Cleaning certain areas of the bathroom can be tedious, especially when it comes to stained grout.

Grout is an essential part of any bathroom, as it fills in the spaces between tiles.

Due to its porous nature, it can be a hotspot for germs, bacteria, mould and mildew to grow.

Many people don’t even notice that their grout is getting dirty until it discolours, turning a red or dark brown colour.

For those who just can’t seem to get their grout clean with vinegar and baking soda but don’t want to go through the hassle of rerouting, there is another option.

“It offers a simple application process without the need for specialised skills or tools. It enhances the overall appearance of tiles and provides a protective barrier against future stains and discolouration by restoring the original colour of the grout with long-standing results.”

How to use a grout pen 

Before you begin, cleaning your grout lines thoroughly is a “crucial first step”. Scrub the grout with a brush, or old toothbrush, to ensure it's as clean as possible, then wipe over the tiles with a cloth to allow it to dry completely.

Before using a grout pen, make sure to shake it well to allow the ink to be evenly mixed, pressing it on a paper towel a couple of times until the ink begins to flow. 

Ryan noted that the pen’s fine tip is “designed for precise application”, so you’ll have control over where the ink goes and can avoid getting it on your tiles. For the best results, apply a consistent amount of pressure and move steadily along the grout.

Let the ink dry fully before touching or cleaning the area, which will usually take about four hours, avoiding contact with water too during this time. 

The grout pen’s ink is designed to be “long-lasting and resistant to stains”, so you’ll enjoy a clean, refreshed look for “months to come”. 

It also acts as a grout sealer, helping to prevent future moisture, and “protecting against mould”.
