Any recommended way of smartening up a scatched sink?

Any recommended way of smartening up a scatched sink?


We rented a place with a naff SS sink when first married. I cleaned it with
fine wire wool and chrome polish, followed by Brillo Pads and washing up
liquid. This gave a fairly even Matt finish which was clean and stain free.
It took a couple of hours but looked pretty good.

I suspect any deep scratches may need some wet and dry paper.

The washing up liquid acts as a lubrication and reduces the €˜cut of the
wire wool or wet and dry.

Rubber abrasive block, like an eraser but with an harsher abrasive embedded.
Polibloc or a similar name... Rub in one direction, to produce parallel
scratches.

Fair bit of work, but easy to stop and resume.

I just knew somebody would say that. Also stainless seems often to be a bit
of misnomer. Ours may or may not be stainless but I can attach a fridge
magnet to it,yet others I can't so its some kind of alloy. and it seems to
be stained by tea.

What type of wheel do you suggest?

While the reply may have been meant tongue-in-cheek, there *are* some discs:
"Flap Felt Disc Metal Polishing Angle Grinder Buffing Wheel Polishers" will
work, using a suitable buffing compound. Or "Nylon Fiber Polishing Wheel Sanding
Buffing Disc Abrasive Wheels for Angle Grinders", as a first go if it's badly
scuffed.

(both found on leftpondian Amazon, .co.uk availability left as an exercise for
the reader...)

Beware that buffing wheels pretend to be benign and harmless, but can snatch
violently. A firm hand and cautious eye, and the sink will be buffed to a mirror
finish (and then will show every tiniest spot of limescale, YHBW.)

Stainless steel is an alloy, also some stainless grades are non magnetic
as used on submarines.

I like the sound of that rubber abrasive block - as a tool for occassional
use.

I'd expect a coarser block (120 grit, maybe?) to do a sink in under an hour,
depending on how picky you are about getting it even in all the corners and
bits...

Stainless _is_ a misnomer. The French call it inoxydable which as you
may guess means won't oxidise or rustless. Which is closer, but not
entirely true.

Not really a misnomer - it stains less than mild steel. Leave a
Brillo pad on it, however, and you will soon see rust marks.

Some SS is magnetic, some is not.

Once you get it to a decent state, a foamed melamine "eraser" block can help keep it looking good.

In short we call it inox.
I once came across a big SS screw that was magnetic at one side but not
at the other.

Well I've learned something today - that there is a non-magnetic allotrope
of iron. I'd naively thought that anything made of or containing metallic
iron was ferromagnetic.

Did anyone ask how deep the scratches are ?

This is a stainless steel sink factory and
their robotic sink finishing section. There's
no closeup of the Brillo pads the robots are using :-)
This section seems to be finishing the bottom of
the sink, rather than the whole thing.

Ferritic stainless steels are still magnetic and easier to work with.

Austenitic stainless isn't too bad at resisting most things.
It should also be non-magnetic if of suitably high quality.

Both forms tend to have very sharp edges if you make a mistake.
