I have a particular machine where soluble oil/metalworking fluid has
dried out in the sump. How do I remove the dried out stuff to prevent
clogging of the fluid system with the remnants of the old dried out
stuff.

The substance is called hangsterfer S500.

Thanks

Hot TSP solution will not only soften and remove the old stuff, but also
clean the metal of the tank.

Make up a strong solution -- say a cup TSP per gallon, and heat it up to
near-boiling, either in a separate pot or in the tank with an immersion
heater. Let it work for as long as you can stand. A couple of days of
soaking will get it all pretty much limbered up and removable.

PS... it's not only dried, but oxidized to a varnish. Varnish is not
water-soluble. But strong, hot TSP solution is ALSO a "varnish remover"

Spray on oven cleaner removes it in seconds.

Just be sure you get real TSP. With the rampant greenies out there,
there are a lot of fake TSPs on shelves now. Like the "green" mineral
spirits, which don't work worth a hoot.

However, that won't get it out of nooks and crannies you can't reach with
the spray. It's great for open surfaces, though, and won't hurt
steel/iron. Eats hell out of Al, but then, so does TSP.

Yes. Sellers of real TSP spell the chemical name out on the box, so
there can be no confusion.

The standard brand is Savogran and is available at real paint stores.
Hardware stores often have only "TSP", which is usually sodium
silicate, which will not work.

If it really has oxidized/polymerized, TSP would be my distant 2nd
choice. Lye would be much better; 1 lb/g or stronger.

Lye is much harder to find. It used to found in hardware stores, e.g.,
Red Devil brand, for cleaning drains. But it was being used in drug
mfg, IIRC, and isn't carried anymore. I get mine online, from a
soap-making supplies place.

Don't leave more than a couple minutes unless the paint is epoxy base.

Oh, and another thing that melts away grime amazingly well is to spray it

I bought a can of Drano Crystals at Lowe's recently. It was the only
place I could find it around here.

If you're going to use it for something other than drain cleaning, do a
test first. I once tried to use Drano as a paint remover, cause I had
used lye to do it and I thought Drano was just lye. It was a disaster -
there was some other ingredient in the Drano that contaminated the work.

Here's where I get lye:

This does work well, but do it outside, even if the weather is
unpleasant.

Ether fumes are extremely flammable, and if used in a basement, may
find their way to the pilot of the gas-fired hot water heater and
explode. Or be set off by the spark in a light switch or a control
relay.

I've used TSP on aluminum, without problems. Lye, and washing soda
(OxyClean and such) are the aluminum (and aluminum/zinc alloy) molesters.

Dilute lye can be used on it, too (for a time). Hot, concentrated TSP is
quite corrosive to aluminum; enough so that it's sometimes used as a
prep etch alone or in combination with other etchants, because it also
acts as a surfactant to wash the item clean after etching.

All sorts of things, actually, can vigorously attack aluminum because of
where it is on the electromotive series. Lest you think I'm crazy, let
me warn you that this is not obvious -- but water with a pH just barely
basic of neutral attacks aluminum VIGOROUSLY under certain circumstances;
so vigorously that it can cause substances to heat to the point of
ignition.

All of us pyrotechnics guys are aware of the dangers of water and
aluminum. There have been numerous fires, many burns, and a few deaths
because of it.

What's the best cleaner for baked-on crap on a toaster oven aluminum
pan? The perimeter of...er, someone's, is just black with it.

Oven cleaner contains lye and is contraindicated.

what hot water can jar loose, given time.

Sounds like a plan. I'll toss it on the BBQ, full of water, after my

Many commercial dishwashing detergents are rated for "boiling out" a
deep fryer. Given the wide use of aluminum in food service equipment,
I bet there are detergents suited for use in boiling out an aluminum
utensil.

Here's one:

The key is "metal safe".
