Testing WD-40 against water patches. Which is cleaner?

@BP Addict - Walt, as stated that's somewhat misleading, so if you don't mind me adding a clarification.

The conclusion was from a test of 56 or more preservation solvents/solutions and it was not the basic WD-40 that out-performed them all, but it was their special and expen$ive ($15 for a 6.5-ounce can) "WD-40 Specialist Corrosion Inhibitor" that was tested in long-term salt exposure sprays to be THE BEST of the best, along with a special RIG grease-based product, but the spray is easier to use, of course!

I use that WD-40 SCI on SS hardware and mechanisms on boats, as I maintain a fleet of boats used 24/7 in salt waters, and I can attest that it is THE best I've ever used for a spray or liquid product.

If I need a protectant/preservative grease, I'll use the blue-colored synthetic grease made/sold by or as OMC/Bombardier "Triple Guard" marine grease. That still protects even when compromised 30% with saltwater. In fact, I apply it to my MZL'dr barrels before pinning them in the barrel channel; it is quite thick, needs to be rubbed out to apply a thin coat, but it stays in place and it doesn't run. It's only $12 for a HUGE tub that lasts me many, many years, and I'll take care of over a dozen boats and motors in those years, plus 3 of my own. (Note this product wasn't tested in the large field test noted above.)

Note: Like others ... I just clean with good ol' water!

I had a hunting buddy use wd-40 to clean his shotgun. One cold morning goose hunting, a flock came over and he pulled the trigger. Heard a faint "click" and nothing. Firing pin was so gummed up it wouldn't strike the primer hard enough to fire! I stay away from it on firearms.

Many years ago my basement flooded and in an effort to save all I could I grabbed a can of WD and sprayed my guns. Sometime later I went to clean them up and they all had a thick, sticky residue all over them. At the time I didn't know there was more than one kind of WD so I can't say what it was. Probably just what I grabbed at Walmart.

WMD-40 when it is made for walmart for some reason to make it cheaper they add molasses to the formula

Hopefully you said that in jest ... as it doesn't align to the Safety Data Sheets (SDSs) that are mandated by Federal Law for any version of the solvent.
