How To Clean Shower Heads Effectively and Easily.

Prevent Legionnaires Disease with these easy steps…

When talking about water hygiene and clean water, the number one risk to human health and life is Legionella bacteria, that can lead to Legionnaires Disease. If contracted, Legionnaires Disease can cause serious health issues. Even if you are otherwise fit and well, you have about a 1 in 10 chance of dying. Survivors often experience long term debilitating conditions such as damage to respiratory systems, acute kidney failure, sepsis, loss of limbs, and more.

All cases of Legionnaires Disease are caused by inhalation of water ‘aerosols’ containing Legionella bacteria. These aerosols can be caused by domestic showers as they produce water droplets, often at high pressure, and of varying sizes.

As inhalation of airborne water droplets is the main route of infection for Legionellosis, showers pose a high risk, highlighting the importance of understanding how to clean shower heads effectively in order to improve cleanliness, reduce scale and bacterial contaminants within the shower head and hose, and to minimise the risk of contracting Legionnaires Disease.

If you feel that you need training in the area of Legionnaires Disease risk management for your business, please visit our training website HERE.

Whilst anyone can contract Legionellosis, certain conditions put individuals at higher risk:

  • Over 50 years of age
  • Smokers
  • Heavy drinkers
  • People suffering from chronic repository or kidney disease, diabetes, lung and heart disease
  • Anyone with an impaired immune system

To reduce the risk of Legionella growth the HSE recommends the cleaning and descaling of shower heads and hoses at least every 3 months, which is why it is important to understand how to clean shower heads effectively and thoroughly.


How To Clean Shower Heads?

Often people think that typical household cleaning solutions are the best method to clean shower heads and hoses, but unfortunately, these fail in several areas:

  1. Most products only work to descale the surface of the shower head, and don’t penetrate the inside where the majority of bacteria reside and thrive
  2. Most products do not sterilise or disinfect any part of the shower head
  3. Most products don’t allow themselves to be diluted sufficiently and cost-effectively to allow full submersion in a bucket or similar container to allow the shower head and hose to soak for a period of time (optional, but a good idea for a guaranteed deep clean)

When it comes to cleaning your shower heads and hoses the very popular and well-known Showerhead Plus range of liquids and gels has proven effectiveness in legionella (and other) bacteria control.It does this by effectively removing both scale deposits and bacterial contaminants inside and outside of the shower head and hose, and is even suitable for chrome fittings at the right dilution.

The Showerhead Plus range is available in 10 Litres, 5 litres and 500ml Gel containers, allowing you to choose the right size container for your needs, and giving you the freedom to dilute the solution as you see fit for your requirements.

Shower Head Plus is an acid based, ready to use descaling solution encompassing a proprietary biocide.
