what is this white stuff on my sterilisor?

[kiki22]

I've just brought out the sterilisor to clean and check it's working and the inside parts that hold the bottles are covered in a kind of white powder, I've descaled it and ran a cycle twice but it's still there, if i scrape it with my nail it goes away. I've not used it for 4 years so can't remember if it was there before. Is it still ok to use do you think?

If it's that old could it be the plastic degrading? If not I would imagine it's limescale, give it a good scrub and it should all come off. I left mine for two weeks when we went on holiday and it was coated in it. Once it had a good scrub it was fine.

Four years? Buy a new one.

Just found this thread again.

tbh i did buy a new one myself but i have a friend who is pg and doesnt have a lot she asked for the old one if i was getting rid of it.
