Will heat affect liquid zeolite – for example, if I leave the bottle in the sun inside my car?
Zeolite is a virtually indestructible mineral that is unaffected by temperatures under approximately 900°F (480°C). The plastic bottles that liquid zeolite comes in are high-grade dense polyethylene that should not leach at normal, ambient temperatures. The only issues would be if they were stored over time above 100°F (40°C) or if they were heated (as in a microwave).
