Saltaway does work and I think it is worth the money, I have been using it for years and I can not fault it.
I bought my first batch from the US as it was about quater of the price here, you can soak parts in it straight if need be ie; youve drowned you reel or you can dilute as per the instructions and spray on leave it sit for a little while then wash , it leaves a protective film so the more you use it the better it works, would I get it on my line, I try not to, not sure it would hurt but better off not to in my opinion.
