Grout Cleaning Service Auckland Wide
This video contains two main lessons. First of all, the results of grout cleaning solely depend on the “quality” of dirt, NOT the quality of cleaning. Whenever some stains can survive our chemicals and machinery, they are there to stay. Old solid stains make the perfect background for a grout colourant coat. It would be a problem only if the stain was fat-based. How do we know it’s not? The fat is the first to go (zero chances of surviving the cleaning process).
Secondly, because cleaning brings unpredictable results, we cannot guarantee uniformity of old grout colour without using grout colourant. Cleaning jobs are accepted based on one principle: take them as they are. The basic machine-cleaning process can make a significant difference, but stains may still linger. Cleaning stains can be more expensive than replacing a tile (it depends on the stain and the type of tile).
Please, have a look at the results of machine-cleaning of grout.
The only way to achieve this level of cleanliness is through the use of proper dirt extraction equipment. SCRUBBING BRUSHES CANNOT CLEAN POROUS MATERIALS. Regardless of how funny it looks, heavy equipment is absolutely necessary for any size job. It’s not about cleaning, but mainly about rinsing. Leaving stubborn stains behind will not affect the adhesion of grout colourant. However, the dissolved dirt and chemicals left behind reduce the lifetime of sealer coats by 80%.
The grout needs to be chemically neutral before sealing. The rinsing of a shower is no big deal, but what about a tiled kitchen or dining floor with tiles tacked to carpet? I can pour a bathtub of water under pressure without getting a drop on the carpet. That’s what sets me apart from the vast majority of so called grout restorers. I would like to emphasize this message once more. I am a TILER, not “a grout restorer”. As far as my memories go, “the grout restoration” was known as tile maintenance and it was performed by the tilers.
The grout preparation is more about proper rinsing than cleaning !
Leaving stubborn stains behind will not affect the adhesion of grout colourant. Leaving dissolved dirt and chemicals behind will shorten the sealer coat’s lifespan by 80%. A sealer can only be applied to grout that is chemically neutral. While rinsing a shower is not an issue, what about tiled floors in the kitchen or dining room that are attached to carpets? I can pour a bathtub of water under pressure without getting a drop of water on the carpet. This is what sets me apart from the vast majority of so-called grout restorers.
Steam cleaning follows similar rules. The difference between domestic and commercial steamers is enormous. Domestic steamers release steam once the water reaches boiling point (not much pressure). My steamer (Jetsteam Maxi) works at a temperature of 175°. You should keep in mind that grout pores are microscopic. Only pressure can remove dirt from grout pores (by pushing it out of the pores and bringing it to the surface, so it can be removed).
