Acid washing Liquidator lines

[Water_man]

I'm sure some people have already acid-washed the WS off their LQ lines.
How do you pour the acid water into the narrow orifice of the tubing?
Do you use a syringe or a funnel, and if yes, where do you get them?

Soaking the tubes in a large plastic or glass bowl of acid is probably the simplest approach. Lower the tube in from one end, so it fills up completely, and then remove the end that went in first and pull it out slowly so all the acid drains out through the other end.
