I bought a special bottle to keep my drinkable yogurt in a safe place. 

There is a section in the product description saying:

> 
> Do not use detergent containing **bieach** or **abradant** and any other rough
>  material to clean this product.
> 
> 
> 

I understood what they wanted to say, because we have similar words, in Italian, but i tried to search on the internet and it looks like in english they don't exist at all except for abradant which appears in some minor translators but not in the most famous

I would like to understand if there is something missing.

Abradant is something abrasive as i understood but bieach?
