Every couple of years I fill my stand with LPS Hardcoat corrosion protector. Let it sit for about an hour and then drain it back into another container. It can be reused that way. They used it when I worked offshore in Bass Strait (ESSO)it was known as LPS 3 and was extremely effective at stopping corrosion in a very harsh environment. I was at a local Sunday market and a seller had a container of LPS contact cleaner(LPS 1) and a container of LPS Hardcoat (LPS3) in what I believe to be in US 1 gal container, I can't find any size markings on either container. :dunno He apparently had been trying to sell them for weeks with no offers. I got both containers for $20.00 Au :clap: a definite bargain. Made in the US and really good products.
