So the answer is " don't buy it unless you know what you are doing". people should not be asking on here then sploshing it everywhere. If you cannot write Rams for its use then you should not buy it

And if you are unaware of the PH scale then thats another reason why you should not buy it - if just for your own safety

15% bleach has a PH of 13 ..the scale ends at 14. ...it's gonna hurt you

15% of which bleach measures 13 on the pH scale?  Who told you was it Emma???

On the subject of Hypo, could someone please give me a recommendation and a possible link to supplier for a hand pump sprayer suitable for Hypo? Do the seals need to be a special material or will just a regular pump sprayer be suitable?

Thanks in advance for any help

Having read previous posts do you really want spray it?

Cheers Chris, handy to have a wee sprayer for some spot treatments now and again! that one you gave a link to wee bit more than I was hoping or wishing to pay! I was hoping for a £40-£50 special! Thanks for your reply, appreciated - Gavin

Do you have £40-50 eyes? 
If you must use it (bleach) use a brush.

Can anybody tell me what the dilution ratio is for 14% hypo?

[concept]

As far as I can see, the dilution ratio is up to you depending on what works on each job.

I've been told 1:3 or 1:4 by a couple of people now, so I'd start there, or even less, like 1:5, and see what the results are like.

But hey, no-one uses it, so I couldn't have been told that
