Then you are asking for trouble. Milk bottles are designed to work
well for more than the life of the product they contain. And that
isn't very long. I have had many such thin polyethylene bottles
spring leaks after sitting on the shelf for a year or less, especially
if one of the fragile corners has been dented.
The best recycled plastic bottles I have seen lately are the gallon
bottles used to sell Diet Lemon Iced Tea from Nestea (and probably
othe variation, though this is what my wife has been buying). These
can be hard to find, but are very sturdy, compared to milk containers,
especially with respect to strong corners and bottoms. They are
stamped PP compatible (recycle plastic group 5) and group 7 (other).
Of course, there are lots of very good Nalgene and other laboratory
grade plastic bottles available from eBay. Etchant is such viscous
stuff that it is worth getting good bottles to store it. A single
spill can cost way more than you will ever spend on bottles.
