rust remover

[Dale S.]

In the last few days someone showed some pictures of a heater blower fan that had the rust removed. There were 3 pictures. I can not find that post. Would the poster please email me with the name of the product. Thank you Dale

Re: rust remover

I have had good luck with ZEP Rust Remover from the cleaning aisle at Home Depot. Used it on oil pans and exhaust manifolds so far. I let it sit over night.

It disolves all rust and is Phosphoric Acid.

I posted "Steering Column Woes-C2" which has a description. It's currently on page 2. We kinda got off track since thats a subject of it's own.

Re: rust remover

I use Oxisolv from Eastwood. You can usually clean up most rust in less than an hour. Just brush it on and keep it wet. Light rust will be gone in 15 minutes. I acidentally left a thin metal bracket in a can of this stuff for 3 days once and there wasn't much left of it. It works fast and great but don't submerge and forget about it.

It rinses off with water and leaves a zinc phosphate coating to protect the part from rust until you get around to paint or plating. The gallon I have is 18 years old and is still as potent as when first opened.

I was curious also. What is the name of the product?

It's called Evapo-Rust, sold at local Oreilly Auto parts. It's non-caustic and works great. Everyone who needs to remove rust gently owes it to themselves to try some. I'll post a picture of the jug tomorrow.

Thanks Jim. Looks like it works very well.

Most, if not all, consumer-intended, chemical rust removal products on the market are phosphoric acid-based. I've used a product widely available (at least, here on the west coast) called Jasco Metal Etch. It's very effective, primarily because it is a fairly concentrated solution of phosphoric acid.

One of the reasons that phosphoric acid is used is because it's much less "aggressive" than other acids which could be used, so it's more suitable for consumer use. In industrial settings, hydrochloric or sulfuric acid is usually used to strip steel or iron of rust in a process called "pickling". Using these acids, though, calls for much stricter control of immersion times and, usually, an immediate post-pickling dip in an alkaline bath to control rust re-formation .

Phosphoric acid, which is the "active ingredient" in most consumer rust removal products, is an inorganic acid. Therefore, one could expect it to have a VERY long shelf-life; practically "immortal".

Re: rust remover

Here are the two products I have used. Both perform about equally. Safest-Rust Remover.Com has a website that describes their product; which has to be ordered direct. Variables that affect the performance include: Temperature-works faster in warmer weather, Strength-fresh batch works faster than used, Degree of rust-obviously speaks for itself, Agitation-moving the part around ocationally and wiping off or brushing with toothbrush or similar speeds up process. Use the smallest container the part will fit in to conserve (it ain't cheep). Good luck all.

Re: rust remover

I have been using the Safest-Rust, S-R, for the past 3 years. Best part is that it's non-acid base! Yes it can get expensive, so I remove most rust by other methods and finish with the S-R. For bolts and electrical parts its the only way to go. If left in to long the part can develop a blacken tone which can be washed off (ware gloves to keep black off your hands).

Are you sure it's not acid-based? The blackening you describe is very characteristic of phosphoric acid. Plus, it's hard for me to imagine anything other than an acid-based product being effective in dissolving rust. Did you ever or can you measure the pH of the stuff?

Joe,

Check out the info at the link below. I think you will be impressed. I purchased a gallon last year and I love it. The company claims "no acid of any kind", and I believe it.
I never use anything with even mild phos acid for removing rust.

Most likely, the Rid-Rust is close to the same stuff as the other product mentioned above.

Re: rust remover

The best product I have ever used for this is "Rust Clean" by Amazing One from Howell, MI. The manufacturer claims it is a "...water based biodegradable, non toxic product..." "The solution has no acids, solvents, or VOC's. It is nonflammable and non corrosive. No fumes or odors are produced and Rust Clean is safe on hands and skin." It leaves a clean, like new surface on even the rustiest steel. I just drop small parts into it and leave it overnight for truly excellent results. It cost about $30 a gallon the last time I bught it at a swap meet and it lasts a very long time.
