When working with liquids in the kitchen, sometimes it can be very difficult to be accurate when pouring. Funnels work wonders on turning inaccurate pouring into an exact science. They are good for pouring liquids from pots and pans into smaller bottles or jars. When purchasing funnels, one can choose between plastic or stainless steel funnels and the difference are somewhat vast. While they both do the same task, plastic funnels are much more economical and more dishwasher safe than their stainless steel counterpart. Plastic funnels cost much less and are easy to maintain, however they are not as long lasting as stainless steel and will need to be replaced on a somewhat regular basis. Plastic can also hold on to stronger odors much more easily that stainless. Stainless steel is resistant to rust and corrosion as well as smells and stains. The metal alloy is much more durable that plastic and will last much longer if properly cared for. The metal can be run through the dishwasher, but over time this will cause damage to the stainless finish and it is will begin to rust. A better option is to hand wash the funnel as much as possible and only use the dishwasher when absolutely necessary.
