Enzymes for Carpet and Rugs

 Enzymes have been available to the professional cleaner for decades.  They are a great tool for dealing with any protein soil – food, urine, blood, etc.

Enzymes are catalysts produced by living organisms that accelerate biochemical reactions without being exhausted.  They are very specific to a reaction and the substrate they work on speeding up that reaction.  Fundamentally, enzymes transform construct, or break down molecules in the most efficient way know.

The enzyme, a digester, responsible for breaking up protein-based soil is called a broad substrate specific proteolysis enzyme or protease.  This enzyme can break down almost any type of protein into smaller units called amino acids, which can then be removed by conventional cleaning methods.

The enzyme responsible for the digestion of starch-based soil is called an amylase.  This enzyme breaks up starch into water-soluble sugars.  Examples are chocolate, baby food and gravy.

The third type of enzyme is called triacylglycerol lipase that is capable of breaking down animal and vegetable oils.  There are dozens and dozens of different enzymes, but on the cleaning side we are interested in proteases (protein soil), amylase (starchy soil) and lipases (oily soil).

What has been available to us for years are powdered enzyme prespray.  Taking enzymes and mixing with a detergent gives the product quick reaction with protein soil and synergism with the added detergent for great cleaning.  High pH can interfere with the enzyme reaction so look for a WoolSafe Approved product like MasterBlend’s Enzyme PreSpray.

A new approach to enzymes for deodorization is liquid bio-enzyme products.  The container actually contains non-pathogenic bacteria, which will product enzymes as it comes in contact with a protein food source.  This approach gives longer enzymatic action – continuing if it has moisture and a food source.

Liquid bio-enzymes can also be affected by high pH so look for a WoolSafe Approved product like MasterBlend’s UrineLock.

Locate the urine on the carpet with a UV light and saturate the area with UrineLock.  After a 20 minute dwell time extract with a wand or water-claw type device.  Then clean the carpet using the hot water extraction method.  Because UrineLock contains an encapsulation material a post-cleaning spray can be applied to the clean carpet without concern of resoiling.  It will continue to work until the carpet is dry.


For rug urine decontamination use one quart ofUrineLock for a 9 x 12 foot size rug mixed in 5 gallons of water.  First dust then place the rug in some type of soaking pit.  Pour the mixed product on the back and face of the rug.  Use a Rug Roller to work the product into the rug foundation.  Add fresh water to cover the rug soaking for 3 to 4 hours depending on the severity of the contamination.  Use the Rug Roller once each hour.  Drain the water and rinse while again rolling the rug.  Then clean and dry using your normal rug cleaning procedures.

 During the month of January contact Adco Pro Cleaning Supply 800 447-0677 mention Mikey’s Board and get 10% off a case of UrineLock and free freight.
