Thread: New Acquisition

Hi Nathan,

I hate rust with a passion and I'm always on the lookout for products to vanquish the beast. I happened upon this stuff purely by accident and I bought a 1 liter bottle to try it out.

The results were mind boggling. It literally eats rust away like sandblasting would and it doesn't do anything to paint work as long as there is no rust under the paint. It pretty expensive at about $22/liter but it dilutes 1 to 5 so you end up with six liter of solution per liter product. You just soak it 24 to 48 hours and the jet wash brings it back to new looking steel.

Its Australian made, water based and apparently completely safe for the environment. It's a mild acid of sorts (see MSDS) and just about every steel part on my car is back to shiny metal before it gets primed.

how do they get away with a MSDS like that?
says it's acidic, but no mention of which acid?


looking at your picture of the brake backing plate and stub axle, did you separate those two parts when dunking in the acid?
the reason for my question is that if not separated there may still be acid working away between the parts.


there is also another insidious acid problem called hydrogen embrittlement, it causes things to fail.

Hi Harry,

The parts were all separated and washed in clean water using my Karcher jet wash.

The ph is higher than that of cleaning vinegar, so I'm happy that there would be no adverse effects. I've had an old bolt in a sealed container with the stuff in concentrated form for more than 4 weeks for just that reason, and it does nothing more than clean the rust off. I'm not advocating the product in any way, just reporting on outcomes.

I'm personally loving the results and all the parts have been cleaned, primed and top coated ready for rebuild.

The first of my three deliveries of wear and replacement part have arrived and I'm planning to spend the long weekend working towards having both axles ready to go back under the chassis.

Cheers,

Lou
