There is a good bleach dilution calculator here Chlorine Dilution Calculator | Public Health Ontario
A good rule to use is ppm x soak time in minutes = 15,300. This will kill Cryptosporidium which is extremely chlorine tolerant. 50ppm for five hours or 20ppm for 12 hours

If you are worried about bleach taint.A rinse with sulphite (campden) solution will instantly remove all traces of bleach and also act as a second stage sanitizer.So win win.
Of course its important to avoid bleach that contains perfumes,thickeners, and surfactants . Sulphite wont do much against these.

I've just given all my bottles a deep clean for similar reasons. The usual brush clean followed by a 30min soak in a diluted bleach solution, rinsed twice, then filled with water and left to stand for an hour sorted them out: visibly cleaner than ever before, no detectable bleach taste in the beer. In fact, I've done this with the last 3 batches and no problem at all, going to try it on my old pressure barrel now to see if it fixes the issues with that.

Putting bleach into your brew cannot be a good idea can it?
No. I ditched the brew but was able to use the PB another day.

I just thought you were being thick!Ha got you
With regard to tap water being sterile, you can buy tablets for measuring free chlorine. If you put a DPD1 tablet in a white cup or in a glass on a white surface, any trace of pink shows that there is still some free chlorine in the water. This means there is no bacteria. These tablets can be bought on eBay or from swimming pool/Jacuzzi/hot tub suppliers. You don't need the Lovibond or Palintest comparitor.

I give the bath a good clean then fill it up with a few tablespoons of unscented thick bleach and clean all my stuff in that. I rinse everything in the kitchen sink and do a quick taste test as I pour out. No issues so far.

There's a lot of talk about panic rinsing to get rid of the last molecule of bleach, and then sanitising.
It's enough to rinse reasonably well and then rinse again with sodium metabusulphite solution. This will destroy any remaining vestiges of bleach and is, itself, a sanitiser.

Yep, bleach -> metabisulphite -> star san. There's not much will survive that sanitising triad, and no worries about chlorine.

Well my brew is now I bottles. So see how this one pans out. Thank you all for your comments. Much appreciated
Tap water isn't sterile...it's just clean "enough".
I looked at the thin,cheap bleach in Asda yesterday...had "perfume" listed in the ingredients so I left it there ..

It's sterile ENOUGH if you are mains water.
What arrangements do you have?
Sorry...I meant mains water as you live in a far away place...DPD tablets, and sodium percarbonate, thin bleach, Fred n Flo baby sterilising tablets, Chem-San and mains water! Why?
