Hi. Recently bought a hostess warmer HT6030. I didn't realise how big it was. On the Argos website it was small with a couple of very small pyrex dishes on it. I have used it but it is covered in rings where everything was. I have tried hot soapy water but can't shift the marks. I would like to care for it and keep it in good condition without rings.
TIA
Desmond.
