I can only say that it will depend on the stain I did get a coffee stain out of a shirt after it had dried in, this product is very cheap to buy and I use it all the time, I would buy another, it will clean windows, bathroom tiles, kitchen surfaces and for the price I don't think you will buy anything better

Hi, I found that too, I found if I pressed it fully inwards and turned anti clockwise it became loose. It takes a fair few turns mind for it to come off. It will come off, once you get the knack for it.
