About home brew airbrush cleaners

[CY343491]

Hi,
I see many guys home brew AB cleaners by mixing windshield washer, water, IPA and glycerine. I've also brewed a small batch to try and worked good for me on acrylics. Now i have a question, what type of windshield washer will be better? Some includes antifreeze some not. I know that antifreeze icludes propylene glycol, will it increase effectiveness of cleaning acrylics?

Propylene glycol is used as a retarder .
It has no use in a cleaning mixture .
It's used to lower the freezing point in windshield wiper fluid .

Acrylic resins are easy to dissolve .
Alcohols and ketones make short work of it .

I think they put glycerine to lubricate needle and nozzle, by the way what's the difference between propylene glycol and glycerine?

You seriously think anything is left behind on the needle after cleaning ?
Not much of a cleaner .

Most if not all airbrushes - pretty sure it's all of them - use a Teflon ( polytetrafluoroethylene ) bushing around the needle .
No lubrication necessary .

Thanks. I saw some lubricant products that people lubricate their needles after cleaning. I'm not sure but it was iwata or badger.

Yeah .
Makes no sense to me .
I've never used any lubricants on either of my airbrushes since I see no need and they still operate normally after all these years .
... I guess if you want lube in the coatings you're spraying it's a good practice .
