When You Give Your Bong An Alcohol Bath How Long Do You Leave The Alcohol In?

[Little Red Wagon Repairman]

I've got mine soaking now for an hour but I've left it soaking all night too. Is it necessary to leave the alcohol in for a long time or is an hour plenty good enough? I use salt in the alcohol for scrubbing purposes too. Smoking a new batch of Darth Vader OG later tonight.
