3% is what I've seen recommended. I buy 6% and dilute.
I ask for it at the pharmacy. They keep it behind the counter because it can be used to make bombs. Tell 'em it's for your first aid kit. Or tell 'em it's for growing mushrooms I guess. 
Allegedly, yes, it kills spores. I've seen RR say something along the lines of H2O2 "has no valid uses in mycology" (except for killing cobweb, I guess) so you might want to save yourself the trouble. I give agar wedges a brief dip in H2O2 when I'm transferring them. It doesn't noticeably hurt them though I haven't done any empirical tests.

Approx. 3% H2O2.
Any pharmacy or retailer should carry it near the medical supplies usually in a dark round bottle near the rubbing alcohol.
Yes, if not completely it will damage them almost to the point of being nonviable.
Generally if it isn't for cobweb its not worth using.

Really what country do you live in?
I live in probably the most paranoid ban happy state in the US and I can walk up grab 10 gallons off the shelf and walk out with it without being questioned, hell potasium nitrate is even pretty easy to come by if you know where to look.
But H2O2? I know its somewhat reactive but unless its being concentrated i don't imagine it making anything spectacular.

I'm in the UK.
I believe it's a main ingredient in fertilizer bombs (or maybe liquid ones). I'm not sure which exactly. I'd go do a google search for bomb-making instructions to double-check, but I have a feeling that would be a bad move

Ah, here we go. According to Wikipedia:

Hydrogen peroxide was said to be one of the ingredients in the bombs that failed to explode in the 21 July 2005 London bombings.[46]

Myco, no offence intended, but there's a sticky about finding supplies in the UK, because for whatever reason, things that you'd find in "any drug store" or "any hardware store" in the US (I'm just assuming you're in the US) can be very difficult to find here. Not sure why.
Rubbing alcohol is something I've never seen on a shelf here, and I've looked around.

I get mine from Superdrug for 97p a bottle of 6% solution, just go up to the pharmacy counter and ask for it. They have never asked me about what it's for except for that time I tried to buy it with a pack of codeine and paracetamol pills.

They keep it behind the counter, normally in a draw or cupboard to minimise the amount of light the bottles are exposed to. Also remember in "Modern Britain" you aren't a terrorist unless you are Muslim.

Yep what you mentioned about the London bombings is probably the cause behind it then. H202 in HIGH concentrations can be uses as a monopropelant for rockets or a oxidizer when used properly in conjunction with a fuel source. Interesting.

If anyone asks, tell them you have an infected big toe nail.
Or, a boil on your ass.
They will not want to see it, I assure you.

Well, the UK and probably most if not all of Europe is heavily regulated and controlled, much more so than the US. Gotta love that socialist idealism in Europe. Pretty soon everybody will be forced to buy only certain products from a certain company and only allotted a certain amount of times a year to buy it.
The fact that Europe bans such simple items that can be easily found anywhere in the US is just another way to control the people. Be thankful you still have a choice in what you can buy and where you can buy it, because it won't last long. Hell the way our commie president is running things now we might lose those freedoms sooner than you guys. Which would be a first in world history, since the US usually trails Europe by about 10 years in politics, laws and regulations.
As far as the OP question goes, I use 3%. I use the stuff for a ton of things in mycology, since it is as good a sanitizer as alcohol, yet it also kills/mutates molds and bacterias. It's pretty much the perfect cleaner solution for mycology. Because not only does it kill practically everything, but once it is spent it turns into harmless h2o. So no nasty by products. Probably would be great for sterilizing syringes without boiling/PCing them. Just suck up some h202, let it sit, plunge out, and now you have a clean syringe.
I have actually been successfully using it as a water substitute in my BRF jars. So instead of mixing water with verm and BRF, I mix h2o2, then let it sit for a few hours. Then once I sterilize it, the heat breaks down the h202 and just leaves h20, ready for inoculation. Can't get any more sterile that that.

Are you going to start with the offtopic political shit again nanoid?  Take it to OTD please. Please.
It's not because stuff is banned. I don't know where you got that from, but I imagine your fevered, paranoid political rantings were just busting to get out, so you didn't take the time to grok what anyone was saying.
For example: people in the UK don't really do canning. So finding PF tek-style jars, Mason jars, pressure cookers, etc., is a little more difficult and/or expensive.
It's not a communist plot, guy.

Well, maybe not from the lack of canning jars or H2o2, but there is definitely a communist one world government control plot in the works. Of which Europe has always been in the lead. But our terrorist foreign president is surly changing that...

The LIGHT breaks it down. This is something to keep in mind when diluting 6% to 3% as decomposition is fairly rapid. Great idea about using it in syringes though, I will defiantly be trying that out.
Also can we clear up this nonsense about hydrogen peroxide and bombs. It is NOT a watched chemical and sales are not monitored. If you buy a bottle everyday for a month they might start asking questions but apart from that I promise you, they will not care.

I wish i had a nickle for every time I've heard this rant, I would be one rich a$$ motherFucker.

In the pharmacists where I've bought it, they keep it behind the counter and you have to ask for it. The very first time I ever bought some, the lady asked me what I wanted it for (because, she explained somewhat reluctantly, it could be used for bombs). I told her the truth and that was that.
I don't know what a "watched chemical" is though, or whether she had to ask me that, or whether she was just trying to be a responsible vendor, or whether she was a nut, or what. It's just my experience.
Anyway there doesn't seem much point in continuing to bash on about the shelf-stocking habits of UK pharmacies. It's available, you can buy it.
