Hydrogen Peroxide

Post by Reg » Fri Apr 21, 2006 9:10 pm

Just thinking on the whole streilising thing, I wondered if it would be worth starting a debate about alternative sterilsing agents.

An example would be http://www.wholisticresearch.com/ecom/p ... prodid=358.

Now I'm picking this one because I feel it's pretty easy to tick off the list.... It's expensive and degrades naturally over time so doesn't store well. It's plusses are it degrades naturally over time... ;) (It's biodegradable), and is food safe, but on the whole it would probably be a pain in the posterior to store and use plus it would cost alot.

I can think of a few others, can you??? :huh: :blink: :unsure: B) :rolleyes:

Used in agriculture, eh?

I happen to know an agricultural merchant, who I will hopefully be seeing on Thursday. B) B)

QUOTE (Daft as a Brush @ Apr 22 2006, 11:28 AM)Of course there's Iodophor too, available from Brupaks at around £4.50 for 250mls or from the chemist sold as Standardised 'Betadine, antiseptic solution' aqueous.
It may have to be ordered in by the chemist but at £3.50 for 500 mls its worth it. It needs a 10 min contact time, doesnt require rinsing and works well in a hand spray.
The required concentration is 1/2 tsp to 1L luke warm water, it remains effective all the time the solution remains amber in colour. It must be used in the correct does, too much  and it actualy looses its effectivenes.

I really recommend this stuff, its cheap, easily available, no rinse and effective, I beleive it is also used by the agricultural industry.

Well, this stuff sounds really interesting. Particularly if you can use it as a surface spray --- a sort of all-in-one product has its attractions from the point of view of simplicity. (Which I like becasue it makes things easy and because I'm simple :D )

However... :rolleyes: :P

I use Betadine, got Boots the chemist to order it in, cost just over £3 arrived next day.

At the concentrations you need and the short contact time I've not found staining to be a problem. I use a litre garden/plant sprayer with 0.25-0.5 tsp of Betadine and a litre of water. Just spray it on to surfaces to be sanitised, leave for a few mins and then drip dry. The solution in the sprayer lasts a week or so, I keep it until it loses its colour.

It's excellent stuff and a 500mL bottle will last for years.

I'm a bit worried about contamination of the taps on my fermenting bins whilst there is wort/beer in them. Presumably if I just get some betadine I can just spray it on in diluted amounts, or soak the tap in a glass of it (long taps!) whilst it is connected to the bin? I then don't have to worry about washing it off.

Also, to get this straight, presumably I can wash my bins with unscented washing up liquid or soda chrystals, rinse, and then spray it with betadine, leave to dry, and then I'm ready to add wort etc.

Is this right? :unsure: If so, Betadine sounds magic - I get paranoid about making sure I've rinsed off all the VWP when brewing.

I had to install additional lengths on the climbing sticks last night as the plant had reached the top of the initial stick.

Well, I had a word with my mate and he not only knew what I was talking about, but seemed to think that he could get hold of some in reasonably small quantities!

Watch this space! B)

Going back to Hydrogen Peroxide, I believe it can be used with Peracetic acid to make a more stable cleaning product...

I know mate, but I'm guessing they add extra H202 to Perastane as a buffer and you get the best of both as the Perecetic decays to make up the H202 as it decays making for a constant hit...
