(Formerly called Cemex)

Brick Cleaner

Cemelex is a high strength Hydrochloric Acid based brick cleaner containing specialist additives to boost the action and penetration of the acid solution. Commonly referred to by builders and building contractors as brick acid. Cemelex is formulated with the addition of inhibitors to minimise attack on bare metal and modified to prevent excessive fuming which is widely associated with many acidic solutions.

Brick Acid

Cemelex can also be used for the effective removal of efflorescence (white salt deposits on brickwork), and many other stains and contaminants from floors and hard surfaces. Ideal for brick cleaning, stone, decorative stonework and cleaning badly oil stained concrete floors. Will remove rust stains, corrosion, limescale and mineral deposits, etc.
Can be diluted with water up to 10 : 1 for effective descaling depending on the application.
This is the strongest brick cleaning acid available.


Effective - instant results
​Easily removes limescale deposits
​Safe on most plastics, glass and rubber
​Universal application
​Effective in hard and soft waters



Brick Cleaning Acid

Cemelex contains a high strength Hydrochloric Acid (25%) which means that this is one of the strongest formulations available for brickwork cleaning and descaling. Industrial Hydrochloric Acid is only manufactured up to approximately 36% strength due to the difficulties involved in handling and evaporation.
In fact concentrations above 25% require specialist ADR couriers for transportation.
As a comparison most DIY stores and Builders Merchants supply brick cleaning products which typically only contain around 7% - 10% hydrochloric acid, consequently Cemelex is a much stronger and more effective formulation giving far superior performance and results.


Irritating to eyes, respiratory system and skin. Keep out of reach of children. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. In case of accident or if you feel unwell seek medical advice immediately.

Cemelex is one of the strongest Acid Brickcleaners and descalers available and although safe to use, as with most strong chemicals Cemelex requires caution when using, handling and storing.

Really good brick acid. We have tried most out there and this is the strongest and best. First used it in our building renovation business about a year ago and now wouldn't use anything else. It's strong enough to water down for easier jobs which you can't do with most acids so it works out cheaper in the long run. Thanks

Very good product. Strongest I have used.


Bill Watkinson-Sunderland-5 Stars

Brilliant. Have used this many times and it is the best and strongest around. Use it for getting cement off bricks left by messy builders.

Very strong. Much better than the weak stuff in DIY stores.
