Is Wudu' invalidated by using soap and a sponge?

A: What invalidates Wudu' is touching the front or back passage (urethra or anus) with naked hands. However, touching them with a barrier does not invalidate Wudu'. Thus, if you were in a state of ritual purity before having your bath, and you did not touch your private parts with your naked hands, or touched them with a barrier, and nothing came out from the urethra or anus, your Wudu' would not be invalidated.
