I've removed an old rayburn (type) fire, the previous owner had been using it - though the chimney was almost entirely blocked. As a result the brickwork is very sooty. I'd like to put a multifuel stove in its place but want to clean the bricks first.
Ive scrubed the bricks with a wire brush and with warm soapy water and ALOT of elbow grease! but without much success. Would acid brick cleaner for removing concrete stains work? and any other suggestions?
