There is a burgundy “substance” on old concrete floors under carpet pad. I tried to see if I could clean it up (in different areas) using
All that happens is it turns in to a burgundy mess painting the cement burgundy with each wipe … essentially making the problem worse. Scrubbing same spot repeatedly is showing some slow minor improvement but seems impossible I could clean the entire floor this way .. it could take weeks.
Any idea what this burgundy may be? (It may be mold but it doesn’t smell)
Anyone ever seen similar in their basement?
