use water, dont use grease on windows, i know you can use graphite but i forgot if its on the track or what part
Water, as well as water-based lubricants, will only lubricate short term, as in minutes. Water is technically a solvent, but it could be considered a lubricant depending on the context it's used, such as within the human body. But in this case, water will not suffice. Both white lithium grease and silicone spray will lubricate the rubber tracks, but the white lithium will last longer in my experience.
The best way, IMO, is to take off the inner door panel; spray the grease into something like a clean plastic cup, and apply with a clean finger or Q-tip in tight areas. Also apply to the vertical track all the way up to the top of the door. If you apply too much, you may have to clean off your windows with the first 20 or so roll down/roll ups.
Silcone spray comes out more "WD-40 style". If it's all I have at the time, I will spray a conservative amount at the top of the tracks, front and back, and just let gravity take it down. With the silicone spray, I definitely have to clean the windows for the first several open/close's.
Silcone sprays, such as 3m's, will boast "rubber safe",, but I have never had the white lithium harm the rubber tracks in any way. I always do it once a year, and never have any problems, especially considering the fact that I also have 2 DEI 530t window modules controlling all 4 windows.

You dont want to use grease because it will attract dirt and dust and eventually be a worse problem then what you had before.
This is generally true, but unless you are living in a perpetual dust bowl, and your windows are ALWAYS down, the dust attraction will not be enough to affect it. In the end, though, you cannot 100% prevent water, dust, or contaminants from getting in there, which is why a yearly cleaning/lubcricating is something I do and never have any window problems.
