Are you taking some form of antiphyschotic drugs ?

Is it biodebgradable? : In the environment, chlorine bleach (Sodium Hypochlorite) eventually breaks down into water, oxygen, and table salt (sodium chloride or NaCl) – the same chemicals that are used to create it.
one of the reactions to create bleach:
Na+ + Cl– + 2H2O + energy <=> NaOCl (bleach) + H2O +H2 (gas)
NaOCl (bleach) + H2O <=> HOCl (Hypochlorous Acid) + Na+ + OH–
HOCI <=> H+ ClO–
The Hypochlorous acid is responsible for most of the disinfection properties of bleach.
one of the ways bleach can break down:
2NaOCl (bleach) + sun/heat <=> 2Na+ + 2Cl– + O2
The misconception that bleach is not biodegradable comes from the fact that it reacts with organic material in drinking water treatment (and I presume in cleaning as well) to form chlorinated organic byproducts that are not as easily degraded.
"The primary and most consistent finding arising from exposure to chlorite (ClO –) is oxidative stress resulting in changes in the red blood cells. This end-point is seen in laboratory animals and, by analogy with chlorate, in humans exposed to high doses in poisoning incidents. There are sufficient data available with which to estimate a TDI for humans exposed to chlorite, including chronic toxicity studies and a two-generation reproductive toxicity study. Studies in human volunteers for up to 12 weeks did not identify any effect on blood parameters at the highest dose tested, 36 µg/kg of body weight per day. Because these studies do not identify an effect level, they are not informative for establishing a margin of safety."
I am sure soft-washing a drive would work up to a point but it seems to me that most people who clean driveways use high pressure systems for a reason (I wonder why that is ...thinks?!?).
If jetting is not your thing then use a rotary machine with a hard nylon or silicone carbide brush and some water, preferably supplied through a hose as a watering can or bucket would not give you enough flow to remove the debris.
Whats the cleaning chemical and is it safe? Tell them it's bleach and water; because...well..... it is....................... or give it a bulshooitoiut name like 'mosalgocleerer' and baffle them with scientific gobbledegook about micelles and proteolytic enzymes interacting with crystaline zonal rotators within the macrogolic suspension, also mention it costs £50 a litre.
Is it safe. Of course, as long as you're not a plant, animal, piece of clothing, bedbound asthmatic, vulnerable adult or the like. It is also very safe unless you add some ammonia, vinegar, rubbing alcohol. As you are mixing a 15% solution at 1/10 you will get a 1.5% solution which might just sterilise the water so at that level of dilution the effect would be negligible.
