As mentioned in the previous days, the primary concern of chameitz lying around one’s home is because one may eat the chameitz food. This obviously is not a concern when it comes to crumbs. Therefore, there is no need to drive oneself crazy to find every crumb in one’s home. If one does not have young children and there is no concern about food being hidden in all sorts of places then one should not be breaking a sweat when cleaning for chameitz.
However, when it comes to the kitchen there is an additional concern of eating chameitz. It is forbidden to eat even a drop of chameitz. That being the case, if a crumb of chameitz is left on one’s kitchen floor and a piece of food falls onto the floor on Pesach, the chameitz can get attached to the food and become forbidden to eat. Therefore it is imperative to meticulously clean one’s kitchen.
In addition, anything that came into contact of hot chameitz during the year retains a chameitz status and if it comes into contact with hot food on Pesach can make the food chameitz and forbidden to be eaten on Pesach. We therefore must purge all appliances and surfaces before Pesach to remove any chameitz from within them. The laws of purging appliances, otherwise known as kashering, will be discussed in the coming days.
