Best Way To Get Coffee Stains Off Plastic (Melamine)?

[KristalK]

I've just purchased some retro coffee cups from the 1970's. They are melamine, red, with white interiors. The White inside is pale brown with coffee or tea stains. What would be the best thing to get out the stains? Bicarb? Sterident? Vinegar? Dishwasher Tabs? I don't want to harm the melamine . Thanks

i'd go for sterident .

I would try steradent first or bicarb. Give them an hours soak before washing.

I have used very diluted bleach or steradent before. it does work and not ruin.

3 nil to sterident lol

Thanks folks -suppose I will have to go buy some sterident unless I can think of anyone local who has false teeth lol! I have some Hydrogen Peroxide 10% in the medicine cabinet would that be ok?
