What would the group suggest?
Brick acid and a paintbrush. Mild acids will work but take forever.
What IS this brick acid that people keep referring to?
I've heard of hydrochloric, sulphuric, nitric, formic, citric, and of
course "aceeed"(!) and others, but "brick?". It doesn't sound a very
scientific name.
Its HCl, maybe with some oxalic acid thrown in. Good for cleaning
mortar off bricks, rust off plastic, and the strongest scale remover in
the west.
The point being that it's sold under the name "brick acid" at your local
builder's merchant or even B&Q, for the purpose as described above
