A bit of routine maintenance will keep you from washing money down the drain
Your garbage disposal will lock up on your just when you need it most say, at Thanksgiving dinner. To keep things flowing smoothly follow these handy tips:
Run cold water when you are putting food down the disposal, while the disposal is on and for 15 seconds after you hear that the disposal has finished grinding everything up. Generally, you only need to run the water for about 5 seconds after grinding, but the potential for a clogging buildup is heightened when the disposal is turned off right away with no additional clean water run through it.
Every so often, put ice cubes into the disposal when it is running with lots of water flow (the more ice the better) to keep it from developing internal buildup and clear out any smell without using toxic chemicals. Dropping some lemon or orange peel wont prevent clogs but it will make your disposal smell pleasant.
Try using several gallons of boiling water down the drain to help clear grease build up farther down the line in the machine, followed by another 20 seconds of running cold/warm water through.
Your garbage disposal can benefit from a product called Glisten that can help remove the crud in the main chamber if the ice cubes and boiling water and changes in usage do not completely clear the occasional back flow of water up into the sink.
