I have a large collection of lab glassware that I was given, all used in a high school lab. It is physically in great condition and should work wonderfully in my darkroom. My concern is getting the glass chemically clean. I don't have access to an autoclave, so what are my options? Any chemical cleaners that work well enough? Is it a real concern - can I contaminate my chemistry through trace amounts of things that won't wash out? I plan to use some of this glassware for wet plate work, and don't want to ruin expensive chemicals due to contamination. I also don't want to junk this stuff and buy new if I can avoid it.
