    Dunno, could be melt (from heat), could be tar, could be mold, could be grease, could be subfloor rot or even Pam Spray...hard to say really without a process of elimination.


    For Tar, Grease or Pam Spray:

    Try soaking it in a puddle of vinegar and then apply wax paper over it, and Press it with an iron.

    Usually when you peel up the wax paper that will pull up any hot tar or goo.


    If it is not those but gets worst with heat it is Melt rather than Mold.

    Otherwise it is most likely mold or rot that is spread even worst underneath the Linoleum and discoloration occurs from underneath as rotting is in that section.

    Granted, you can cut out a Circular or Square Section to create a Multicolored Floor effect, but that is alot more work than grabbing an extra tile out of a closet to replace a 1 square foot damaged tile.

    When that is so, you realize you maybe should have went with Tile rather than Sheet, because: it very hard to Match a Sheet Linoleum that has Discontinued, unless you have some extra in a basement or attic.

    Sheet Mold needs replacing at least a Section, at times even the flooring entire, cleaning up the mold, and using a better mold resistant subflooring for your new floor.

    It's hard to tell from the pics, but it sure looks like rust or grime.


    What have you tried to clean them?


    If I were in your shoes, I'd give Bar Keeper's Friend a try. It's commonly available at the store near the other cleansers and won't damage the finish on the linoleum.

    How old is the flooring? Could it be that the discoloured section is due to sunlight continually being reflected off a portion of the glass in the door, almost 'burning' off the top coat of the flooring, over the years?

    I would try sprinkling some baking soda, a squirt of dish soap, and a little vinegar. Let sit for awhile to do its work, then use a scratcher pad to get the rest up.

    If you have a wood substrate (Crawl space or second story) underneath the sheet goods, it could be "moisture" wicking up from underneath the subfloor. Not a lot you can do about it, but if you do choose to replace...........leave the old floor down as a moisture barrier. Then, skim coat the old floor with a concrete patch product (Ardex) to erase the old pattern so it doesn't photograph through the new floor. Make sure the patch fully dries before installing a new floor on top. May I suggest glued down vinyl planks........looks great and easy to repair one small area in lieu of replacing the entire floor. Looks great too and maintenance friendly!!!

    Without being able to look at it close up I would try putting some lemon essential oil on it. Leave it set 5 -10 minutes and scrub off. This has worked for me on various floor and counter stains very well.

    I have had linoleum with a similar stain. Once it was mildew and I had to replace the flooring. Another time the installer used the wrong glue. I actually painted over my entire lino floor with wall paint and several coats of urethane which lasted for years. Neither one would just scrub off. I would try soaking the spot with baking soda and a bit of water to create a paste, after about 15 minutes add a few table spoons of white vinegar and let it bubble. Then try scrubbing with a Mr. Clean Magic eraser. If that or bleach doesn’t remove it, you might have one of the issues I mentioned above. Good luck🤗

    I'm wondering if you have water seeping in under the linoleum because of that door. That could easily set off some type of mold growth.
