Mold at water level in toilet

Susan Cryor
by Susan Cryor
I have done the white vinegar, 5 gallons in the tank after draining the tank and bowl. Cleaned the toilet completely on the outside. Used vinegar to treat the over flow holes in the sink. Even put some Down the shower drain. Mold grows over night where the water meets the toilet bowl, not a lot, just enough to make the toilet look dirty....certainly not like it did before the vinegar application/cleaning....any suggestions on how to get rid of this issue? It is bugging me, do not like dirty toilet.

    Have similar problem. Doesn't grow that quickly so I'm interested in your replies.

    Could you possibly have mold spoils in the water or air? If the water is in use during the day and not stagnate then something more serious might be going on. Be sure to use bleach. Could this maybe instead be some sort of sediment from the minerals in the water instead of mold?

    That would really make me question your water supply. Kinda scary. But yes, use bleach, (love that stuff). I would check in the back of your tank too, They have the little disks that you can drop into the back to help keep it clean.

    I would say use bleach. Don`t let it sit too long in your tank. After a bit flush it a few times.

    Clorex outdooors will do wonders. You can buy it in Home Depot or Lowes.

    Have 2 other bathrooms, one with out window ( downstairs hallway ) no any of them, and one is directly behind this one ( with wall between ) no, it is not in use during the day. It is a spare bedroom that I have been working on....unless I use it, but definitely no use in the evening. Koehler.toilet ..same as two others. One in hall bathroom is Gerber. It is mold. Not minerals or I would be fighting that issue everywhere. Highlander, I can not use bleach (lung issues n not spray can products either) I was told that bleach bleaches mold, vinegar kills mold not bleach.

      @Susan Cryor Not sure who told you bleach does not kill mold, it most definitely kills mold!

  • Susan Cryor Susan Cryor on Jan 03, 2014

    do you have city water or a well? Do you use a water softener?

  • Melissa Gutilla Melissa Gutilla on Jan 03, 2014
    it grows in my one bathroom also. It is used a couple timers a day. I dump bleach, white vinegar which ever is closer at the time. I have no idea why it is there either! Never happens in my other to bathroom!

  • Susan Cryor Susan Cryor on Jan 04, 2014
    we had mold specialist come....on mold in basement. I was told about bleach from them. They said white vinegar n hydrogen peroxide equal parts killed mold.

  • Susan Cryor Susan Cryor on Jan 04, 2014

      @Robin Miller Cresci via Debi Harper..your statement must be inaccurate. I keep bleach tabs in my toilet tank all the time; we have a septic stytem, rural. We have only pumped it ONCE in 32 yrs.!

  • Moxie Moxie on Jan 04, 2014
    I would then demise that the culprit is in the water only to that toilet or the air. Obviously as you have noted, there is something different in this bathroom from the other. Check to see (may not be easy to figure out) if there is a vent line coming off the sanitary line to this toilet...maybe something is in it. Same for the sanitary and water lines that spur off to this toilet...there is something different in the utilities to this toilet. Water in ok, water out growing mold. I know that is not an answer per say but since it keeps re-occurring, there must be a source.

  • Susan Cryor Susan Cryor on Jan 04, 2014
    good idea But know it is vented Plumber due here next week Will ask him Thanks

  • Kathy S Kathy S on Jan 04, 2014
    Try not keeping the lid down and see if that helps.

  • Debi Harper Debi Harper on Jan 04, 2014
    There is a Lysol bathroom cleaning spray I buy at the Dollar Tree, it works wonders for our bathroom and kitchen at the vacation home beside lake.

  • Sherrie Sherrie on Jan 04, 2014
    Keeping the lid down will create mold, I would whether clean the toilet more often then to see a lid left up. Mold needs a warm, moist place to grow.

  • Susan Cryor Susan Cryor on Jan 05, 2014
    two days and holding....all gone. Why would anyone put holes in the tank lid of a toilet ? I have always felt the overflows in sinks were a dirty place, and clean them regularly but now the tank lid as well!

  • What worked for you??

  • Barb Barb on Aug 08, 2015
    Zep has a good cleaner you might try. Also mixing one part hydrogen peroxide and two parts blue dawn dish washing liquid cleans everything beautifully. Hope one of these helps.Help answer this question...

  • Susan Cryor Susan Cryor on Sep 23, 2015
