As any homecare enthusiast will undoubtedly know, ensuring grout is well-cleaned is essential if you want a sparkling bathroom and kitchen. Given that grout is a porous substance, nasty mould and mildew may well end up thriving if you don't keep on top of it, resulting in unsightly stains.
One first-time homeowner was recently dismayed to see the grout in her new home was "stained yellow from smokers", and decided to take action using a product she now swears by.
Taking to the Mrs Hinch Cleaning Tips and Tricks Facebook page, a page where lovers of online cleaning sensation Sophie Hinchliffe share their own advice, the woman, whose name is Steff, recommended others follow suit, showing how she was able to get her grout gleaming once more.

Sharing before and after pics on the group, Steff explained: "We have recently bought our first home and we are in the process of renovating it.
"We plan on renovating the whole bathroom late next year but for now, I still wanted it to look nice in the meantime without spending a fortune. The grout was stained yellow from smokers. I cleaned the area before applying the product."
She continued: "I've tried grout pens in the past and find them not so great as they wash off after a while. Found some grout reviver paste on Amazon and it's the best way to remove the marks.
"You squeeze it on, leave it for three to four hours, then wipe the residue off without the need to scrub. The results speak for themselves. Super pleased and only cost £3.50 to do. It has an anti-mould barrier built in too, so it even prevents mould growth while removing tough stains."
The "amazing" and "super cheap" product Steff used to spruce up her grout is called Everbuild Forever White Grout Reviver, described on the company website as being "the easy way to restore discoloured and dirty grout to a bright white finish".
A number of Steff's fellow group members have also praised the product, with one person writing: "I've had good luck cleaning gross grout in this 72-year-old home we moved into three years ago using this product."
Another commented: "Since I saw the way this paste revived your grout I have to try it out myself as my shower grout had turned black from dirt and mould.
"It was so easy to use and gave me such great results. I only had to use half a tube of the stuff. I've previously used bleach, but this is so much better."
