00:00 Hi everyone! We're not going to lie, we all hate cleaning, but sometimes it's really
00:05 interesting to watch. In our video of the day, we're going to show you a deep cleaning
00:09 of the most surprising and the most neglected things at the same time. Whether it's
00:13 swimming pools, paintings, solar panels or even central units, they will be renewed.
00:17 So let's go!
00:18 For some, washing the roofs of houses may seem absurd, but you will not deny that
00:26 the tiles cleaned in this video are 100 times more beautiful than the tiles that are scratched,
00:30 isn't it?
00:31 It is also a special device developed by the German company Aquajet, which is a kind
00:34 of vacuum cleaner for you.
00:36 Oil is one of the most corious substances, and it is very difficult to get rid of it,
00:45 especially when it comes to the discharge of hydrocarbons at sea and on the surface of
00:48 the seas.
00:49 In the United States, we have developed a relatively cheap, effective and ecological method
00:56 to clean them.
00:57 A special powder capable of absorbing up to 10 times its own weight.
01:00 But above all, it is very easy and safe to collect, because it somehow traps the oil
01:04 inside.
01:05 This powder is made from polysulfur and other polymers.
01:08 This is what the process of cleaning oil in miniature water looks like.
01:21 Ships must be cleaned both on the surface and in depth.
01:23 Their cleanliness has a direct impact on their speed of travel and, consequently,
01:28 on their fuel consumption, just like planes.
01:30 If the bottom of the hull is not cleaned for a long period, it is invaded by
01:33 entire algae colonies and other marine organisms, and the ship loses up to a third of its speed.
01:38 It is also very important to clean the propellers carefully so that they continue to work.
01:42 Special robotic machines are used for this.
01:44 They are equipped with hundreds of small brushes and also use a hydrocavitation technique,
01:48 that is to say that they clean by emitting a jet of water.
01:51 The hydraulic power of these devices is so high that they can eliminate the most
01:54 tenacious dirt.
01:55 Any other person would have simply thrown this poor pair of sneakers.
02:01 But this guy doesn't back down from anything, not even from cement stuck to his shoes.
02:04 And for good reason, this is what he managed to accomplish with hot water, detergents,
02:08 a pencil and a brush.
02:10 Here is what the cleaning of an old revolver looks like, almost entirely covered in rust.
02:38 First of all, the weapon is placed in a special solution to eliminate corrosion.
02:42 Then, a long and meticulous disassembly, return and work process is started
02:47 on each of the parts.
02:48 the metal objects, in stone and glass, particularly dirty, are cleaned with
03:14 sand.
03:15 In the case of laser, this method is even used to clean human teeth.
03:18 Sand or special powder is sprayed using a powerful jet of air.
03:21 We use this same technology to cut off the upper layers of car paint.
03:25 Metal is often cleaned with another impressive method, laser cleaning.
03:36 The advantage of this technology is that it does not come into contact with the material,
03:46 and therefore does not damage the fragile surfaces.
03:48 It is also extremely precise.
03:50 Here is an amazing fact that you may not know.
04:04 Contemporary planes are repainted every 7 to 8 years.
04:07 This Airbus A380 for example was repainted by a team of no less than 34 specialists.
04:12 It took 6,000 hours of work and more than a ton of paint.
04:15 First of all, the old coating is cleaned with a solvent.
04:18 Then, the plane is covered with several layers of spray paint and transparent layers.
04:22 It is these that make planes have to be repainted after a few years.
04:26 Indeed, due to temperature variations, the polished surface cracks, and it is strictly
04:31 forbidden to fly on a plane whose coating is damaged.
04:33 This is dangerous.
04:34 Sometimes, it is necessary to repaint the plane when it is sold to another company.
04:39 In addition, of course, planes are regularly washed, 2 or 3 times a month if they are used
04:43 actively.
04:44 For this, we even invented modern machines with rotary brush brushes.
04:48 Without them, the manual washing process takes much longer, from 4 to 8 hours.
04:53 Moreover, planes are not washed only for aesthetic reasons.
04:56 The dirt on the surface of the plane increases fuel consumption, and negatively affects
05:00 aerodynamics.
05:01 It's scary to imagine how we got there.
05:03 But it doesn't matter, because we can even remedy such a disaster.
05:06 First of all, you have to pump all the water from this basin.
05:08 Then, we wash the ground and release the frogs in captivity, if there are any, as in
05:16 this case.
05:17 After that, we remove the coating from the walls and the ground, if there is any, and
05:20 we clean everything that is underneath.
05:21 We have the impression of being able to feel even through the screen.
05:27 The whole thing ends with the laying of a new coating on the dry concrete, the filling
05:34 of the pool, and its renewal.
05:35 Believe us, if you disassemble your keyboard, you can find a whole lot of raw materials
05:46 inside.
05:47 Like for example, an isolated grain, as in this case.
05:49 But therefore admire this remarkable work.
05:55 In fact, the central unit can also accumulate a lot of dust.
05:58 But it's good to see that even such desperate cases can shine a thousand times once
06:01 more.
06:02 Here we go.
06:03 Here we go.
