starting to form in the toilets about once a month or so ... and it's literally safe enough to eat and non-abrasive.

Oxalic acid (wood bleach) in hot water works instantly.
Tip.
If you need a lot. When it was selling at stores for about $5. Per pound, I found a pool chemical supplier and a 40# was $55.
Split it with some friends.

Another way to remove rust from vinyl siding is to use commercial cleaning products. There are a few products that are specifically made to combat rust stains. Make sure to choose a rust remover that contains oxalic acid. This chemical targets rust stains caused by iron and water.
