Well, I will mention bleach, as per several of my previous posts!
Yep, I know it divides opinion. But I have no doubt whatever that:
1. It does an extremely effective job of sterilising most things (it will attack metal if left in contact)
2. Rinsing is absolutely essential, but not difficult if done as described above
3. I've been brewing for over 40 years. At first, I tried a bunch of different sterilisers that apparently the "professionals" used. For the last 30 years I've not deviated from bleach. It works. It's cheap. I'm absolutely convinced it does not affect the quality/taste of the beer in the slightest if used properly.
I was recommending it here to someone on a tight budget. But, I use it exclusively myself regardless of cost because it is so effective. I'd have to trawl back through my notes to see when I last had an infected brew. I think it might be the 1980s.
