i totally agree
it sounds like overkill what you do when it comes to the general laboratory work (agarose gels, bottles for running buffers such as SDS-PAGEs & agarose gels) etc.
i also discard bottles with a massive amount of waterdrops, but we have a huge glass ware stock to choose from, and i am not concerned about the purity after use of our glass ware washing machine
to give you an example, the most concern i will take with glass ware is when it comes to cell culture
i do have to make our cell culture media from scratch, and all glass ware used (flasks, bottles) are washed in the machine, autoclaved with ddH2O and then rinsed only with D.I.U.F water
the cells, which are usualy very picky when it comes to contaminants, are growing really well
