Is there any way to remove yellow staining from vinyl bathroom floor?

by Mary
The staining was not due to spilling something. It appeared over time and since it is right along the outside of our shower I'm assuming it has something to do with moisture. Help would be appreciated. Thank you.

    I have this too , in front of the toilet! It is not due to pee,it is due ,in my case ,I think, to water stain from under where the toilet sits. Rust? We covered most of it with caulk,and a rug.

    however a vinyl floor I had in another house started showing yellow stain in spots from under the floor. Is it the glue that was used? Is it the particle board? I never found out. I am anxious to hear from readers about your stain too.

    Actually I have this same pattern vinyl in this bathroom. 😯

      Atiram4....what have you done with bathroom floor? Any solution yet? I recently read a couple of posts about painting the vinyl floor successfully. Being sure to put poly or something to seal it with after painting. Such a small floor...hmmmm such a little problem if it doesn't work.......🤔🤔🤔🤔

      I'll try on a small area and see how it works. Thank you.

    Had this show up on my vinyl floor near my kitchen door. Had the manufacturer's rep come to take a look (floor still under warranty). He said that moisture from the non insulated basement came up and caused mold. Not covered by warranty. I kept the floor for a few more years, then replaced it with 12" square vinyl tiles. No more sheet goods for me!

    Thank you. Our floor below the bath is also non-insulated.

    I had sheet vinyl in a prior home in both bathrooms and kitchen. The lighter colored floor showed the yellow stain around the perimeter within 2 years of installation. It was only glued down around the perimeter, and around the toilet. The darker floor (2nd bathroom ) showed no discoloration. Our basement was insulated and finished, so that wasn't the issue in that house. I talked to several flooring people (not the ones who did the work) and got different answers from each.

    1). Moisture getting under the vinyl and soaking the underlayment. The stain will be permanent as there is no way to raise the vinyl up to dry it. Best fix would be to replace flooring and fix whatever leak caused the problem. (Turned out to be the toilet after all. Wax ring failure. We ended up replacing the floor, underlayment and the toilets wax ring).

    2). Wrong adhesive was used to glue the floor down creating a chemical reaction between the glue and the underside of the sheet goods. No remedy that didn't involve replacing the flooring.

    3). The kitchen flooring was also a light color, but had no discoloration at the edges. This floor had been glued down thoroughly its full area, not just the perimeter. The only problem I had was if something heavy and sharp got dropped, it would nick the surface.

      I would go with the wrong adhesive answer. When we did vinyl tiles in our kitchen the guy at the store showed us which one to get as he told us the wrong one could show through the tiles and make them look dirty/old.

    Yellow staining does indicate moisture and/or hydrostatic pressure coming from your subfloor underneath the floorcovering. A common phenomenon that occurs therefore I would suggest using a ceramic /porcelain tile or a vinyl tile such as Armstrong's Alterna. You can install another vinyl sheet good over the existing, but you must float out the existing floor with a concrete patch product and let it fully dry. The eliminates the old floor embossing from photographing through the new floor. Good Luck!!!

    Thank you so much for taking the time to help me out. Your explanation was very easy to understand. Sounds like you've had experience with flooring. Greatly appreciate your help!

  • Mary Mary on Mar 22, 2017

    Susan- Thank you so much for taking the time to send me your comments. Looks like I will eventually have to get new floor or learn to live with the yellow staining(ugh).

    If you previously had tile/linoleum down, and then took it up, you are supposed to scrape the black glue from the subfloor before putting down new sheet goods or tile pieces. These glues can migrate into new goods. Float a concrete patch over all the floor, level really well, let dry, then proceed with new goods. By the way, this is a good time to remove any nails in the subfloor and replace them with screws. This prevents nail heads from migrating up through the new floor at a later time.

    Proper installation of vinyl sheeting is always do whole floor. Check around toilets b4 laying down, and installer needs to use right glue. I'd be on them like white on rice with questions b4 they put it down.

    Thank you, Linda!

    I have a yellow stain from where I stand in front of the kitchen sink. Figured it was from the rubber in my tennis shoes. Don't have it anywhere else.

  • Mary Mary on Mar 25, 2017

    Thank you, Marilyn.

    Had that problem around edge of shower, used a Mr Clean Eraser. Worked great.

    I don't think this is a glue issue( else it would show in other areas),I'm thinking moisture has gotten under the flooring. I see several culprits in the photo. 1. The quarter round looks like it has a small gap between it and the floor, which will allow water to get under it. 2. Is there caulk along the edge of vinyl at the shower( I couldn't enlarge photo to see clearly) if not that is a definite problem. If this is a moisture issue there is no cure for the stain except replacement. As stated previously, if you replace the floor, make sure there are no leaks in the shower pan itself. Even a small pin hole can be disastrous over time. Then have the old floor skim coated with a concrete based patching compound (it could take 1-3 coats depending on the depth of the embossing lines) and allow to dry completely between coats. When new floor is installed, I would use a bead of caulk behind the quarter round before placing it back( this will stop moisture) and run a tiny bead at the bottom of quarter round after it has been installed and definitely run a bead in front of shower. I have been a flooring installer for 23 years and anything I can do to stop moisture from getting under the flooring in high water areas I do.

    Thank you, Ron, for taking the time to give me such a thorough explanation. Wish you lived in my area since I will be looking for someone to replace floor. It's hard to get experienced people. Much appreciation!

    Thank you, Patricia!

  • Try Magic Eraser.

    Hi Mary, hope this helps you out.

    For yellowing vinyl, a solution of bleach and water can work wonders. Mix three parts of water and one part of bleach in a bucket and use it for rubbing the stained areas. The stains may not completely get removed in the first attempt.

  • Johnavallance82 Johnavallance82 on Aug 16, 2023

    Do you have a mat normally out side shower, as yellowing could be caused by rubber sweating! Try Barkeepers friend.

  • Redcatcec Redcatcec on Aug 16, 2023

    Use a Magic Eraser to remove the stain.
