What are Scrubs for Window Weapon?
First let’s talk about agitation and why we even need scrubs.
Well there are three ways to agitate glass you can either:
scratch something off
scrape something off
grab something off
What Reach-iT have done is develop the Window Weapon to remove the non water-solubles or the things that won’t come off with water and scratching by a brush alone.
Currently there are a whole range of things that a traditional window cleaner could use if they wanted to get these non water-solubles off of the glass. They could choose a white non scratch pad such as a magic eraser, or they could use their steel wool or a bronze wool and they will of course have a trusty scraper blade in their bag as a last resort. So all of these are either going to scrape or grab something off the glass.
Reach-iT have made it so that you can take that debris off of the glass and what’s unique about Window Weapon is that you can do this in one single action. You can agitate on the upstroke and rinse on the downstroke.
This means no off glass rinsing which makes it not only more efficient but it is also hugely effective.
You can also interchange your scrubs as you get used to using them and find which ones work best for you on different types of non water-solubles.
Nylon bristles from a traditional water fed brush uses a scratch method.
The bristles are at right angles to the glass surface so they’re scratching things off of glass.
There are many types of non water-solubles on glass that you can’t get off with a normal brush until the Window Weapon came along.
When using a scrape style scrub the agitating surface is running up parallel to the glass so it’s scraping things off the glass.
It’s a myth that you have to use triple zero or quadruple zero steel wool or otherwise it will scratch the glass.
White Non Scratch Pad
The white non scratch pad is a scrape action. With the white non scratch pad at 90 degrees to the glass, whilst using it you are running and scraping up the glass as you agitate.
Many people don’t know what a white non scratch pad is. It is basically a plastic or sometimes a mix of plastics and in the middle is a very fine powder (similar to cerium oxide – a powder that will clean glass). If you were to tear it open you would see this dust blow out and it’s that dust which is your non scratch agitator mixed up with the synthetic strands.
This was originally added for free with the brush as Reach-iT didn’t really know at the time whether it would make a big difference or not. They knew that the traditional window cleaner would always carry it with them (as they know that these can take silicon off glass etc). So once it was proven that this was a very valuable tool, Reach-iT added it as a permanent feature of the Window Weapon kit.
The second most popular scrub is the blue metal scrub. Blue metal is actually a fabric from the industrial cleaning industry used in kitchens. It is used for cleaning dishes, plates, glasses and you’ll see this type of material usually filled with sponge when being used in this application.
This material is made from stainless steel woven into polyester. So the blue material is polyester and the silver running through it is stainless steel. It is set at a very tight amplitude or curve so that each stainless steel fibre has a very powerful cutting edge (again it’s parallel to the glass so it’s a great scraper).
This is similar to the commonly used brillo that you would find in your kitchen cupboard. This may be used to clean kitchen utensils and it’s great at not scratching your glass as it has a much bigger amplitude. This means that it is a lot more curvy so it’s much more like a blade that cuts underneath whatever is on the glass.
This scrub has also had some fantastic results with removing artillery fungus and things like that, it really is a great scraper.
There is also a range of bronze wool scrubs incorporating bronze mesh which is a tight mesh, a medium mesh and then there’s the bronze wool scrub itself.
Again these are all scraper scrubs that Reach-iT have designed in order to help you clean windows faster, better, safer.
Green Rubber (TPR)
This has a woven finish and when it runs on the glass it grabs debris off and it’s the second most popular scrub so far for everyday use.
One application for this is removing bee poo. You can scratch bee poo with a normal brush if you just scrub and scrub and scrub but you can never get rid of the waxy residue which leaves an oily stain on the glass. The best way to do this it to use the green rubber scrub to grab all of the residue off of the glass in a quick and easy way.
Some window cleaners like the microfibre scrub and feel that it is a good addition. However a concern with microfibre which is a grabber is that when you get a bit of debris in the microfibre it has nowhere to go once its been grabbed.
If you look at all of the other scrubs other than microfibre the water can flush a grain of dirt or sand or grit out and it can go backwards into the scrub and be flushed out. The microfibre scrub can’t do this, so if you do get something caught in your microfibre scrub then it is potentially going to scratch glass as you continue to use it.
The reason that it is still included is that if you are dealing with trying to remove hydrocarbons or smoke such as in a factory area where there is a smoke stack then your microfibre scrub along with a detergent can break down all of the hydrocarbons and you can carry on cleaning and rinsing as normal.
When using any of these scrubs it is up to you as the professional window cleaner to do a little test on an area of glass before using it to make sure that the scrub won’t leave any marks or refraction on the glass. None of the scrubs will scratch glass, what they might do is scratch a surface on the glass or an oxidation or a film that is covering the glass. If the result is ok on your test area then the glass should be safe to clean using that scrub.
How to do a test
Use two fingers pressing the scrub against the glass and rub 10-20 times you will see if the scrub is going to scratch the window. If you are happy with the result you should be able to use the scrub safely.
