Presco Environmental uses an ‘intelligent’ approach to cleaning, involving identifying the type of soil to be dealt with and then using the most appropriate cleaning chemical and cleaning process to remove it.

This service will help you if you …

  • are unsure how to remove soil from a surface
  • need to clean an are without mechanical action (areas where high
  • pressure will push water where it shouldn’t be, or flake paint)
  • cannot use abrasive cleaning methods
  • wish to save hot water, therefore save money
  • have a problem with biofilms, bacteria, yeasts, mold or viruses.


Presco Environmental technician cleaning with Enviroclean chemical


The solution to your problems

An intelligent approach to cleaning: identify the soil type, pick the most appropriate chemical and method, remove the soil.  Our technicians are all trained in chemical handling, and very experienced at picking the best solution for you – often after testing.  We really want to find the most effective, least harmful chemical for you.   Our first chemical choice will always be environmentally-friendly and food safety approved.  

Here’s a little trick we use to get the most efficient clean: increase one of the following TACT factors:
T = Temperature. Usually refers to using hot water. (Can include cold – google Dry Ice Blasting)
A = Action. Mechanical or manual cleaning actions (scrub, scrape, pressure wash)
C = Chemical. An appropriate chemical to soften and move the target soil.
T = Time. Covers both dwell time for chemical and time allowed for the cleaning task in general


What more can we help you with?

Aside from the actual chemical cleaning, we can help you with vacuum recovery of cleaning discharge to prevent entry into water ways.

We are certified approved handlers for HASNO (Hazardous Substances and New Organisms) and Agricultural Chemical handler (Herbicides, Insecticides,Fungicides), meaning we are competent in handling all types of hazardous substances


What are you alternatives?

  • You could use chemical-free cleaning.
    Wet or dry steam is good for oily or waxy surfaces.  Be aware steam cleaning usually requires 3-phase power.
    Dry ice blasting is excellent for removing baked-on soil and cleaning sensitive or difficult-to-clean components.  Dry ice blasting requires a high-pressure air supply.
    Pressure washing is a great affordable option if your soil is easy to remove, and water is not an issue.  The area needs to be able to drain.  
  • You could use abrasive blasting.
    This could be sand, soda or bead blasting.  This option cleans very effectively.  It removes everything, including paint and rust, and cleans back to bare metal.  It is not a good option if you don’t want to  create a lot of mess or have sensitive equipment – it is very harsh on seals, wiring etc.

Are you chemicals harmful to people, animals or fish?
We are talking about chemicals here – not usually things you want to bathe in or drink.  However, we always use the least harmful chemical at a dilution rate that is safe, and put the controls in place to protect people, animals and fish.  

Can you chemicals be put down the drain into the storm water or streams?
As in the answer above, we put controls in place so our chemicals do not cause any harm to storm water or streams.  We perform vacuum recovery of cleaning discharge to prevent entry into water ways.


Are there any problems with chemical cleaning?

Yes, if you use the wrong chemical or dilution rate, you can do damage.  Also, a lot of the chemicals are quite toxic if you touch or ingest.  This is why our technicians are fully qualified in chemical handling and health and safety.  We would never put them, or anyone, in a position where they could be harmed by chemical.
