I have a pressure barrel that has stains in it I cannot remove, I've tried soda crystals overnight and sterelisers. As they're still there will they affect a new brew. Cheers in advance. Newbie.
 
Assuming it's a plastic PB, best answer would be bleach. 10-20ml into the PB and fill all the way with cold water. Leave overnight then rinse thoroughly.

I wouldn't expect the staining would have too much effect on the beer though - if it can't be removed by cleaning products, I'm not sure the beer will remove it!
 
No it won't. Just make sure it's adequately sanitised.

You should see the state of my FV - not so much stained as a thick brown crust!

It could be Beerstone.
Or it could be The Creeping Death due to your sparge water being too metallica.
Joking aside, it could well be beer stone which is of a far more complicated and problematic than simply calcium oxalate as the above thread would appear to indicate. I've used beer stone remover (BS remover from the Malt Miller) and it hasn't made much of a mark on it- even when used full strength.
I agree with -Bezza-. Get some bleach in there, use five litres and fill the barrel with rather warm water and leave overnight. Don't put anything in with the bleach unless you want to be gassed with chlorine. Do it outside if you can.
I found that this reduces the deposit a little and in any case will ensure all the nooks and crannies in your FV are nice and clean.
Rinse out (be careful where you dispose of the dilute bleach) and rinse again with a solution of sodium metabisulphite. This should take away every last trace of the bleach, which would otherwise taint your beer.
And Bob's your uncle. 5 litres of bleach costs 99 centimes here and I can't imagine it costs much more in the UK. (Use the cheapest, unbranded, thin bleach. You don't want soaps and perfume in it).
 
Beer stone certainly is complicated issue @An Ankoù and why I'm sceptical about that BS Cleaner, with it being a single product to tackle a two faceted problem. The mineral and organic components of Beerstone need tackling individually in my experience.

Best sort it now, before it Fades To Black.
 
Ahh, the old, I get away with my kit being filthy, you will too, advice. Classic.asad.

I guess, that the OP has asked the question because their instinct is telling them that all isn't right.
Nobody said anything about kit being filthy. I get tired of people telling me I'm `getting away with it'. I'm not the one getting infections in my brews... Haven't done so since I started brewing in the 1970s and don't see why it'll start happening now.
