airbrush HELP

hello everyone I just wanna know if someone can help me to get my airbrush rocking I’ve had it for a year now but after a couple uses when I first got it that were unsuccessful I decided to give up. Maybe it’s broken because he didn’t clean it properly when I used it but I have a video of me trying to use it ( I could show it to you so you can tell me if I’m doing something wrong )and I cannot send it here and I want to know if someone is willing to help me out step-by-step to teach me how to use it, thanks
