What are the Pink/orange stains on tile grout, sink drain, shower curtains?

I get this build up of pink/orange staining on all white bathroom fixtures. It comes off with a lot of scrubbing, but I can't figure out what it is. I have city water, not well water. I have heard some people say it's from fluoride and others say its from bacteria. Anyone know for sure?

Actually the answer has NOTHING to do with soap scum or any other debris.


The answer is from a bacteria.


I've provided in this pdf. to help you understand the situation.

this is the best answer that is also reliable.





note: you can make a more effective and cost effective cleaner than "Tilex" or any of the other products by mixing 15% bleach with water and use a new spray bottle that you clearly mark with the content.





If you ever want to know exactly what is contained in the products you use for cleaning and also want to compare which have the greater percentage of active ingredients,


then here is the link to the National Institutes of Health's Database:

You'll never have to rely on someone's opinion and anecdotal evidence again.
Reply:Well unfortunately you asked so I will tell you . that is a combination of skin tissue and soap and hard water residue..


I own my own cleaning business and the only way to keep it clean is scrubbing..First, remove your shower curtain and wash with a white sheet, use 1 cup of vinegar,no soap..then rewash with soap and one cup bleach. This should remove all the residue and mold. Now for the bathroom..Use the brand called Softscrub with bleach...Not the spray on kind...scrub and rinse well..Make sure you get all the residue from the cleaner off..now use a product called Tilex Shower Shine.. Use it right after u rinse the walls clean...also use this after u shower, on the walls and the shower curtain..this way you only have to clean it every two weeks..
Reply:I'm in agreeance with the other answers that it is pink mould. A new cleaning tip I learned recently that works wonders is to dry the shower, sink etc then sprinkle with bi-carb soda and pour on some white vinegar. The bi-carb will froth up and you scrub while it is frothing. This combo lifts the mould and soap scum etc really easily. White vinegar is a must for cleaning the bathroom and bi-carb is a great deoderiser. A small tub of bi-carb in the bathroom will help soak up the moisture from the steam when you shower too!
Reply:Sounds like it's pink mold, which develops pretty quickly in bathrooms or any areas that stay wet for long periods of time. Cleaning regularly is the only solution I'm aware of to tackle it.





It could possibly be something else, but that's the only thing I'm aware of that has that colour and develops in bathrooms.





I found a link, listed below. From a few quick searches, it seems that mold and mildew are almost interchangeable terms, though some sites suggested that mildew is only brown/grey while mold is also pink and a variety of other colours. Either way they're similar entities, and handled the same way - with proper lighting, ventilation, trying to keep things dry, and regular scrubbing.
