Sponge on Shabbat

Hi Rabbi- on shabbat if i want to wash netila and there is a sponge in the sink: 1. can i take the sponge out of the sink, or is it mukse? 2. can i wash as normal with the sponge in the sink if it for sure will get wet?

M.b. allows to remove the sponge but since its כלי שמלאכתו לאיסור you can only move it if you need the space
