2 X Cup Clean Stain Remover 1 x 350g for Flasks Mugs and Cups

Does exactly what it says it does! Brilliant product

Used this product before so was happy to find online.

Cannot fault this product, bought it to clean my work flask as it was starting to taste a bit funky, 1 tablespoon and hot water and my flask has come up like new inside wish I'd taken a picture before and after, definetly recommend it.

Have used this product for some time now. It does a good job, cleaning persistent tea and coffee stains from cups, coffee pots, vacuum flasks and other stainable products. Very easy to use. Put a teaspoon in a cup, add hot water and leave for a bit. Th packaging has been re-designed since I last bought it, and I found it slightly difficult to get the lid off, but probably my old fingers. Good product.

I drink constantly from two different types of stainless steel travel mugs. The build up of tannin and staining on both is usually pretty bad, but using the Astonish powder, leaves them totally clean, removing the build up, sometimes there is a need for a brush to remove the sludge which can lingerI would suggest only half filling the container initially if using very hot water as the reaction can be very vigourous. Once it eases off, then top the flask up. Be mindful that this liquid is potent and can remove the outer paint after regular use

Absolutely brilliant I would recommend to anyone

This cup ect stain remover is brilliant. does exactly what it says on the container.

The packaging was broke so when I opened this I lost quite a lot the product very good

I love it

Nach Einwirkzeit waren alle Teereste fast weg. Ich habe gestern den Versuch unternommen Kalk am WC zu entfernen. Ich habe das WC von innen richtig „befeuchtet“ und dann den Entferner aufgestreut. Nach ca. 4 Stunden sind auch hier die Kalkreste verschwunden.
