I was recently called down to Alderton, a small village in the southern part of Northamptonshire most famous for housing the remains of a Norman Castle, known as ‘The Mount’. Unfortunately, this job involved remedying a bit of DIY grout cleaning that had not gone as expected.
As the first photo shows, my client had attempted to use a well-known household cleaning product to remove stains from the grout of his bathroom tiled floor which had not been sealed. Grouts are porous and, as a result, they can easily absorb grease and dirt, so it is understandable that my client would have wanted to try and clean them.
Attempting to clean the stained grout
So what could be done to remedy the situation? My first action was to clean the grout using professional methods and products in an attempt to reverse the damage.
I did this using Tile Doctor 6″ twister pads, along with a hand-held buffing machine. The cleaning product I chose to use was Tile Doctor Grout Clean Up, which is designed to penetrate beneath the surface of the grout to lift out stains, smears and grout haze.
Recolouring the grout lines
I recoloured the grout lines using a white Tile Doctor Grout Colourant. This product is a waterborne epoxy that not only recolours, but also seals the grout lines in order to protect against further stains in the future.
