After 13 years of soaping my main sewer line is plugged and the plumber is on his way!!!

After 13 years of soaping my main sewer line is plugged and plumber is here! I'm positive it's due to my washing out my pot and utensils after making a batch in order to make another batch, rather than waiting until the next day Wondering if anyone else has experienced this situation too? If so, any suggestions?

Get more pots and utensils so you don't have to wash fresh, oily soap batter down the drain.
Wipe out the bowls much as possible and wait a day or 2 for the remaining batter to saponify
