Re: Evapo Rust vs Apple Cider Vinegar
Old Henry, it looks as though the only paint that is missing from the right pump is the black paint. The blue paint below it still shows evidence of existing. Perhaps the black paint was never applied correctly to begin with?
Nice article by the way.

Re: Evapo Rust vs Apple Cider Vinegar
I have used evapo-rust mixed with white vinegar and boy does that work nice. rince with water then smear evapo-rust over the part it will protect it from the elements for awhile or until your ready to paint the part.

Re: Evapo Rust vs Apple Cider Vinegar
May be a bit off topic but ever try citric acid powder mixed with water? Mixing 8 ounces of powder per gallon of water I completly submerged a flathead block in a tub filled with the citric and water mixture. After a day it came out looking like new iron even inside the water passeges were cleaned.
Same block running in my rear engine modified roadster at Bonneville holds gas blown flathead record at 192.448. Engine ran cool part of the reason was the insides were free of rust citric acid cleaned it perfectly for a lot less money than using a whole lot of evaporust. |

Yes, time consuming, and I have to clean the anode regularly, otherwise the process stops. After I pressure washers with hot water to get rid of (I say sooty surface has no better word for it). Jorgen |

Re: Evapo Rust vs Apple Cider Vinegar
Saw a product on "Car Fix" tv show Metal Rescue, approx $12 / gal. Works inb8 to 24 hours. Tried it & works great. No scrubbing nessecary. Mostly done in 8 to 10 hours. Here's a guy like us on You-tube demonstrating.

Re: Evapo Rust vs Apple Cider Vinegar
I've used "Metal Rescue" as well (the local "Home Depot" has it in stock), and it seems to be equivalent to "Evaporust" in both formulation and function.

Re: Evapo Rust vs Apple Cider Vinegar
Just keep in mind any acid solution is going to remove good metal along with the bad.

Re: Evapo Rust vs Apple Cider Vinegar
JSeery is absolutely right. The principal used in the chemical reaction is to remove carbon, the carbon is most easily removed in the rust so it reacts on the rust first. But after the rust is gone it will continue to react on the carbon in the steel all be it at a much slower rate. Ya can't just forget about it, gotta keep an eye on it.
