It is a positive commandment to remove the ashes from the altar each day, as [Leviticus 6:3] states: "And he shall remove the ashes." This is one of the services performed by the priests.
The priestly garments [worn] when removing the ashes should be less valuable than those [worn] when performing the other aspects of Temple service, as [ibid.] continues: "He shall remove his garments and put on other garments and remove the ashes." The term "other" does not imply ordinary garments, but rather [priestly garments] that are less valuable than the first. [The rationale is that] it is not proper conduct to serve a cup [of wine] to one's master in the same clothes as one cooked food for him.

Any one of the priests who desired would collect the ashes that were brought down [from the altar] and take them outside the city to the ash depository. Taking the ashes outside [the Temple Mount] did not require a lottery. Instead, whoever desired [was allowed to do so]. None of the priests were ever lethargic about removing the ashes.

Although removing [the ashes] outside [the Temple Mount] is not considered as service, it should not be performed by priests with disqualifying physical blemishes.
When it is removed outside the city, it is deposited in a place where the wind will not blow it powerfully, nor [rivers] would not flow into it. It should not be scattered there, as [Leviticus 6:3] states: "And you shall deposit it." [Implied is] that it should be placed down gently. It is forbidden to benefit from it.

The priest shall dress in linen raiment, with linen breeches next to his body; and he shall take up the ashes to which the fire has reduced the burnt offering on the altar and place them beside the altar.

He shall then take off his vestments and put on other vestments, and carry the ashes outside the camp to a pure place.
