Home made paint cleaner

I'm not sure about any recipe,I just shoot 91% ISO alcohol and it cleans it fine,also Lacquer thinner will clean out old dried acrylics.

Thanks Tojo72, I have tried doing that and found it turned paint to a thick gel. not sure if its because its 99%vs the 91% iso, I will give it another shot. Thanks agian Rory.

The trouble with acrylic paints and thinning them is the variety of formulas with different brands. What thins one brand, may turn another brand to gummy goo. And there is no one stop universal thinner for all acrylic paints. Although lacquer thinner can be used with many different brands. But for those who opt to use acrylics to get away  from smelly chemicals with enamels, this completely negates that point.

I can't say a lot of us make our own "home-made thinner" but we all use what works best for certain types of acrylic paints. As stik already mentioned, one may work on one brand  may not on another. Not all thinners are the same. I know using alcohol on Vallejo paint turns it into a gummy mess. 

Thanks for all the info Gentlmen, I have found A mix that seems to be working well for me. I use Vallejo air and VA model color 90% of the time, being fairly new to this hobby Iam learning as I go so once agian thanks for the help.
