• If you want to clean the flaxseed, spot clean it with a little bit of soap.  Do not submerge it directly into the water.
• If you want a longer heat time than 30 minutes, wait for cap to cool down and re-heat.  Don't re-heat over 90 seconds.
• Do not submerge the cap directly under water.  This cap is as natural and eco-friendly as it gets.  It has flaxseeds inside them which are the best natural heaters, but if they are submerged in water they will mold.
• Make sure to use the thin shower cap underneath the flaxseed cap.
• Do not heat the cap past 2 minutes.  Look at the tag on the cap for all cautions.
• This is my favorite cap I bring it on vacations and use it while I'm studying and I never have to worry about sitting in one place.

Caution

• Watch the cap closely in the microwave.
• Do not heat in microwave more than 2 minutes at a time.
• Risk of fire.
• Touch test to avoid burns
• Do NOT heat in conventional oven, stove top, or toaster oven.
