Window Cleanze is a water fed pole window cleaning additive. It enables faster cleaning and a more consistent result.
Does not increase Total Dissolved Solids (TDS)
"I used Window Cleanze today and to be honest I didn't think 5ml in my 500L pure water tank would make a difference.
"What a surprise!
The brush glided more easily across the glass. It made it more efficient and quicker to remove bird mess and snail trials.
It enabled me to work quicker and I used less water.
"The BIG question was: Can you use Window Cleanze before the DI vessel (resin)?
YES YOU CAN! I used 350L of pure water, tds is the same, and it didn't affect the resin. Your product is great!" Ben Merigaux, Jurassic Coast Window Cleaning
Adding Window Cleanze to purified water helps some types of glass become more hydrophillic. For the types of glass that respond, you'll be amazed at how your brush will much more easily glide across the glass.

What's the daily cost of Window Cleanze?
Because it's highly concentrated Window Cleanze only costs 0.25 - 0.75 euros/pounds a day. This assumes a dosing ratio of 1-5ml per 100L of pure water and a window cleaner using 500L of water per day.
"I've been using Benz Window Cleanze for the last few weeks and I couldn’t recommend it highly enough. It cleans the windows so much faster and really helps the frames. I love it" Tim Anderson, TruWASH

Application guide
After adding Window Cleanze to your de-ionised water, clean windows as normal. You'll notice how much easier it is to clean the glass and the frames. And you'll notice how bird's mess and snail trails dissolve much more quickly.
Btw: Window Cleanze treated water may leach more residual dirt from the window seals than does de-ionised water alone. No problem, just give an extra rinse during the first clean.
Also, you may notice "bubbles" streaming down the glass. This is normal.

FAQ (Frequently Asked Questions)
Yes. Many customers now choose biodegradable products whenever they can and look favourably on contractors who use them.
This varies according to dosage and the quantity of water used. One 500ml bottle will treat up to 50,000 litres of water, so if you use 1000 litres a week one bottle will last you up to 12 months.
What Dosage Should I Use?
We recommend 1-3 ml per 100 L of water (5-10 ml in a 500 L tank).
Use 3ml if you have a lot of first cleans do do on a particular day. For regular, repeat cleans 1-2ml will be fine, with 2ml being the most common.
Experiment with increasing and decreasing the dosage, as different environments and qualities of glass have differing requirements. Start at the lowest level and gradually increase until you find the optimum strength.
Can Window Cleanze be used to clean uPVC?
Yes. You can use Window Cleanze on all surfaces, including uPVC and conservatory roofs.
Allowing it to activate for a short time will enhance its effectiveness, as is the case with all surfactants, but is not essential.
When cleaning windows for example there is no necessity to allow Window Cleanze to activate. Simply add it to your de-ionised water and work normally, treating the sills and frames at the same time, as an integral part of the cleaning process.
Quick tip: For cleaning uPVC sills, frames, soffit, fascia and gutters that are seriously dirty we recommend first treating them with Benz Lightning Cleanze diluted 10:1.
Use Window Cleanze for ongoing, regular cleaning to keep uPVC looking good.

Can Window Cleanse be used in warm water?
Yes. Warm water enables Window Cleanze to clean even more deeply.
Does Window Cleanse affect TDS (Total Dissolved Solids)?
No
Can Window Cleanze be used to clean the insides of windows?
Yes
Can Window Cleanze be used to clean mirrors?
Yes
What does Window Cleanze smell like?
Concentrated Window Cleanze has a pleasant aroma. You'll notice this when using it at high dilution, although at low dilution it may not be so noticeable.
Window Cleanze can improve the sheeting on some hydrophobic glass, which enables the glass to rinse more easily at lower flow rates. The level of improvement depends on the nature of the glass and level of dosage.
