hi guys,

do any of you know where i can get i bio degradable brick cleaner from to clean a house and a building.

[Blast Away]

You can buy this from B&Q or at a ridiculous price from their reps if it's what you need to be seen using.

My opinion, it's not strong enough for most mortar stains.

I mix my own.

hi blastaway

how do you mix your own do you water it down a bit? will this bring houses bricks up ok?

[Blast Away]

What do you wanna remove, carbon?

Different chem for carbon. Nothing Bio for this. All harmful HF based.

its just to brighten up some houses outside.

neolith chemicals are very good but even though bio degradable they are still pretty dangerous to use and burn like hell if come in cotact with skin, like blastaway says it is different chemicals for removing carbon. With carbon first a strong alkaline clener is used to remove grease and then an acid cleaner is used to remove the carbon if you try acid on its own it will have very little effect as the grease in the carbon has to be removed for the acid to work, these sort of jobs need to be well priced as there is a lot of prep work to take into consideration ie windows and other damagable objects need to be fully protected as the chemicals used can do irepairable damage to these.
