Degreaser Performance Ratings - Independent

Also, consider some of the restrictions. Non hazardous is important to many. #2 and #3 don't recommend use on painted surfaces, which would preclude use on an engine compartment or ag. equipment.

Okay, I'm done.

........really.

I plan on using #2 in my parts washer. On their website it lists "cleaning mowers.." and all kinds of things that have me convinced to test a few spots on painted auto parts.

I hate to go through the fire drill, but at 6.49 a gallon, I can't resist. That, and purple power makes my hands look like I'm 95.

Actually... now that I think about it, I never cut it with any water. Does that make a difference? I'll have to try that next.



Were you using the purple (Even though it's still called Simple Green) solvent or the green all purpose cleaner? I find a big difference between the two. The purple is much stronger. It is a concentrate that you dilute.

Great Info! Very informative. Thank you very much for posting!

I noticed that there are 2 CRC Hydroforce Degreaser's available when I searched online. One is labeled General Purpose and the other Industrial Strength.
I wonder which one scored #1 in the test.

Bamaro- You're looking for CRC Hydroforce Industrial Degreaser PN 14416 (this is the gallon)

They have changed the bottle color and label a couple times, it appears...

I added the CRC full name and part number to the ratings, so should be good to go... thanks for the feedback!

Thank you very much for this.
One question/thought about your corrosion results. Could it be that the water based product possibly leaves a very thin film (oil/grease or the product itself) that protects more against rust?

 

[PiggerAndy]

You bet, Bamaro!

To answer your question:
For the CC-018 Accelerated Corrosion Test, the degreasers are applied to clean, prepped panels... so in that case, actual degreasing efficiency/effectiveness wouldn't change anything. So, no worries that a lousy degreaser would leave behind original, uncleaned grease which would act as a barrier. Just wanted to clarify that.

There are plenty of water-based corrosion inhibitors that could be part of an "additive package" in a degreaser... an example I could give are the types of oxidation/corrosion inhibitors used in antifreeze, for example.

So, in the case of the second panel (the CRC HD), despite being full-strength and solvent/hydrocarbon based, its first sign of rust appeared at the same time as the bare steel control panel... one hour. Personally, that was one of my favorite findings from the research.

Especially in the last 10 years, water-based chemistry has come a long way... the water-based cooling/lubricating/anticorrosive fluids used in CNC mills are pretty amazing, for example.

At work we use Zep ID Red and Simple Green. I like the Simple Green for oil, but it does not help with paint pen or decal residue. Out comes the ID Red. Its petty nasty stuff. Sold as Industrial Use only and cannot be sold in some states unless industrial customer.
I always wear gloves and hold my breath while Im using it.

I wonder how some of these other products work on such problems. I'd probably have to test my self.
