I've heard that hydrochloric acid (which can be purchased on eBay or Amazon) can be used to remove cement stains from red brick face. Can it also be purchased in DIY stores (I couldn't see it on B&Q or HomeBase websites)?
Can anyone confirm if this is a good product for this purpose, or would you recommend another product?
Thanks.
