Qiaex QX1 buffer composition?

We use Qiaex kits for DNA extraction from agarose, but the QX1
solubilisation buffer always seems to run out first. The handbook
only says that QX1 contains sodium perchlorate and has pH below
7.5. Does anybody have the recipe for QX1 or for a suitable
replacement? We use TAE gels, not TBE so borate is not a problem.
Would NaI work with Qiaex resin?
