Shopsmith Forums

I have been reading about Evaporust here for many years bt never had an opportunity to by any. So recently I was in Lowes getting some stuff and happened to see Evaporust on the shelf so I picked up a quart bottle to try it out. Well I had some Shopsmith brad point bits that came in their original box from one of my several SS purchases. These look like they never had been in a chuck but they were very rusty and being that they came in an original Magna box I knew they were pretty old. So I decided to give the Evaporust a test drive on these bits to see how well it works. Well suffice it to say I was totally amazed at the results. I poured a bunch of the fluid into a small plastic bucket and put the bits in it totally submerged. I left them on the bench and forgot about them. A couple of days later I saw them and remembered I had put them in there so I took them out and low and behold I see what looks to be brand new drill bits. I mean literally they looked brand new.

I am going to chuck them up and drill some holes on a project I am going to do for the SWMBO here soon and I am confident they will drill perfectly as they feel razor sharp after sitting in their box for 50+ years. So if you have some rusty parts that need some restoration don't hesitate to buy some Evaporust to remove the rust as it works like a charm just as everyone else here has stated many times in the past.

I find that it works as advertised although it tends to darken the metal permanently.

I was thinking about trying this out rather than jacking with electrolysis. How do you guys dispose of the waste product? The website says biodegradable and neutral pH so I assume I could pour it in the grass or down a hole in the ground and not feel too guilty?

It is 'reusable', so why 'dispose'? It does get less effective eventually.

I have yet to 'dispose' of any. It will 'disappear' of left open too long.

Mine disappears with the clean up rags etc.

Washing soda is much cheaper. I use evaporust for smaller parts and tubes(pvc pipes), and electrolysis for larger parts.

Yep, EvapoRust for smaller parts. I like to use plastic water bottles. Cut the top off, put the small parts in, then pour in just enough EvapoRust to cover the parts. But it does work amazingly well. As evidenced by this drill chuck I rescued with it:

Wait, EvapoRust can be used for big things too! This car was derusted with a catch basin, a sump pump, and 5 gallons of Evaporust.

Oooooo..., is that an E-Type? What year?

I'm cleaning up a 1951 10ER, a remarkable machine and precursor of the Mark 5. For the most part I could clean the 62 years of use and neglect off the machine with phosphoric acid, brake cleaner, and wood gum solvents. But the saw blade chuck was too rusty and wouldn't come clean. After reading the claims here about Evaporust I hunted down a quart at my local Lowes store. It wasn't even $3! How could something so cheap actually work.

Well, last night I put the chuck, in pieces into an Evaporust bath for the night. This morning I was pretty much astounded. With a little steel wool and a warm water rinse, the parts were like new. A light coat of oil and I was finished. I had my doubts but that stuff is amazing. The pictures here made me wonder but seeing it first hand for myself, made me a believer. I sure am curious about what its made of, though.

Wii evapo rust take paint or chrome off the parts. I have some tools that I want to use them on and I have a few pieces to a Shopsmith that has rust on them

In my experience, which is very limited, Evaporust doesn't hurt paint or what I think are chromed surfaces. Here's what the company says,

[INDENT]Anodizing, Cobalt Tungsten Carbide, Powder Coating, Chrome, Nickel, Paint, and most other coatings will not be removed as long as they do not contain oxides. EVAPO-RUST will not harm lead or solder points.[/INDENT]
