Biological Treatment

The Biological Treatment provides your washrooms with a revolutionary new solution to keeping them sparkling clean and safe with minimal effort.

Your washrooms have had hygiene issues for years. From grimy urinals or nasty odours, these problems just seem to be inevitable.

Your solution? To use toxic, nasty chemicals to try to fix things.

Not only does this not work, your staff and customers end up suffering, and your business’s reputation is impacted negatively.

Alsco has the solution – quite literally. It’s preventative. It’s powerful. It’s also environmentally-friendly. The new ‘Biological Treatment’ is precisely that.

Using biological methods never used before in New Zealand, this doesn’t just clean your washrooms. It prevents them from happening in the first place, leaving you to focus on what you do best – your business.

Key Features

  • A thorough, deep clean removes all dirt and bacteria
  • Unique, healthy bio-soaps and natural ‘bugs’ eliminate nasty microbes, dirt and odours
  • Positive effects can be seen within 24 hours
  • Regular, quarterly servicing keeps bio solutions/blocks restocked and effective
  • Keeps traps and pipes unblocked and hygienic – saving you on cleaning, water and repair bills

Fresh & Clean’s biological solution literally eats dirt and dangerous bacteria in your washrooms – keeping them regularly clean, getting rid of blockages, and removing even the most tenacious uric acid build-up.

Where toxic, nasty chemicals are a costly, one-time clean, our biological solution is permanent. And as part of Alsco’s managed rental service, our experts will regularly clean, maintain and replace biological solutions and blocks, keeping your washrooms sparkling clean and problem-free indefinitely.

“…exceptionally good supplier of laundry, flooring, ablution supplies”

Lynne Lusty, HR Compliance Manager, TRT, Hamilton


The rapport and comradery between Alsco and TRT staff involved in service delivery was of a superior level. TRT has since handed over all ablution supply orders to Alsco. TRT has upgrade flooring in all departments and supports the initiative of Health and Safety messages on mats. The business relationship has also seen a three year agreement signed and an upgrade of lockers and cabinets in each of our 4 locations.

I think the most important aspect of the relationship TRT has with Alsco is the very short response time with any communication or issue and this truly does confirm the professional culture within their organisation.
