What's the best way to remove coffee or tea stains from my cups and beakers?
Here are some tips to help you remove coffee and tea stains from your cups and beakers:
Tip 1: Dissolve a denture tablet or dishwasher tablet in hot water and leave it in the product for 24 hours. You can repeat this process a few times if necessary. Never use anything abrasive like cream cleaners or scouring pads. This will damage the product and make stains build up even faster.
Tip 2: Add a squirt of lemon juice to the product and fill it with boiling water. Let it stand for 24 hours. You can repeat this process a few times if necessary. Afterwards, brush off the deposits with a washing-up brush.
