Anti-Slip Serving Tray 2 "Great for serving drinks but stain if food is spilt on it." Ann 28 July 2015 I purchased 2 of these trays one for myself and one for my Mother. To date I have only served drinks on mine and therefore not had any problems with stains. My Mother however has used her's to serve food and it has stains all over the rubber. I have tried to wash it in warm soapy water but the stains do not come off. Mum is very disappointed with the tray and has reverted back to her old trusted tray. A note from the team We're sorry to hear you've experienced this problem, our buying team have recommended the best way to clean this product is to use hot water, washing up liquid and a scrubbing brush or scourer - we hope this helps.
