So after switching to Fireclean for most of my firearms needs, I still had some extra bottles of Hoppe's Elite and Mpro-7 lubricants laying around. Got bored and I wanted to test Fireclean head to head against the previous brands I was using. I've also seen the attention that Froglube and Fireclean has gotten on social media, and also added that in to the comparison.
The test subjects:


This test compares the corrosion resistance between these different brands on stripper clips, which consist of steel and brass.
Day 0:

Equal amounts of coating was applied to each stripper clip corresponding to the brand name minus the control which has no lubricant applied to it
This was placed on my deck where it was exposed to natural humidity (I live next to a large lake) and direct summer sunlight

Some notes:

Fireclean and Hoppe's Elite were both clear and odorless

Froglube has a green color and is a lot more viscous compared to the other brands tested here. It also has a minty toothpaste like smell.

Mpro-7 has a yellowish color to it and a slight odor

After 3 days, there was no significant change to these stripper clips. I decided to add equal amounts of salt water to each stripper clip to accelerate the effects of corrosion.
Day 4:

Rust starts to form on the control clip and corrosion starts occurring on the brass

Fireclean, Froglube, and a little bit of the MPro-7 starting to bead up

Day 5:

I experience strong summer storms like this happening occasionally for the rest of the week.

Those beads have dissapeared. All of the clips felt dry to the touch except froglube which remained greasy.

I go on vacation and leave the clips on the deck for the remainder of the time.
I return on Day 14 looking like this:

Slight corrosion on the Fireclean and Hoppe's Elite. Mpro-7 and Froglube seems to suffer the least amount of corrosion. All of the other clips felt dry to the touch except for Froglube, which you can visibly see still have a light coat to it, even through all the rain its been through.

Thanks for taking the time to read this
Of course this is in no way a comprehensive test nor should it be treated as such, but when I get some more access to metal pieces I might do one.
I might do a coefficient of static friction test if it sparks enough interest.

I approve of this science

Thanks for taking the time to post... I love the Lube Tests!  
They're always different!




.

Awesome post.  Thanks for the information!

Nice post OP and thanks for including FrogLube CLP.  I just recently made the change to it and haven't looked back.

OP- a stripper clip is steel and brass.....not aluminum and brass.  

Nice work.  Thanks for posting.

Thanks for clarifying. There's not much information out there about material type.

I really wanted to see how froglube and fireclean did head to head as they both are getting popular on social media and a lot of people i know swear by one of those 2.

Thanks for post OP.

3 week update:

Fireclean starting to take on a bit of rust. M-Pro7 starting to develop rust on the edges, but not so much as the Hoppes and Fireclean. Froglube is still slightly "greasy" and developing tiny spots of rust, but i'm willing to say it's the clear winner in this particular test.

FWIW I took a stripper clip, cut it in two and applied Froglube CLP to both after heating them up.  I used the paste on one and the liquid on the other and left them both set outside of my house on a small table.  After about 6 weeks of no rust having set through rain, humidity and heat of good old South Carolina I decided to just throw them both away.  I have found that this product just works.  FYI I have no connection to this company I just use some of their kit and by no means was my own test scientific or an end all be all to any others.

In the last pic, the brass on the Frog Lube has corroded as much as FireClean.
