My son's Sinkmaster 750 disposal was stuck and he asked me to look at
it. It definitely was frozen but loosened up after using a crow bar and
a water pipe. I feel that it had rusted because of non use. It is only 4
years old but is only used on weekends. Is there something he can add to
keep it from rusting? Will silicone oil or vegetable oil work? It was a
real struggle to free it up.
For what it's worth, I've always had Insinkerator brand disposers (we
even had one in the house i grew up in), and over all those years I've
never ever seen one rust stuck. They're well under $90.
I don't have one now, and don't miss it, though.
Replace or remove are two options to consider.
I'm not sure you want to be dumping much in the way of oil down the
drain, but I can't imagine a little vegi oil would hurt much and may

IIRC 80% of sink disposals in the US are made by Insinkerator, under
several or quite a few brand names, including house names.
If it has a hex hole in the bottom center, it is probably
Insinkerator. Off brands are maybe 5% cheaper but might have a year's
shorter warranty (2 instead of 3. Don't recall the high end
OTOH, with my 1 step from the bottom disposal, I couldn't really get
any pry-bars in, so maybe yours is made by someone else.
The wrench that fits the hex hole in the bottom is very convenient,
but not very long. But I could turn it pretty hard. The problem was
that the disposal itself started turning and I was afraid I would
break the outlet pipe or the drain. And the torque was limited by the
fact that the whole thing started turning.
Both of mine have rusted shut. But I don't use them for grinding up
waste I *put* in the sink, only for things that accidentally fall in
the drain. Once every month or two. They still lasted about 10 years
each. No wear. Just rust. :) With this new one, I plan to run it I
guess once a week. No need to use water if one is running it only for
I lost a washing machine once because I didn't use it often enough.
The main bearing inside the agitator rusted shut.
When my first one froze up, I tried to take it apart. Other than
obvious trim, the top of the intake chamber, I don't think I got a
single part off.
I think mine is stainless. It's an insinkerator.
I took it apart when I replaced the sink, it wasn't corroded... but it
was grimey and kinda stinky.
I use mine once a week on average as well, I have no trouble and don't
ever have to lube it. Not saying that you have an inferior unit, just
an inferior impeller thing...maybe you could just replace the impeller
piece rather than the whole unit.
Again, not sure if mine is stainless... it just wasn't rusted. They
may all very well be carbon steel.
My garbage disposal was stuck last summer. I got it free with a pry bar.
It worked for a couple of seconds, then seized again. This was after work,
second shift. I took it off from under the sink. I found a nickel wedged
between the rotor and the housing. It's clearance is less than a nickel's
thickness. It took me about 10 minute's to pry it out. My wife come's home
as I'm reinstalling it and want's to know what's wrong? I tell her the
disposal was jammed with a nickel. Then she tell's me she had ants in her
purse and she cleaned it in the sink. I now have a disposal strainer.

Ours quit working effectively awhile back. Took it
out and disassembled it and found that little balls
of solder had gotten into it. The balls are small
and soft enough to get under the "beaters" (or
whatever the swinging things are called) and cause
them to not move. Removing all the solder proved
to be nearly impossible so a new disposal was
installed and a new house rule about not letting
the soldering iron droppings get into it was
