The lid of my top-loader washing machine shows rust in a small area (the
edge of the inside rim). If allowed to continue, this rusts will stain our
The machine is about 10 years old and works great. Would hate to buy a new
machine to compensate for this little defect.
Is there anything I can do to chemically eliminate the rust and then paint
over it with appliance enamel? I tried to get down to bare metal but it's
difficult, if not impossible, to get to get a wire brush or other implement
into this area.
You're joking - right?
You'd actually consider buying a new machine because of that *blemish* ?
There is no way that any rust residue (and I doubt there is any) would
actually get into the tub to the extent that it would stain anything.
But if you must attack this "major problem", try sandpaper or steel wool
A chemical remedy is too messy given the geometry and orientation of
that blemish, unless you take the lid off.
Or unless you soak a paper towel with muriatic acid (diluted 50:50) and
let it sit there for an hour. But good luck finding a pint (instead of
a gallon) of the stuff at Home Despot - or anywhere else.
Any acid, preferably one made for the purpose. CLR will work, so will any
of many available at auto parts stores that carry paint. They work by
chemically reducing ferric oxide (red rust) to ferrous oxide (black rust).
Paint afterwards. Rust-o-leum makes paints - rattle cans - speciffically
designed to go over rust.
You could just use a rust converter, like permatex sold at auto stores, but
will look ugly, but will not stain. Or you can sand it, and spray paint
after masking with appliance epoxy paint. You can paint over rust converter
but will bulge a little.
someone mentioned Naval Jelly- and that Loctite bought them. Loctite
also apparently bought 'Extend"- Naval Jelly removes the rust--
Extend *converts* it.
I would choose Extend for this one-- it turns the rust into an epoxy-
*Follow* the directions.
I've tried rust converters, with poor results. You can remove the loose
rust, or or just sand it. Rig a little piece of wood or even a
toothbrush, wrap with sandpaper and get as much rust as possible. Clean
with denatured alcohol and paint right away with rusty metal primer and
Rustoleum enamel. Make sure moisture doesn't collect there after using
the washer, and give paint time to cure before exposing to water.
I have used at least 4 rust converters. One was from a spray can, and I
don't think it was water based. Didn't seem to do anything. A couple turned
purple, seemed to work well. A popular on my datsun forum is Por 15 .
I have used navel jelly to form a rust converter, but it takes days,
months. By applying to auto, it eventually formed a very hard coating. I
already mentioned permatex in a bottle.
