My kitchen cupboard handles have all developed this flaky peeling sort of texture slowly over the past year or so. It was worse previously, some had a brownish sort of tinge. The letting agent mentioned it at my last inspection, and offhand I just said that I know - it's weird, tried to remove it on one with some kitchen spray and the rougher side of a sponge (e.g. the colouring) but didn't help much.
I got a shitty letter a week after with my renewed tenancy agreement saying I had admitted to causing the damage with a scouring pad and this would need to be addressed. 
There are about 10 handles, obviously I haven't scrubbed them all to oblivion with a scouring pad and caused it. Who would do that?  I just said I tried it once on one handle AFTER it had happened.
Irrationally annoyed me so much. From google I think it could be rust/ tarnishing. So I sprayed some rust spray on and that's helped a lot with the colour, it's just the texture that's the issue (see pics).
Is there anything I can do to fix it? I really want to fix it and then send them an email saying that's not what I said and am not sure why it's reported that I did, and that it's actually tarnishing from the cheap finish (or whatever), which I've managed to fix.
FWIW, I've been here nearly three years and just wipe them over with kitchen spray and a micro fibre cloth every day as needed. Other things, like my oven handle (different kind of metal) are absolutely fine, so I don't see how I could have caused it. On 10 bloody handles. 🤷🏽♀️
