Default Clean beerstone in a keg?

So I am out of PBW and can't get it locally. Tried OxiClean with no luck.

Any other suggestions on what I could use to get beerstone off the fittings of a corny keg?

BLC (beer line cleaner) works great. Ask your local pub to borrow an ounce of it.

Star san it does everything... You can even use it to clean stab wounds, it gets so clean you could toss a dead rat in there sew it up and not get an infection. Yea, it is that good.

Have you ever tried these guys:

http://www.cask.com/main/index.php?page_id=11

Not sure what they carry, but they are local and might be able to help.

Tried a 5 hour soak in Star San and it loosened it a bit. I think I might have to try something a bit more powerful if I am going to get the insides of my tubes and posts clean.

Unfortunately, I can't get BLC here either. But maybe I will try the folks at Cask.com.

Thanks for the tips guys.

Do you have a dairy supply store near you? They sell "dairy rinse" which is mostly phosphoric acid. This should remove the beer stone pretty quickly. Just follow the directions, etc. That is, ignore them and double the amounts of the active ingredient, Red Green-style.

FlyGuy,

An alkaline detergent, PBW, OxyClean, et al, will not remove beer stone.

Beer stone is a mineral build up. You need to use an acid to remove it.

Organic soils are what alkaline detergents are best at removing.

A nitric/phosphoric acid blend is best for getting rid of beer stone, but that is not something to use in a home environment.

Phosphoric acid would be much safer. The last rinse sanitizer used in commercial dishwashers is mostly phosphoric.

You can even try a long soak in a citric acid solution for a few days.

Thanks for the tips Wayne. The parts/keg are soaking in phosphoric acid (Star San) right now. But I might try to step it up a bit if I can find some nitric/phosphoric acid blend.

Cheers!

Cascade Dishwasher Detergent!!!!!!!!!! It's caustic soda in disguise.

One other place you can look. Hydroponics stores sell pH up/down in concentrate.
