OT On/Topic... removing rust the easy way.

[woodchucker]

I watch some u tube videos. Mr Pete (metal working) had a nice tip on
using vinegar rather than electrolysis.

Well, it worked great. I picked up a miter cutting blade for $5 the
other day. It's a big cast iron piece and I'll show pics when complete.
It was all rusty and grimmy. The vinegar removed the rust really well
and quickly.

I tried the same on a cast iron machinists table I got recently. it had
a coat of rust and would not work for welding (ground). put some paper
towels on and poured the vinegar on, the rust came off and now my ohm
meter shows excellent conduction. Before the meter would not move, and
sanding the rust was not working... so I'm really happy about this.
Cheap, stinks, easily neutraulized with water, just oil after.

You do have to clean the parts first, the vinegar won't cut through oil
and grease.

Good to know! I have also found, by accident, hat most any Titebond
type PVA wood glue will remove rust also.

Keep a gallon of white vinegar on hand all the time. One of the most
useful chemical compounds known to man.

I just used it last week to do my every 6 month drain maintenance on all
the drains in the house (with baking soda); to clean out the Kuerig
coffee maker, and freshen up the dishwasher; to kill some weeds growing
up through the decomposed granite (in lieu of RoundUp).

And, added a tablespoon in with two cups of raw rice cooked in the rice
cooker ... keeps the rice from getting gummy.

After my AC guy told me to use vinegar instead of bleach, cheaper, in
the AC drain I also started using it in my sinks.
Soak you faucet aerator in vinegar and it works like new again.

main ingredient is water in vinegar

water removes rust well too once oils and grease are removed

maybe the acids in vinegar increases the reaction time or it may
make the water penetrate better

might be improved ion exchange over just plain water

hmmmm

Vinegar is also a chemical used is photo developing. But probably not

Speak for yourself :-)

[Scott Lurndal]

Acetic acid has a number of uses, including as precursor to PVA (which
is why PVA glues have a vinegar odor) and a component in Acetylsalicyclic acid
(ASA), AKA Aspirin.

Vinegar is very dilute Acetic acid.

[Swingman]

I'll cheerfully provide the gumbo just to watch that. lol

Now, if you eat boiled crawfish with chopsticks, we could take that on
the road...

Yeah. It's often referred to as "sticky" rice. A distinct species of
rice which is very "glutinous" (gummy) and is supposed to cook up like
that. If you don't like yer rice, "gummy", then choose a different
type of rice. Long white rice and basmati are "fluffy" rices. ;)

Look at you .. telling a coonass, who can look at any rice field and

I was a photographer for 50 years. Neither I nor anyone I ever met or heard
of used vinegar in photography. Acetic acid, yes; vinegar, no. The acid is
often used to stop the action of the developer which is basic.

Glacial acetic acid is generally 28% acid. I never measured but probably
used about 1 ounce per 32 ounces of water which would be around 1% or less.

He probably meant "vinegar" in a generic sense, rather than household vinegar, per se.

Most medical "film" processing is all digital, today..... X-rays, CTs, MRIs, etc. .... Probably similarly with regular photography. Digital makes images more clear and sharp, as opposed to old style X-ray, etal, imaging and processing. Zeroing in on the mass of a patient or area to be imaged, via computerized "measuring", is much more efficient and exacting, than a tech's manual measuring & positioning, etc. Digital facilitates a real helpful advantage, since one can send images across the world in an instant, vs hand carrying sheets of negatives from office to office.

Soon after we retired, our "old style" (sheet film) liquid Developer & Fixer (vinegar) X-ray processing became obsolete. I'm not sure if film companies even make available the hardcopy film, for those obsolete processors/processing, anymore.

OK, speaking of rust, vinegar and coffee makers:

I picked up a cowboy percolator at a garage sale last weekend. There
was coffee stains in the pot so I used the trick I use for my stainless
steel carafe: put some hot water and powered dish washing soap in the
pot and let it soak.

This worked great for the coffee stains but revealed some rust on the bottom
(inside) of the pot. I have not done anything with the rust yet but here's
my concern:

I wonder if the enamel coating has worn off of the bottom of the pot exposing
the metal. Am I going to have an on-going rust problem, so much so that I might as well just toss the pot? The thought of making coffee in a rusty pot takes
away from the allure of using a cowboy percolator on a propane stove - err, I
mean a *campfire*. Yeah, campfire, that's what I meant. ;-)

Any thoughts on permanently removing the rust/sealing the surface in a
food-safe manner?

