I have the master airbrush cleaning pot. After using it for the first time this night, I noticed it leaked, A LOT. As I was spraying into it, I could see the vapors leaking out everywhere. It leaked out of the whole that is supposed to let out filtered air from the jar, and it leaked out from a bunch of different places around the bottom of the cap. can anyone tell me how to fix this?

i would say the pot is broken though you probably know that is a fore gone conclusion i would take it back and have it replaced or refunded

I have checked it over and I can say that there are no cracks or defects in it. I just need to find a way to create a better seal around the top. I just don't know what to use to seal it better.

if the gasket is rubber try using some vaseliene or a small amount of oil applied with your fingers and that will make it seal up
sometimes rubber will kink when it tries to seal

I will try that tomarrow.

I hate to be a nay-sayer and a pessimist, but I have the Media-Iwata version of the same type of airbrush cleaner, and frankly, I've found it pretty useless.

The issue is the little quarter-sized filters. They basically clog-up after a single use. Once the filter is clogged (by the paint, etc that you're shooting out of your airbrush), then logic tells you that the air you're shooting in has to come out some other way. Since it can't pass through the filter, it has to pass out from the rim of the lid or right back out of the opening for your airbrush (making a giant mess out of the airbrush that you're trying to clean).

After a few uses, I gave up trying to use mine to clean my airbrush. Now I just use it as a receptacle for excess mixed up paint and cleaning thinners. I suck these out of my airbrush paint cup with the same eye-dropper that I use to measure and mix the paint and then squirt them into my "airbrush cleaning station."

That's about all that I've ever found the thing really useful for.

Frankly, I would say that these types of devices are pretty much worthless unless you change the filter after every use. That's just more expense and additional cleaning effort on top of what I'm already doing.

Maybe someone else has a different experience, but that's mine...

Drop the little filter into some solvent once in a while , if you use water based acrylic then use use hot water and soap . If not then use some Home Depot lacquer thinner . While the pot may be considered useless it at a minimum will contain a majority of the fumes from cleaning the airbrush.
As for the gasket on the lid , last case scenario cut it out of thick card board . The original was really like teats on a boar hog , did not do anything but take up space. So it sealed really lousy .

Try a little water in the bottom...MASSIVE WINK!!

I can see the fumes coming out of the filter too, so it's not cloghged, it just is so cheap and thin the fumes and paint mist just go right through the thing. I have some extra gasket grade cork laying around here somewhere, so I'll see if I can cut out a new gasket from it, and fix the leaks around the cap. After that I'll see if putting all of the filters that came with it or at least more than one in the hole and see if that will fix the problem of the fumes coming out of there.

Sorry to say this but a mist does escape that system. It is the way it works. You can't stop it. It is built to contain most of the liquid but not the fine mist. Depending on the type of solvent you are using you must be careful of the fumes. You will know when the filter is clogged. If you are using solvents you must wear a mask. If it is water (for acrylics) then it isn't an issue.
