Cleaning & stain removal

[starfis]

Hello all

I have stored these cake tins into garage for a long time (see pictures attached) pls how do I or what can I use to remove the stains and get all clean and perfects pls

Have you got a dishwasher? Just pop them in on the next wash

Have you soaked in hot soapy water? Dissolved washing powder would be great.

Scrub a hard dishwasher tablet on them as if you would with a sponge. It'll come off.

@Softoprider yes, used dishwasher but no luck

Used salt, vinegar and bicarbonate soda and scrubbed hard but no luck at all

Did you try the hard dishwasher tablet? You literally wet it a little and scrub.

@PinkButtercups I will try that next thanks

Try some Pink Stuff paste. Try soaking overnight in a dishwasher tab first.
