Airbrush cleaning kit should I invest in one

For a cleaning station I made one with a half pint jar with a plastic cover. I then cut a couple of sections of small diameter plastic pipe.  One length is glued to the top through a hole I drilled in the top (OD of pipe).  I use a 45 degree elbow between the two sections of pipe. I spray into end of the top section of pipe- spray runs down and collects in jar.  Since cleanup is mostly thinner, I have used it for a few years, never had to clean or empty jar- the thinner just evaporates between spraying sessions.

I also use a cleaning station I got from Hobby Lobby for about $12 with the 40% coupon. I usually just run windex then water through it after paining acrylics, or airbrush cleaner then water if shooting enamals.

not a kit and I'm no expert but I like using...

Sparmax/Iwata-Medea Cleaning Station (good for keeping the vapor down)

Iwata-Medea Airbrush Cleaner (this one is convenient for me cause it's much cheaper at local shop than online).

REGDAB Airbrush Lubricant by Badger (good cheap lubricant).
