To be fair each time I change scents of fluid I change over to a new smoke wick and clean the resovouir good before adding a new smoke fluid so I'll get 100% of the true scent. You can make your own scented fluids using food grade mineral oil from the drugstore and candle scent oil. Anyone who doesn't care about the scent and just wants plumms of smoke can use rc airplane smoke oil like Robarts liquid sky that can be had for 20.00 a gallon.
