ZEROREZ® uses a product called “Primacide B fluid”. This product is either made by EAU and shipped to ZEROREZ® or ZEROREZ® has purchased the generators necessary to manufacture this fluid. EAU Technologies (the creator of empowered water™) describes this fluid as “the active ingredient in Primacide B is sodium hydroxide”* and that it “leaves no film residue associated with chemical detergents”*. Sodium hydroxide, also known as Lye is found in many drain cleaners and oven cleaners, it is highly corrosive (in high concentrations) and will eventually turn into sodium carbonate when exposed to carbon dioxide in the air.
What we know so far:
- ZEROREZ® uses a fluid that contains a man-made chemical that is corrosive at high concentrations and is also used in drain cleaners and oven cleaners.
- ZEROREZ® claims to leave zero residues behind when EAU claims that “Primacide B Fluid” leaves “no FILM RESIDUE associated with CHEMICAL DETERGENTS“.
What else we have learned:
- ZEROREZ® still claims to be residue free.
- Surfactants seem to be a very important part of the cleaning process.
- It seems ZEROREZ® uses chemically infused water without surfactants.
- Company B and ZEROREZ® both use hot water extraction, the method recommended by most carpet manufacturers.
Let’s dig deeper. We now can assume that ZEROREZ® uses chemically infused water. Knowing this, how can they claim to be residue free? It is well-known among the carpet cleaning industry that when you apply a solution to the carpet, you can’t fully extract 100% of what you put down. Both ZEROREZ® and Company B are applying solutions containing either man-made or natural chemicals to the carpet and both use Hot water extraction to remove said solutions. The difference is ZEROREZ® seems to be leaving a man-made chemical residue that eventually turns to sodium carbonate (or sodium chloride, depending on whether hydrochloric acid is used to neutralize the sodium hydroxide) and Company B is leaving a similar but naturally sourced residue along with a surfactant residue in the carpet. The question is – Which is worse? Or maybe the question should be – Who is more experienced, and who works harder to rinse out as much residue as possible? Both of these methods offer VERY low residue cleaning when properly done.
Hot water extraction has gotten a bad rap over the years because of the many inexperienced and unscrupulous cleaners out there that are more concerned about making a buck than providing a quality service for their customers. In my opinion, hot water extraction, when done by an experienced and honest company is still the best method out there whether done by ZEROREZ® or by small, Ma’ and Pa’ shop down the block.
