Hi:
We have a Congoleum linoleum floor in our kitchen. Under our dogs' water dishes a yellow stain has formed where the moisture was trapped. We tried using Congoleum's recommendations of rubbing alcohol or a leaving a cloth soaked in bleach on the stain, but to no avail. Congoleum told us that if that didn't work, nothing will.
Does anybody have any recommendations for removing these yellow stains? Thank you for your time.
