I didn’t know that coke stained glasses. I’ve seen coke used as a cleaning agent before.

I always first try bicarb & vinegar, when that doesn’t work I often have success with a bit of Nappisan and boiled water and I always have Steradent at home for dirty pots, pans, cup and glasses as another option.

never had this issue, but coke is caustic and removes rust so maybe more coke… or bicarb

I’ve never come across coke stains in a glass…but coke imagine coke itself would help remove it…it helps remove rust and stained toilet bowls

I have always used a Steradent tablet it does the trick and leaves the glasses nice and clean and sparkling!

Make a paste of bicarbonate soda and water, apply to stains, leave for a while. Add a small amount of white vinegar to the glasses and top up,with hot water. Leave to soak

Thanks for all your wonderful answers,a huge help!

I use citric acid in the steriliser and kettle, maybe try that wiht boiling water?

I guess this would be like a coffee stain in a coffee mug.. I agree bi carb soda mixed with water and let it sit overnight.. the wash out cup/ or mug.. If that doesnt work the only other thing i can think of is to fill the cup with white king and leave sit for a hour or so.. But keep well out of reach of children. And wash a few times in hot bubbly water.. before use..

Did you try white vinegar with baking soda ?

I’ve never had any issues with coke staining glasses of mine before, always washed out perfectly with dishwashing liquid. Will follow this post.

Hope some of the suggestions helped with the staining?

put some bicarb soda and water in it and let it sit

Make a paste with bicarb soda and vinegar. Use a scourer to rub off stains

Never had this problem. Gumption always works well on stains.

Vinegar or bleach. Wash properly afterwards and completely dry.
