cillit bang corroded (?) my sink?

Correct me if I'm wrong, but shouldn't that be the other way round? If the magnet sticks that would suggest the sink was in fact stainless steel?

I got confused with normal steel. D'oh!

Try Astonish Oven Cleaner - the TV advert states that its non corrosive

A word of warning - one thing that does attack stainless steel is chlorine, just like you will find in bleach. I would be very reluctant to use bleach on any stainless steel. (Same reason you should stir salt as soon as you put it in a stainless steel saucepan, as salt contains chlorine.)

My favourite method for cleaning stainless steel is to heat up some vinegar in a pan until it just starts steaming. At this point it starts to irritate the eyes/nose if you get a whiff of it. I then wipe this over the bowl/pan and the steel comes up lovely. It actually etches the surface coating slightly, so not something to do every day, but does tend to clean it really well and the surface coating will reappear very quickly.

Or you could try stainless steel wire wool. DO NOT use mild steel wire wool like you find in Brillo pads. The non-stainless steel will start the stainless steel rusting.

And in respect of the magnetic properties of stainless steels, there are two common types of stainless steel - austenitic and martensitic (named after the chrystal formation of the metal). The austenitic is ductile but will not hold an edge if sharpenned, so it is used for sinks (which are pressed), spoons, forks and many common items. Martensitic stainless steels are hard and brittle, but will hold an edge so are used for knives.

Austenitic stainless steels (sinks etc) are not attracted to a magnet. Martensitic stainless steels (knives) are attracted to a magnet.

Had similar experience with Cillit Bang too!! It made bin lid and breadbin lid look all rusty. I just used a scourer and it came off after a good scrub!!
Looks good as new now...

I too will never use the damn cillit bang again :rolleyes:
