Yowzers! 🤯

What do you use for a solder-sucker, if I may be so bold as to inquire? 😎

I did the first one by hand with my old soldering station and litze. It was torture so I bought this thing: https://www.eleshop.nl/desolderingstation-zd-915.html  There's a newer version (https://www.eleshop.nl/zd-8915-desoldeerstation.html) but apparently that one is more likely to clog up so I got the older model. So far it works fine. For 100 bucks I can't complain, really.

I thought of dumping the whole PCB in pure alcohol in the ultrasonic cleaner

You shouldn't do this because it produces an explosive vapor. Cleaners must be nonflammable to be sonicated.

Thanks. Guess I'm stuck with  8L of pure alcohol. I'll use it in the burner when we make a cheese fondue
