Slightly confused here.
Household bleach is usually around 4-6% sodium hypo.
The strength at which I clean render etc is usually less than 2%. It works.
So I'm surprised household bleach is so much stronger? Amazed there isn't more injuries from daily use.
Or am I wrong here? Is the household bleach 6% but at a lower SH strength?

No your right, you are slightly confused :) 6% active ingredient is very strong and I always point this out to my insurer when they ask do you carry chemicals "the products under your kitchen sink is stronger than I use" is my answer. It's not just sodium hypochlorite that's in your supermarket "bleech" along with numerous agents there's sodium hydroxide as well.

I see,
So we are using a much weaker mix than shop bought bleach.
I find even a 1.5% mix is enough for most jobs, let alone 6%!
Mind you, the shop bought bleach is usually mixed with water to dilute it down, but still, it's strong stuff for joe public to be using daily...

I'm going to confuse everything here !!
household bleach contains ( usually less than ) 6 % - thats 6% of sodium Hypochlorite ( the strength of the Sodium Hypochorite is not shown ) so my guess would be that its 12% strength
when buying Sodium Hypochlorite at 12% your drum of chemical is 100% sodium Hypochlorite if you thin this down say 3 parts water to 1 part Hypo your mix is still 33% compared to household 6% so is 5 times stronger

Totally get that smudger,
I usually dilute mine down to 2-3%, so a lot less than household bleach...

does that actually work at that strength ??

2-3% of active ingredient... diluting 3l of 14% abv down to 3% by adding 11l of water.
Dilutions are based on the strength of the active ingredient, no point trying to over complicate it.

Alan Ritchie is correct...to get 1 litre of 3% SH from a stock solution of 15% mix 200ml of SH with 800ml of water.

Hi Darren, yes it does, for cladding and render it’s absolutely fine. Not for roofs of course.
I use a 60 litre barrel, around 7-8 litres of of SH (14-15%), and the rest water mixed with surfactant. This produces around 3% or just under of SH mix.
