If you aren't opposed to buying new plastic, several companies make professional grade, chemical resistant spray bottles and nozzles.  I had a similar question a couple of months ago and decided that was the best route for me (still finishing up my traditional cleaning products, but they have good reviews).  Something about vinegar and essentials oils breaks down the spray mechanism and the chemical resistant ones can stand up to that.  You might have to do some searching, as there are mixed reviews, but it's something to think about. 

By 'Mom n Pop' I meant a specialist small local shop. Like say to buy a metal bike basket.

I'm from England and the large retail bike shops will definitely not have any choice to make room for more day-glo go-faster stripes. Since we seem to regard bikes as merely a fashion-statement for our children than the most efficient vehicle ever invented :(

Eve,

Thank you, thank you, thank you!  There are still a couple of plastic drink bottles in our house (because I engraved my daughter's name into the plastic for school, and can't remove it), and I have been frustrated as, trying to get liquid (bulk) soap from the ceramic holder I bought in place of plastic – it just gets clogged up and my hands aren't strong enough.  Reuse of the drink bottle would solve soap, and shampoo (same problem, not as bad).

I now have so little plastic in the house, but I guess reuse in the bathroom should be alright, little fire risk there.

Thanks again, Eve, and Beth for your columns,

Ann.
