Some Possible Reasons For Discolored Grout Around Toilet

If you want to know why toilet grout looks dark, brown, or yellowish then I’ve listed some strong reasons behind the discoloring of your toilet grout:

Reason 1: Hard Water Supply

If there is a hard water supply through the pipeline in your area then your toilet grout can easily get a brown stain with time. According to the USGS report, nearly 85% of USA homes got a hard water supply. 

Reason 2: Soap Scum

Soap scum contains fatty acids that react with minerals present in the water and discolor grout around the toilet or your bathroom tiles. You have to immediately take the necessary steps to clean it. 

Reason 3: Oil And Grease

Oil and grease particles stick to the surface of your toilet grout and tiles and attract dust and grime. In most cases, oil and grease make white grout dark. If you don’t take proper attention to them, it becomes hard to clean them. 

Reason 4: Grime

There are many reasons grout becomes dark and grimy such as dirt, mildew, etc. The grout is slightly below the surface of the tiles which makes it difficult to clean.

Reason 5: Improper Cleaning 

This is the main reason behind the discoloring of grout. Most of us keep our attention on cleaning the tiles but forget about grout. Not Giving importance to the cleaning of grout is also a big reason for discoloring grout.

Natural Ways To Make Dull And Discolored Grout Around Your Toilet Look Like New And Fresh 

In this section, I will share some natural and safe ways to keep toilet grout new and fresh, if it turns dull, yellowish, or brown with time. 

Method 1: Make Your Toilet Grout Whiten If It Becomes Brownish

If you notice the color of the grout turns brownish from white, it means your home has a hard water supply. Manganese and iron components make grout color brown and rusty from white. 

Follow these steps to make grout again white from brown or rust color:

Step 1: Use Vinegar

If your bathroom has synthetic or ceramic tiles then you can use vinegar to clean it. 

  • First, wear hand gloves and safety glasses before starting the process.
  • Take a spray bottle and fill it with white vinegar. Don’t add anything else to it. 
  • Now spray gently over the surface of the grout around the toilet and leave the surface for 5 to 10 minutes. At this time vinegar penetrates the grout and makes the cleaning process easy. 
  • Now wear a silicon scrub hand glove or use a brush to rub the grout surface. 
  • Now clean the surface using a dump cloth.
  • Now Mop the surface for thorough cleaning.

Note: Don’t use vinegar on marble, travertine, or limestone because it will damage the grout and its sealant and you will end up with a costly repair process.
