Besides consuming it, are there other ways to use Sai Baba's Udi mentioned in the texts?

Chapter 33 of the Shri Sai Satcharita describes multiple ways to use the sacred Udi. The most common method mentioned is to apply it to the forehead after face-washing and bathing. Another powerful method is to consume it, often by mixing it with Charanteerth (holy water from feet) for purification. The text also highlights another practice where a devotee created a Tait, which is an amulet, from a bundle that miraculously contained Udi. This amulet was then tied with great reverence to the wrist. This suggests that keeping the Udi on one's person in a sacred container like an amulet is also a valid and powerful way to receive its continuous blessings and protection.
