Prevent roaches,eliminates smell from your car too.

Last time during my "waja" days.I spilled a whole cup of coffee onto the seat.Since it a fabric material and the coffee already absorb to the seat i could not do anything.The smell was terrible after the coffee had dried.Someone told me put pandan leaves.After 3 days the smell was gone like magic!
