Has anyone used this new WD-40 product? http://www.wd40specialist.com/products/rust-remover

Interesting!

Cider vinegar is probably just as good and cheaper too.

Also a bath of water and baking soda with a battery charger with a sacrificial cathode will dissolve rust quite well too.

Go to Auto zone and buy a gallon of Evao rust for $20 per gallon. Works great for soaking small parts in.

I have heard of the baking soda-battery charger thing, but I thought that altered the metal some way, perhaps not in a good way?

I believe WD 40 uses silicone and it don't get along with paint. So your asking for trouble.

X2 on the Evapo-Rust. I find it at Orielly's and Harbor Frieght.

[Tempest]

here is a link to the baking soda/battery charger method. (hope it works)

I've used it and have never had any problems with it welded on it after stripping the rust and it welds fine. It's the same system used by the commercial rust stripping services (Redi Strip) and I had the subframe stripped on my 73 T/A in the late 70s with no ill effects. It's just a plating procedure with polarity reversed and plating parts has no ill effects on parts. It is used on tools and machinery to remove rust so I can't see where it would have any effect on the parent metal in any way.

The process is used by archeologists to clean ferrous metals when found in the soil so it is very delicate to the parent metal and will preserve details much better than any acid based cleaning which will remove metal from the rusted object.

Also many videos on YouTube about how to use the process.

Make sure you use washing soda, not baking soda. Also if you use distilled water or RO water you won't get the chemical reaction with the residual chemicals in the water.

[Sirrotica]

If washing soda isn't readily available baking soda can be used, I have used baking soda and it works, from what I have read about it washing soda is preferred and works better read more efficiently than baking soda. They are however interchangeable.

Excerpt from material list:

electrolyte to cause a chemical reaction. This reaction loosens the rust particles from the base metal so you can easily scrub it off and use the tool or car part underneath. The vat in which you will perform the electrolysis should be plastic, preferably a storage tub or bucket, one to five gallon capacity. According to an article by Ted Kinsey at StoveBolt.com, never use a metal bucket or trash can. There may be a danger of electrocution, toxic fumes and undesirable results with your project.

Electrolyte solution is a fancy way to say water with something added to help it conduct electricity better. Most people use washing soda (sodium carbonate) or baking soda (sodium bicarbonate). The difference is simply one carbon atom, and the general consensus at StoveBolt.com and RicksWoodshopCreations.com is that the performance is similar if not identical.

The most readily available electricity source is a 10-volt car battery charger. You will want one with a voltage meter so you can easily see if the current is getting through the rust to the metal underneath.

Finally, you'll need an anode for the rust ions to run to when they leave the tool or part you want cleaned. This can be a steel or iron cookie sheet, pan lid, or other piece of steel or iron that has a larger surface area than the rusty tool.

I am a user of the WD 40 Rust Soak.

Right now, I have a parking brake pedal assembly soaking in it.

Last week, I took all of the innards of a A/C heating box (all unpainted), and soaked them over night.

100% of the rust is gone - looks like new metal.

[PMD1969]

A gallon of that stuff is $35 plus tax . Many years ago I used the baking soda / charger method on an exhaust manifold and it worked well. I did have to use an expendable cooking sheet and a LARGE RubberMaid tub. The OHC manifolds are not small.
