Can you use anything else instead of water for Baptism?

Hello.

The Greek Word for baptism is ba'pti.sma refers to the process of immersion, including submersion and emergence; it is derived from the verb , " ba'pto, meaning dip. In The Bible, "to baptize" is the same as " to immerse."

The baptism of Jesus hinself as performed by John was his immersion in the Jordan, and was approved by Jesus' Father Jehovah. Read Matthew 3: 13-17.

So to answer your question, it is difficult to immerse someone in anything else than water. The meaning of immerse is "putting the whole body under water", according to the Oxford Distionnary.

Kind regards
