How to Clean With Real Precision

Modern world where we all live in is a place which we are familiar with and have a basic idea about but that is why when someone tell us the word “cleaning” the first things that come up in our minds are cloths and cleaning solutions. However, the truth is that there are different methods and different things to be cleaned so that the cleaning can be extremely different from what many of us imagine. It can actually be an extremely complicated job with great importance.

So, what sort of cleaning can be there that to be so different from the one we know?

Well, the cleaning of the telescope lenses is the one we are talking in particular. It is important because of the principles used by the telescopes in order for them to work. What they do is to collect huge amounts of light and this way to be able to see further. One of the biggest lenses in the world is 10 metres in diameter which really means that the telescope can see far away (actually to end of the universe). However, if there is something on the lens, it will make it collect less light and will disturb the image, which is not what the scientists want.

So, how the lenses of the telescopes are being cleaned?

The main principle used in the case is the one of the sand blasting but on a different scale.

So, what is sandblasting, who invented it and in what way this is related with the cleaning of the lenses?

A general in the union army named Benjamin Chew Tilghman was fighting in the desert in 1871 and saw patterns edged on the windows by sand blown by the desert winds. Thanks to this, he came up with a brilliant idea – to create a machine that blows sand through a nozzle on a surface and clean it this way. The way the whole concept was created is a legend but it is a fact the Tilghman created a sandblasting machine. Today, his machine can be found anywhere in the world where people remove paint, rust or dirt.
However, cleaning a huge lens with a microfibre cloth is not gentle enough and causes scratches so how can such an invention like the sandblaster to be helpful when we all know that it is a million time less precise. The actual machine that cleans the lenses uses the same principle but not on microscopic but on an atom level( which is even smaller). The machine used for the job blasts atoms on the surface of the mirror at high speed.

How the atom blasting machine works?

The first thing is to glue the thing you are about to atom blast and then freeze it with liquid nitrogen. Once that done, the “thing” goes in to the blasting machine where most of the job is done by a robot because of the precision that is needed which is impossible to achieve by human.
Then, the people working, go to a computer where they can zoom out or in reaching scales which allow them literally to see the atoms. This way, they can position the machine under a precise angle and clean the surface of the mirror atom by atom leaving it absolutely clean. Such cleaning, on such level and for such mirrors takes weeks but it is worth it.
The final thing of the procedure is when the mirror is cleaned with a jet of CO2.

However, if you need to have a normal cleaning procedure, you surely do not need such an equipment like the scientists. You only need a duster and a cleaning solution or you can hire professional cleaners Camden for the job. These guys are well aware of the needed actions when someone wants a clean home, so they can deliver quality right away.

Therefore, cleaning can mean so much more than we imagine but when it comes to the house cleaning, the procedures are pretty much the same as they were when our grandmothers were cleaning their houses, 60 years ago.
