Smartseal Brick Acid Cleaner - Easy To Apply Effective Brick Cleaner Solution For Exterior Brick Walls and Masonry Surfaces - Removes Efflorescence, Dirt, Grime & Limescale (5 Litres)

Does a great job of cleaning up the bricks

Plenty of brick cleaners on the market but this one certainly did a good job, it is effective at dissolving mortar stains, would recommend this product.

Does what it says on the tin.

Gave a couple of coatings on the wall with this stuff, worked a treat

Didn't remove concrete stains from brick face

I had some efflorescence on some brickwork following a roof leak. The Brick Acid Cleaner was supposed to clear this, but after three applications - all neat - over three days...can you see any significant improvement? I can't. I spoke to a builder who advised that brick acid fizzed years ago when applied, but you can't get the right stuff now due to 'elf and safety. He has advised trying neat bleach which I will try. As to this cleaner, it's useless for bricks. I might slosh it over the patio, but it's a waste of money overall.
