Traditional vs pure water window cleaning

What is traditional window cleaning?

Traditional window cleaning just involves using a mop and squeegee. In fact, its even referred to as the ‘mop and squeegee’ method by some.

This is probably the first type of window cleaning that springs to mind. The reason for this is because, for a long time, it was the standard window cleaning method used by everyone.

However, regulations from the Health and Safety Executive now state that you must avoid work at height where possible. This means using telescopic water fed poles rather than ladders, which is where pure water window cleaning comes into play.

Whilst it may no longer be the most popular technique, traditional window cleaning still has a time and place. For example, it’s ideal for making interior windows sparkly clean!

Advantages of traditional window cleaning

• Window cleaning is all done by hand
• Windows are dried immediately after being cleaned
• Able to achieve a consistent finish

Disadvantages of traditional window cleaning

• UK Health & Safety law means traditional window cleaning is only allowed up to the first floor with proper precautions
• Cleaning products used with this method may leave a clear film on the glass causing them to get dirtier quicker
• There’s a chance of causing damage to a property when using ladders

What is pure water window cleaning?

Sometimes called ‘reach and wash’, pure water window cleaning is a more modern method.

Essentially, pure water, also known as ‘deionised water’, means that all the natural minerals have been removed. This is achieved by filtering through a purification system.

The reason that using pure water is so important is because you can leave it to dry on its own. Instead of possible film or spots, which could happen using standard water, pure water ensures a flawless streak-free finish.

We’ll explain more about the process involved with filtering the water through a purification system in a separate section below. For now, we’ll continue with explaining how this method of window cleaning works.

Once you’ve got pure water along with the appropriate equipment (i.e. a water-fed pole and brush), you’re pretty much ready to go.

For the best results with this method, you’ll first need to use your water-fed pole and brush to agitate any dirt or build-up. Doing this helps to loosen any dirt and achieve the cleanest finish in the end.

After this, you should be able to give the window a final rinse with the pure water and leave to dry naturally. If this isn’t done properly and there’s still some dirt behind, the pure water won’t look clean once dry.

That’s why it’s best to start cleaning the windows at the top. Then you can move left to right as you go down ensuring that all dirt and build-up is fully removed.

Advantages of pure water window cleaning

• It’s a safer method, especially for higher or inaccessible windows
• Using pure water means windows will dry clear and streak-free on its own
• Can be faster than traditional window cleaning

Disadvantages of pure water window cleaning

• Not quite as effective for interior or hard to reach windows
• The water-fed pole may malfunction
• Makes it harder to clean really dirty windows

How to make pure water for window cleaning

To get started with making your own pure water for window cleaning you’ll need the following:

• A water source (e.g. tap water)
• TDS meter
• Resin
• DI vessel
• Reverse osmosis system (for hard water only)

Below are the two main steps for making purified water suitable for window cleaning:

Use a TDS meter to tell whether the water is soft or hard

First of all, you’ll need to test how hard the water is that you’re using with a TDS meter. If the reading is around 20 or below, then you have soft water. This means you only need a DI vessel and resin to purify it.

A reading of above 150 means that have hard water, so the water is full of chemicals and minerals. If you’re working with hard water, then you’ll also need to use a reverse osmosis system.

Filter your water using deionisation and reverse osmosis systems

It’s important to know that for pure water, you’ll need a reading of below 0.07. To bring down the meter reading you’ll need to filter the water.

As mentioned for soft water you’ll just need a DI vessel and resin. Start by making sure the tank is full of resin and then connect the water supply to the DI vessel. As the water runs through, the resin will filter it releasing purified water.

Meanwhile, when it comes to hard water, you’ll need to use a Reverse Osmosis System for the first round of filtering. This works similarly where you just connect the water source to the vessels. After you’ve done this, you’ll want to measure it again using the TDS meter. If the reading isn’t right, you’ll need to filter it again.

There are various pure water systems available to suit different needs and budgets. Alternatively, you can just buy purified water directly.

Which is better – traditional or pure water window cleaning?

Ultimately, both methods of window cleaning have their pros and cons. The main thing is to use the right one at the right time as certain situations call for a particular method. It’s also important for window cleaners who’ve been in the job a while to be able to adapt to these new methods.
