How do you clean Viton O rings
In most cases isopropanol is sufficient.
Acetone should not be used to clean the o-rings.
Although acetone should be ok to use with PFA, it will attack the latex in gloves, which may then carry over to the o-ring.
Isopropanol, but not methanol or acetone, can be used to wipe Viton o-rings clean..
