how to clean soldering iron tip

What is the name of the product called Bit Tip Thinner? Are the fumes from this product are harmful if inhaled? What about fumes emitted by solder metal and flux?

Flux?

I found this channel randomly; it is really a channel that produces quality content

Do cheaper soldering tips get forty faster??? Mine is super cheap and needs SO MUCH CLEANING

Can i use solder wick instead? The tip tinner is very expensive for me
