A method is provided of cleaning trocars or cannulas and a lens of a scope by using a minimally invasive device including a rod having at least one sponge attached to an end thereof. The method includes inserting one end of the device through a trocar such that the at least one sponge is in contact with an inner surface of the trocar to thereby clean the inner surface of the trocar. The device is extended through the trocar such that the sponge is positioned within a body cavity. The sponge is used to clean the lens of the scope while the scope and the sponge are within the body cavity.
