Discolorations in your tile and grout aren’t just unsightly—sometimes they are downright dangerous.
The dark spots on grout are most likely the result of mold, mildew or plain old dirt buildup. It is important to determine what you’re dealing with first, so you can wipe it out with the appropriate treatment plan. The only way to tell for sure is to ask a mold professional to collect samples and test it.
If you have had water damage or a long-term leak, what you see might be black mold: Stachybotrys chartarum. This highly toxic mold should only be removed by a professional. But, more commonly, your tile grout has a generic mold.
Mold vs. Mildew Guide
How to Treat Mold or Mildew
A major difference between mold and mildew is how to treat them. Mildew can be removed with standard household cleaning products and a scrub brush. Removing mold is more complicated.
Once a fungus has been tested and established as what kind of mold it is, the procedure for removing it will vary depending on the mold type. Some types of mold can be removed with specialized cleaning products and protective gear like a mask and goggles. Others, namely black mold, require hiring a mold removal professional like Commercial Cleaning and Restoration.
Mildew symptoms can include:
- Mild respiratory problems
- Sore throats
- Nervous system – headaches, memory loss, mood changes, depression.
- Skin and eye irritation
- Nasal and sinus congestion or dry, hacking cough
- Respiratory problems – wheezing, asthma attacks, etc.
- Aches and pains
