Excessive build-up in the disposer may require additional uses of Disposer Care®. One recommendation we make is to run a stream of hot water into the disposer for a couple more minutes before using Disposer Care® to break up the excessive waste. However, never use hot water alone as it may melt the build-up that may re-solidify in your pipes as it is flushed from the disposer.
You should never pour grease or other thick liquids down the drain because they can solidify and cause further blockage to you drains and pipes, in addition to causing a stench.
