I have a bottle of BLC (Beer Line Cleaner) from the US but in future I'll probably just use Antiformin (it's a strong caustic bleach) - you can get it from homebrew shops (at least you will when Clive's got some bottles that don't leak).

My early brews tasted like washing up liquid, and i fancy it was becuase i was using tablespoons of VWP instead of teaspoons.

Naughty me.

I'm going to switch to either really cheap bleach, or the Rx type product DaaB recommended in my steam cleaner thread.

I've looked for these soda crystals, but found them to be illusive. I had thought that wilko would sell them, since they sell things like generic borax and bicarbonate of soda, but no soda crystals.

My local Londis sells "thin bleach" in a 2l bottle for 99p, and is "<5%" bleach. 75 ml of cheapy bleach has got to be cheaper than 5 tsp of vwp, and if it rinses easier i'll be well chuffed.

If it tastes chemically this time i'll know what i did wrong i suppose.

As you say, vwp does certainly do the job, i think i only soured one batch, and it was becuase i forgot to sanitize the lid of my fermenter i think.

Both my local Tesco and Sainsbury sell soda crystals at 56p / kg
If you have a Lidl store close to you 5L of thin bleach can be had for about £1 :D

Try looking at your feet, they're usually that low down on the shelf hoping you buy something else (more expensive) instead

i use antiformin for cleaning and i have had no problems with rinsing it off. one rinse with water generally does the job. if i am going the non rinse way (depending on what i am sanitizing) i just rinse with paracetic. it neutralises the antiformin and doesnt need rinsing it self.

ps i know what you will say that we all have different methods/experiences/etc i am just saying what i find

This reminds me of a question I've been meaning to ask - how long can dilute iodophor (or betadine) be kept for it to remain effective?

The yellowing seems to dissipate quite quickly and although it's seriously cheap to use and dump, I want to make sure I haven't missed an easy opportunity to make it go even further!

FYI, concentrated form will detonate after 110 degrees celcius.
I think Steve will be able to confirm!

It's not available in homebrew shops and a bloody good thing too as it's pretty nasty. The last thing you want is people who are not aware of how careful to be just buying some in a shop.

That being said it's OK if you do know the risks - Wear gloves and eye protection when using undiluted, pour in a well ventilated place (outdoors is good). Keep cold (I've got it in a fridge).

Diluted it's fine but I still wear gloves etc just in case.

It is unstable at high temperatures and the shelf life isn't up to much - the undiluted stuff has apparently a couple/few months shelf life. The diluted stuff a couple of hours. The explosion risk is lower with the 5% stuff but I wouldn't like to perform a test to find out. :wink:

You could leave it in the beer if the yeast could ignore it, and market it as Blasting Cap Bitter.
I don't know it'd do too well in the shops, though.

It's no-rinse amazingly enough. So you probably already have drunk beer with peracetic breakdown products in it.

I know for a fact i have, since my friend's brewery uses it. That's where i was going to get the dilute from.

Basically, i ask him nicely, he has someone mix me up a batch, and off i pop.

I wear gloves when i handle it. I'm paranoid already, and i've seen what it does to metal spray tubes.

Ta!

Great tip, thanks!
