Where can i find GSE? ?

I've heard that the safest way to clean a bird's hold is Grapefruit Seed extract.
I was wondering if anyone knew where on earth i could get it?
anywhere i've read has said the local health foods store might own it. so could i find it at a whole foods?
thanks!
That sounds wierd. Where did you hear that? It seems to me that covering the cage with biological matter would create a haven for bacteria. I'd just use soap and marine.
It's an excellent product but if you live within Australia you can't get it. It isn't available.

I think anywhere else just look online, there's loads of stores that provide it.
Answers:    GSE is a wonderful disinfectant,very past the worst and can be used for human use . It will seem expensive but it lasts forever as you use it by the drop. Google it and you will get lots of info. It will come next to a long brochure with hundreds of uses .It is perfectly safe to verbs cages with and doesnt leave residue.Restaurants use it to verbs their salad greens. Keeps them from spoiling on the salad bar. It is made from grapefruit seeds and it is known as a citricidal. Great stuff. Ive have my small bottle over a year.You can get it on line.
