These sodium azide worries seem way overblown. I used to use it daily working in a research lab to keep microbial growth out of the samples. Sodium azide powder is a bad chemical but 20 mg/kg is eating ~1.6 grams for a 175 dude to kill half of the dudes. The solution is likely < 0.1% sodium azide. Nothing to worry about. This is not the issue to worry about.
Agreed to not throw caution to the wind. However, making claims that are easily provably false for people with small amounts of experience in that field make this forum look bad.
The does makes the poison. I've worked around a chemist who had a hook for a hand. She blew her hand off with sodium azide powder. I'd never want to be around a bottle with 50 g of it in powder. However, a bit of azide to keep microbial growth down in a 1 mL solution is not a big deal. But yes, caution is cheap and there is no reason to take the risk. Use PPE.
I would also test a few nasal sprays/cough syrups. Things what you use when you have a cold, and applied to/touches the same sites where you would have to take a sample.
Anything with an acidic pH will cause a false positive because it disrupts the testing mechanism.
So my suggestions of things to try are: lemon, lime, kiwi, orange, vinegar, grapefruit, cola

If you don't follow the instructions, you can't claim they're fucked up.
That would be like putting water in your gas tank to prove that your civic is a piece of shit.
A pizza box
Test liquid dish soap, straight out of the bottle. Or laundry soap.
Pls do the phones. hopefully bots will stop using their phones and unintentionally disconnect from propaganda
