Or maybe there is a better product, that's commonly available at Home
Depot or Lowes or etc?

Thank you Lee Carkenord

A snake. Chemicals (corrosives) may help, may even clear it, but a snake
removes the clog. You may want to open the trap and check it out to see if
the clog is just a big hairball that you can pull out. I've take short cut,
but nothing works better than a mechanical cleaning in the long run.
