Did you know that one laundry product causes long (dryer) vent pipes to get blocked? Blocked or partially blocked vent pipes pose a fire hazard or a carbon monoxide hazard if it’s a gas dryer.
Fabric softener sheets leave a slightly sticky coating on the inside of the vent pipe, then the next time the dryer is used the lint sticks to this and the cycle is repeated and repeated, the rest is history.
If your vent is on an exterior wall you may be able to check your pipes condition by looking into it using a flashlight.
A long pipe for the softener sheets is any pipe that’s more than five or six feet without elbows (turns) in the pipe.
