How to clean stained mugs

[Bbq1]

I have a number of fairly new mugs that have stained badly inside due to tea. I have tried soaking them in bleach but it didn't help. If anyone has any tried and tested methods they can pass on I'd much appreciate it.

I've always soaked my stained cups in a sink of sterilising fluid/tablets (Milton or a shops own works) and they come out clean every time

I use the oxi action powder for laundry, a teaspoon of powder in each mug with hot water.

Astonish it’s about £1 in the cheap shops

Bit of paste, quick wipe and they’re clean.

Milton for me too.
Bad stains sometimes use baking powder and vinegar but that's more on pots and things.

Have you tried rubbing the stains with bicarbonate of soda on a damp cloth?

Bicarbonate of soda made into a paste with lemon juice and scrub the cup. I learnt that trick when I worked in a little cafe 20 years ago and it’s always worked for me.

Dentures cleaning tablets

I use a couple of denture tablets left to soak for a couple of hours, overnight for bad stains

Magic sponge

Bicarbonate of soda and white vinegar (although malt works ok too) small amount in bottom leave until stops fizzing and then wipe round with abrasive washing up sponge and wash as normal
I cleaned DHs heavily stained work mug like this and that went from something that should be binned to sparkling.

Dishwasher!

Do you have a dishwasher? Ours are never stained. If not, use some washing powder.

Salt and a good scrubbing.

rub with salt and tiny tiny tiny (like a damp finger) bit of water - v. cheap and no chemicals

Scrub with lemon and salt or bicarb

If hard water area consider a lime scale remover

Thanks everyone, so many great ideas. @BearGum we don't have a dishwasher due to having a small kitchen. @thevassal and @TaraR2020 I will try your options first tonight as I have lemon and salt available. Thanks.

Milton here

Few drops of bleach and water and leave to soak. My once reliable dishwasher has stopped getting stains from mugs recently despite all the normal tricks.

Astonish paste works for me too

Fill with water, good drop of bleach . Stir and leave for an hour then dishwasher afterwards !

Very salty water for a bit

Salt the cheap salt 30p for huge container tub type, tiny tiny drop of water rub in with finger

Soda crystals and hotcwater. Leave to soak

Use the pink stuff paste and a microfibre cloth and give it a good scrub.
