Mr Muscle Oven Cleaner (Monks Hill CR2)

I am clearing a kitchen cupboard and I would like to offer this before I throw it away. It seems to have contents although I’m not sure how it opens - maybe you have to break the seal? And I honestly don’t know how old it is, but you could give it a try if it would be of use to you. I am not using an oven so this is surplus. However, if you want this you MUST confirm to me that you’re over 18, as it is marked as a chemical. Please let me know when you could collect, you can have the furniture polish too, if of use. (Listed separately.) Thank you.
