Posted by Ollie Nelson on

If you run a restaurant, bar, or pub, you know the importance of having clean and sparkling glassware for your customers. However, dealing with pink slime in your commercial glasswasher can be quite frustrating. Fear not! In this detailed guide, we'll take you through everything you need to know about pink slime, its causes, and, most importantly, how to effectively tackle it. Let's ensure your glass washer operates smoothly, leaving your glassware spotless and your customers impressed.

Understanding Pink Slime

What is Pink Slime?

Pink slime, also known as biofilm, is a slimy, pink deposit that can form inside the water lines and components of your commercial glass washer. It's not a single organism but rather a community of various microorganisms, including bacteria, fungi, algae, and more. These microorganisms love warm and moist environments, making glasswashers a perfect breeding ground for them.

Causes of Pink Slime Formation

Why Does Pink Slime Form?

Pink slime doesn't magically appear; several factors contribute to its growth, including:

  • Warm and Moist Environment: Glasswashers use high temperatures for proper cleaning, creating an ideal environment for microorganisms to thrive.
  • Leftover Organic Matter: Residual food particles, soap residues, and other organic substances act as a food source for the microorganisms, promoting their growth.
  • Stagnant Water: Inactive periods or low usage can lead to stagnant water, creating a breeding ground for pink slime.
  • Water Quality: Hard water with high mineral content can lead to mineral buildup, providing additional surfaces for biofilm attachment.
  • Inadequate Cleaning and Maintenance: Neglecting regular cleaning and maintenance allows pink slime to accumulate and persist.

Dealing with Pink Slime: Solutions

How to Tackle Pink Slime?

To combat pink slime effectively, follow these steps:

Regular Cleaning Routine

  • Clean your glasswasher daily, paying particular attention to wash and rinse arms, jets, nozzles, and filters.
  • Remove visible debris and organic matter to discourage pink slime growth.

Sanitisation is Key

  • Use a high-quality cabinet glasswasher detergent with the right dosing equipment as per the manufacturer's recommendations.
  • Proper sanitisation kills harmful microorganisms and helps remove existing pink slime.

Deep Cleaning

  • Perform a thorough deep clean at least once a week, focusing on hidden areas where pink slime can accumulate.
  • Take apart removable components and clean them meticulously.

Prevent Stagnation

  • Avoid extended periods of inactivity by running your glass washer regularly.
  • If the machine hasn't been used for a while, flush the water lines and components before use.

Control Temperature and Humidity

  • Monitor the ambient temperature and humidity around your commercial glasswasher to discourage microbial growth.
  • Configure your machine for a 55°C wash temperature and a 70 to 75°C rinse temperature.

Proper Drying

  • Ensure your glass washer and its components dry thoroughly after each use to minimise moisture retention.
