Scared Of Iodophor

[pint of lager]

Iodophor is great stuff and cheap. Go in a bulk buy with some fellow brewers and have plenty for the next few years. Make sure you understand the difference between clean, sanitised and sterile. Also check the concentration of your supplied product and mix it up correctly.

The full strength iodophor will stain everything, diluted and in the correct concentration, it may give a mild stain to plastic, but this will come out with a soak with bleach or napisan.

Like Ross said, there are plenty of alternatives and we all should change our cleaners and sanitisers to keep the bugs on their toes.

If people are worried about the flavour tainting the beer, sanitise up a fermenter, drain upside down, fill with tap water and then do a blind tasting with the water from your fermenter and a glass of tap water.

Iodine is a necessary part of our diet. It prevents cretinism.

Cant remember the details but I read an article a couple of years ago about a bloke in the States who sat his mates down with a glass of beer and started adding idophor to the glasses and slowly increased the concentration. By the time the iodine was detectable, the concentration was many times over that which you could possibly get using the stuff in normal circumstances. Maybe the brew tasted lousy anyway or they all got pissed.
Anyway, it works for me and I dont rinse. I use 1ml in 500ml only because my squirty bottle is 500 and the smallest I can measure is 1ml

I have a feeling this is the article you are referring to.

I'm one of those who 'swear by' iodophor and no-rinse. Couldn't give a stuff if my ferm fridge, buckets, gear etc. is off-orange coloured from continual iodophor use.

Personally I hate Idophor... I don't like the smell or the way it stains everything.
It obviously works & plenty of people swear by it, but I reckon there are far better products on the market.
Cheers Ross

Ross any reccomendations for non-staining, non-stinky, no rinse options?

Hydrogen peroxide.

How about visit his site, he might even sell a sanitiser

 

[Kai]

"No-rinse" sanitisers generally do require rinsing when used at higher concentrations; I would expect that is the motivation behind the usage advice on the label. I've never used iodophor myself, but even when using a no-rinse sanitiser I almost always follow it with a boiling water rinse.

I use Starsan for soaking & hydrogen peroxide on brew day. Either work great, but Starsan i find best for sanitising fermenters, cubes etc, as it's high foaming & makes coating your equipment with a small amount of product very easy. H2O2 in the spray bottle on brewday for all those little jobs....

Hi Ross

What dilution do you use with the Hydrogen peroxide?? How many mls per litre??

Cheers

i use a product called Hysan. It's 12% H2O2. I dilute it to approx 5ml per litre when using my tank water, but it's effective from 1ml/L using distilled/RO water.

Cheers Ross

Liar !

Oops! Okay, once or twice. Or more if you count the time I tried to "roll my own" with betadine, orthophosphoric acid and detergent.

It's effective at 1ml/L and no rinse at that concentration, think from memory contact time is 20 sec, check out some of the Basic Brewing/Brewing Network Podcasts on sanitisation/iodophor. There is a good Basic Brewing interview with Charlie Tally of Fivestar Chemicals the manufacturers of Starsan, he even advocates the use of dilute bleach (diluted with water first) solution with white vinegar added to bring the PH down as an excellect no rinse sanitiser. No sense mixing a stronger concentration of Iodophor, can't kill things deader than dead.

Further to the above, have been using more Iodophor lately as phos acid is running low, and I use it for cleaning the SS bits in my brewery. Revising the use I listened to the Basic Brewing Podcast from the 22nd March 07 again on sanitising using Iodophor. Merle Landman of National Chemicals who manufacture BTF Brand Iodophor, discusses the usage of Iodophor as a sanitiser for home brewing. He says the usage rate should be 12.5ppm for sanitisation up to 25ppm for disinfecting. At the sanitising rate of 12.5ppm Iodophor is rinse and stain free, at the disinfecting rate of 25ppm it will stain and also should be rinsed if coming in contact with food. So I wondered what rate I'm using it at.

Well if 12.5 PPM thats 12.5 ml in 1,000,000 ml correct? So devided by 1000 we get .0125 ml per Litre thats one 80th of 1 ml. At 25 PPM it is 25ml in 1,000,000 ml and that devided by 1000 to get a per litre rate of .025 or one 40th of 1 ml. If my poor maths are correct then I'm using way too much at 1ml per litre.

What usage rate are others using?????

Retailer's instructions.
Interesting discussion of flavour threshold of iodophor solution.

 

[pint of lager]

It depends on your concentration of iodine.

I use 10% povidone iodine solution as supplied in a Batadine bottle at the rate of 2.5ml per litre. Contact time of 10 minutes. Have a bucket on the brew bench with a fill mark of 5 litres, add 12.5ml using a syringe and anything small gets dumped in the bucket. Fermenters have a litre or so poured in, swished a few times over 10 minutes, then drain back into the bucket, stand fermenter upside down to thoroughly drain and use it wet.

Check what concentration you have on your bottle.

Iodine evaporates fairly quickly.

After hearing the podcast I cut it back to 1ml per litre and do not rinse. I have been using this stuff for years and have had no noticable infections.

1ml per litre here and no infections to speak of.

Am not worried about the effectiveness, only trying to eliminate staining and to a lesser extent the possibility of needing to Rinse.

At 1/2 fl oz (US) thats 14.787 ml per (5 US Gallons) 18.927L. At that rate 12.5ppm I need .781ml/L and 25ppm = 1.56 ml/L so I guess that I've satisfied myself from this information that at 1ml/L I'm less than the disinfecting rate and there is no need to rinse, but I could cut down a little to 1ml/1.25L to reduce staining.

Cheers and thanks for the replies, Screwy

 

[bindi]

.781ml/L OK I am happy to use a little less, made up 5L with 5ml for my brew day today that's 1.095ml too much for 5L.
