Instructions
Start by filling the stained mug with warm water, leaving some space at the top.
Drop one denture cleaning tablet into the warm water.
Allow the mug to soak for about 15-30 minutes. The effervescent action of the tablet will help lift the stains.
After soaking, use a soft sponge or cloth to gently scrub the inside of the mug. Stains should come off easily.
Rinse the mug thoroughly with clean water to remove any residue from the tablet.
Wipe the mug dry with a clean cloth or let it air dry. For tougher stains, you can repeat the process or let the tablet soak longer.
This method is safe for most types of mugs, but avoid using it on delicate materials unless you’re sure it’s safe.
Denture tablets are available at various UK retailers, including Superdrug, which sells them for 87p, and Boots, where they cost just £1.
