No. Is there a home remedy I can use to get out the stain in my white shirt?
user
Sorry, no.  Could you describe the stain, and your current approach to removing it?

It is a wine stain. I heard that baking soda can help.

The best tool for removing a stain would be bleach.  Baking soda is helpful when it comes to certain chemical compounds, but this seems like a different kind of stain.