Last crawfish boil around here was 1993 at the Shoreline Amphitheatre
"New Orleans by the Bay"
(with the Jerry Garcia band, Neville Brothers, B.B. King, Dr. John and Little Feat).

With practice, chopsticks are as useful as fingers for holding the
little buggers, but for most, fingers are quicker.

I usta eat shrimp shells, specially the tails.

I agree, crawfish shells are inedible. I suspect shrimp shells usta be
similarly thick, but shrimp farming has rendered shrimp practially
shell-less. Remember when Thai shrimp usta be called "black tiger
prawns" or jes "tiger prawns"? Now they should be called "ghost
shrimp" cuz they're all white and bleached out. I won't even eat
shrimp, anymore. 8|

Camping and worrying about a little rust don't seem to jibe, either... :)

Shoulda' not removed the protective layer, it'd kept it all covered!

I'm sure none of the high-temp enamel-repair paints are technically
covered for food contact, but I'd think it highly unlikely would be any
real issue once were fully cured and baked out a time or two.

OTOH, I really doubt there's a serious issue anyway for such occasional
use unless it had a lead-soldered seam or somesuch (and even there I'd
not expect the exposure to be significant owing simply to it not being
an every day occurrence).

But this is coffee I'm talking about. Sacred Nectar Of The Gods.

I've got a mason jar of cold brewed coffee concentrate in the fridge as
we speak. Cold brewed concentrate is the only thing to use for Iced Coffee.
Even the ice cubes are made from the concentrate.

It was somebody else's protective layer. I need to build up my own.

That's a thought. Don't tell SWMBO.

I wonder where I can get the matching blue with the white specks. Does
Benjamin Moore sell Cowboy Coffee Pot Blue?

Of course, I'd have to baked it in the portable camp oven.

If you see rust spots through the bottom I'd watch out. The porcelain,
I know you said enamel, will break away is small pieces with the
chance of cutting up your insides good. If it really is enamel, then I
don't know.

[Markem]

I have an old gray and white speckled coffee pot comes with the rest
of the set, not going camping any more.

[DerbyDad03]

Is that an offer? If so, what are the details of the deal?

[DerbyDad03]

It's similar to this, which I've always known to be enamel:

http://www.ebay.com/itm/like/381510776534?lpid=82&chn=ps&ul_noapp=true

No, the rust isn't through the bottom. After further inspection this evening
it appears that the base of the grounds basket has worn away the enamel on
the inside bottom of the pot in some spots from use over the years.

It's called "vitrified enamel" The enamel is baked to a "glass"

I'm going to add that the slotted screws that I could not break loose
even after spraying with blaster, came loose with a long soak in the
vinegar.

So that's really great also..

So go fix an old tool and enjoy it.

_Waiting for Columbus_ is still one of the best live albums, ever.

(Although, _Made in Japan_, _Strangers in the Night_ (UFO, not Sinatra),
the _GRP All Star Big Band 10th Anniversary_ and _Road Scholars_
are excellent as well). Just recently, amazon recommended _Black Symphony_
and it has grown on me over several listening sessions).

vinegar also works well on plumbing fixtures with hardwater deposits

Sorry, I meant if the rust is through the porcelain/enamelware. You
would know because there would definitely be an edge where you can
catch your fingernail on it, or your skin would feel the edge.

Had a pan that did that, and OUCH, I felt it in my mouth a piece or
two, very tiny. In my case I tossed the pan lest anyone at home would
use it.

So if you use it, keep a watchful eye for future deterioration.

And Clare was right on the money.

No "lip', just a few rough, rust colored spots right where the steel
basket sits.

I found some some food-safe enamel paint, but it's temperature range
only goes to 200°.

http://www.piwine.com/gondola-enamel-black-500cc.html

Specs emailed from their customer service department:

-20° F if surface is not flexible and up to 200° F.

Even though the ideal water temp for coffee is between 195° and 200°,
that is very hard to control in a percolator. Theoretically, only the
water under the basket base should reach the boiling point but of course,
that's right where the paint would be. (not to mention the flame under
the pot) Food safe or not, I don't want melted paint in my coffee.

You might want to google "torch enameling". The existing coating is
melted-on glass and apparently you can melt on more glass with a propane
torch. Whether it will bond to the metal and the existing glass I have
no idea but the stuff to do it is cheap and if there's no local supplier
you can get it on Amazon. I'd make sure I got all the rust off down to
bare metal first.
