HF is no big deal, haven't you watched breaking bad? Piece of cake, just use plastic containers. What could go wrong?

Its actually easy to dispose of, just neutralize with calcium carbonate (forms safe insoluble calcium fluoride) and dispose of down the drain or in the trash. Just don't get it in on your skin in the process. There are other options to neutralize as well.

I was surprised to find that 1% dilute HF is both adequate to purpose, and safe to handle.

Safe is relative. I'm such a genius that I managed to injure myself doing a reaction with a single reagent, namely, making amorphous plastic sulfur. I accidentally caught the sulfur on fire, you see. If you ever find yourself in this situation, resist the temptation to try to blow it out; you will regret inhaling near a sulfur fire.

Low concentration HF is frequently uses in artistic glass etching. With reasonable precautions it’s not more dangerous than cleaning your drain with caustic soda. Just don’t be stupid.

What matters is that if you splash some on your hand, you have time to rinse it off before the flesh melts off your bones.

Tl;dr Don’t listen to amateur forum advice, get informed at professional level.

Long: Please, In general I suggest for anyone dealing with chemicals to read the safety sheets to the very least and ask for professional advice.

Very often you will find second order effects at play (teratogenic, cancerogenic, allergogenic, er cetera), as well as dangerous surprises that can await you in reactions.

HF is a very nasty chemical that not only does funny stuff to your bones but can kill you making your breathing stop. Rinsing off your hand does not help in this case, you will need to get a specialised treatment in hospital. We lost two students at the University of Marburg in Germany to HF exposure.

Yet, I doubt that it was 1% HF solution, as may be purchased in any hardware store, that they were exposed to.
