      Rust removal

      I recently found myself dis-assembling a tank car to put it in to service. I had originally purchased it as a static storage tank. The assembly screws were fairly heavily rusted, one to the extend I had to remove it with a small pair of channel locks. Over time watching auto shows I like, I had seen advertisements for a product called 'EVAPO-RUST'. Supposed to be non-toxic, and biodegradable. So I decided to give it a try. The photo below is of two screws from the project. The screw on the left is the screw I had to remove with channel locks. The screw on the right is after spending overnight in the EVAPO-RUST product.

       

       

      I purchased my container at my local Advance Auto Parts store. It is also supposed to be available at AutoZone, O'Rileys, Walmart and other discount stores. I paid about $8.00 for a quart container.

      Hmm, interesting.

      Question, how will chemical residue left on screw affect plastic contacting screw over the long term?

      Okay, it just didn't register. I don't feel good and my brain is kind of hit and miss on noticing things today.

      Bob-

      Thanks for the insight. Any comparisons to LIME-AWAY or something else you have used?

      I'm going to get some. I have found the small brass wire brushes from Harbor Freight (frequently at sale prices - cheap) work well with Blue Magic on rusted parts. However, a chemical reliance makes sense as there is no abrasive.

      I have not used the product, but read their site. Lime-Away is mostly acids, and needs to be neutralized. This stuff is water soluble, so it could be acid, but they also say you can leave it on and get a few months protection, so seems to be a bit different.

      I think if people are concerned, you should be able to get the msds sheets on these products.

       

      update: the joke's on us, the msds for the WD-40 product says ingredients are non-hazardous ... and then they don't list them.

      I've used the EVAPO-RUST for a number of years restoring old furniture, car parts, machine etc.  Works very well.  For items going to still be exposed to air, best to paint or cost with something to seal the item.  I get mine from a discount place called Ollie's that quite often has it for less than $10.00 a gallon.  I've had no problem with screws, bolts and old style nails being re-used in wood, plastic other metals.  For bolts/screws and nails where the head will be visible or air exposed, I spray the head with a light coat and a bit of the shaft with clear acrylic rattle can and then touch up the top once in place and secure.
