The Proof: It is Possible to Disinfect Laundry With Cold Water and Less Detergent

Professional laundries use hot water and detergent because it's the only way to get clothes clean and rid them of potentially harmful bacteria. But is that entirely true? Is it possible to wash clothes in ambient water and get them completely bacteria-free?

Part of the promise of using the Hydrofinity laundry machine is it lowers the need for hot water and detergent - reducing a commercial laundries water use by up to 80%, energy use by 50% and detergents by 50%. We've known using our system is effective and delivers a superior wash but, scientist that we are, we wanted conclusive scientific proof that Hydrofinity gets clothes as clean and bacteria-free as conventional washing.

The Study and the Proof

To perform our study, we added five types of bacteria commonly encountered in dirty laundry washloads to several cotton cloths. For the record these bacteria strains were:

  • Staphylococcus Aureus (source: Respiratory tract, skin)
  • Pseudomonas. Aeruginosa (source: Soil)
  • E.Coli (source: Fecal matter)
  • Enterococcus Hirae (source: Fecal matter)
  • Klebsiella Pneumoniae (source: Fecal matter)

Each bacteria was added in equal amounts to a separate cloth. For purposes of testing, we went heavy on the amount of bacteria added. This was no ordinary washload, this was a very infected one and in immediate need of cleaning.

We then washed these infected pieces of fabric in separate groups - one batch was washed in a Hydrofinity washing machine and the other in a conventional aqueous machine. The crucial differences between the two machines was the reduced temperature, reduced water and reduced detergent used in the Hydrofinity machine, made possible by our patented technology.

In contrast to the industry standard hot water wash temperature of 149 degree Fahrenheit, Hydrofinity machines run at a temperature of 68 degrees. But in order to fully explore the issue we tested in a variety of differing conditions - Hydrofinity machines running at 104 degrees and 149 degrees with varying additions of cleaning agents. We also tested bacteria-infected cloths using different cleaning agents in the conventional washer. 

After washing, the cloths were set aside in ideal bacteria growing conditions for 1-3 days. At the end of this period, the number of bacteria present were counted to see how many had grown back. Our findings indicated the disinfecting efficiency of a Hydrofinity washer using lower temperature water effectively killed bacteria at a 99.9999% rate for 4 bacteria types and at a 99.99% rate for Pseudomonas Aeruginosa. This rate was comparable to conventional hot water washing.

This scientific proof is just further validation for our statement that Hydrofinity represents the first revolutionary progress in clothes washing technology in over 60 years. Click here to learn more about how our machines work.
