Express.co.uk spoke to Howard Moss, CEO at Astonish about the best products for the job.
The stains inside a ceramic cup or mug are caused by tannins. Tannins are a type of plant compound naturally found in foods and beverages, such as tea, coffee, chocolate and wine. Tannins don’t stain mugs immediately, this will happen over time.
Some people choose to bleach the inside of their mugs to banish the stains, but bleach may not get rid of the tannin build-up, it will only bleach the area.
Many use a scouring pad and try applying pressure, but this is a time-consuming method.
Using Clean and Revive powder, instead, will “banish ingrained stains with minimal effort”.
Howard explained: “No scrubbing is required for an easy clean. Leaves no residue and no smell. Simply add a tablespoon and hot water and leave until cool.”

Astonish Specialist Clean and Revive is made specifically for “tea and coffee cups, teapots, flasks plus much more”.
It’s formulated to “banish ingrained stains that dishwashers leave behind, restoring items to like new”.
If you have several mugs that need cleaning, Astonish recommends: “Adding one tablespoon (15-21g) of product to flasks or pots or half a tablespoon per cup.
“Place stained cups, saucers etc. in the sink or on the draining board as the reaction may be vigorous and water may overflow.
“Fill with hot (near boiling) water and leave to cool for one to two hours. Rinse well with clean water after use. For heavily stained items, repeat if necessary.”
The product can be used on glazed ceramics, glass, stainless steel and plastic pots and flasks – all items must be dishwasher safe. Do not use it on gold, silver or aluminium.
As for how well it works, the product has been awarded a five star rating online from customers.

Gim wrote: “An actual cleaning miracle! I bought this to clean out the inside of my thermos that I use to take my tea to work daily. I’ve had it for almost 3 years now and have never been able to get the tea stains off the inside despite much scrubbing and many products. This worked so well!”
Nix said: “Brilliant!! Bought to clean my flask as I use it to put tea in and it became quite stained. Used this product as per instructions and washed it out after an hour. My flask was spotless!!!! Took it to work to use on the teapots and they came up beautifully too!”
