Frankly, I will not use GSE.
And by GSE, I don't mean "grape seed extract". i mean what they are calling grapeseed extract. The stuff that doesn't actually have anti-microbial properties until they put the benzethonium chloride in it.
Money-making scam aside, benzethonium chloride should never be taken internally. This is fine for you and I, who could conceivably use it as a disinfectant on surfaces, because we don't walk around using our mouth as a hand, like our parrots do.
Not to get too preachy, but I know how to read material data safety sheets, and this stuff scares me.
You would be amazed how clean you can keep your cage with a putty knife (metal blade and PLASTIC handle, NOT wooden), spray bottle of warm water and vinegar, paper towels, a toothbrush, and a steam cleaner for disinfecting. (Don't use sponges...they seem very convenient, but there isn't an environment on Earth more favorable for nasty bacteria.)
The trick is just to clean a little each day. The whole cage doesn't have to be surgically spotless every day. I tend to clean one face of the cage spotlessly every day or two, in a rotation. It takes 5-10 minutes a day, even if you add in changing the newspaper at the bottom. It keeps the whole cage in a remarkably clean state, given how messy a bird can be (Coming back from a week's vacation where the sitter only feeds, waters, and plays with the bird, but doesn't clean is fun, huh?
)
