It is best to allow the solids to decompose before emptying your toilet. The longer you wait before emptying your toilet, the nicer the job will be.

Many boaters will leave the solid wastes in the toilet over the winter and empty it in the spring. That may not be possible for some applications, but you will find that even in as little as one week much of the solid wastes have begun to decompose, and just the paper products are visible.

It is best if you do not leave the liquid wastes in the tank for extended periods. While everyone is different, some urine will smell bad if allowed to sit for extended periods.
