I believe that the world is divided between those of us who immediately remove the protective plastic from any gadget as soon as we acquire it and those who hold on with it until it becomes an opaque sheet. But these two groups immediately reconcile when it comes to cleaning: no one likes to have a tablet or smartphone screen full of fingerprints ..
There are times when, as soon as you clean the screen, more dust settles than there was before. Ditto with fingerprints. Let's see how we can avoid this and have the cleanest tablet in the whole city.
Avoid static on the tablet
The reason why the screen is filled with small fibers, which we can perceive by lowering the contrast in the lighting settings, is because they are attracted by static electricity ..
This occurs when the balance between the positive and negative charges of the atoms that make up the bodies is broken, the so-called triboelectric effect . Don't worry: the tablet is not leaking power. What happens is that by rubbing and cleaning the screen we have swept one charge and added another, so it tries to balance itself by attracting charges from the other polarity.
For this particular, the solution is an antistatic cloth . It is simply a small microfiber cloth. Duragadget is a brand that delivers great results; They have several very complete kits for tablets..
Of course: please, never use kitchen paper . They contain microscopic traces of wood, industrial cleaning, even some iron shavings. You will not notice it at first, but you will end up scratching the screen irreversibly.
Oleophobic gels
The hands are porous . Of course, they are full of life, they contain a microbiota, their own bacterial flora. In addition, they are one of the most exposed parts of the human body. By this I mean that the most logical thing is that if we put our fingers on the screen of the tablet, the fat particles leave a slightly marked film. Unpleasant, right?
Well, the solution does not require a special effort either: oleophobic gels . Or, what is the same, anti-oil, from the Latin oleum , "oil." Most mid-range and high-end tablets and smartphones include a very thin - approximately 0.4 mm - tempered glass that protects against this, but over time they lose effectiveness.
If we cannot get an oleophobic liquid, we can use a little neutral soap with water - better if it is distilled, as it contains fewer impurities, or bottled, better to avoid tap water. We can also use medicinal alcohol, which is not pure, diluted with water. Alcohol by itself is somewhat abrasive, but reduced to 50% it offers us its properties without damaging the terminal. Fortunately, more and more tablets include higher IPY and IPX degrees of protection.
Wash your hands, drop those Doritos!
We already know what happens when we leave the tablet to the smallest of the house. One of the biggest enemies of tablets is food . The chemical composition of some colorants or foods can deteriorate the screen protection polymer. For this particular the correct thing is to carry out a quick cleaning operation.
First, turn off the tablet, then wet the suede that we recommended above, or even a glasses cloth if you have at home, and rub in small circles, from the inside out and applying very little pressure. Removing any possible remains of liquid with the dry part, then let it dry - do not use paper or you will smear it again - at room temperature. Then, and only then, turn your tablet back on.
Utensils for all kinds of budgets
There are palm-grip mops, such as Targus CleanVu, which is made up of a scratch-resistant synthetic suede-sponge and a leather outer coating. On the other hand, we have rollers like this one from Colocolo, which emulates a paint roller and, in a single pass, removes dirt fluff and provides antistatic protection. 
Never remove the protective plastic
Yes, we know it is a nuisance, but if you live in areas affected by sand, such as coastal cities, or places where the air carries too much dust, this is a solution to extend the useful life of your terminal. You can try to restore the screen with a few drops of oleophobic solutions , but even the slightest friction will drag sand particles and scratch the screen. Hence we need a more invasive protector.
And we could still recommend cases and covers, which Lenovo itself distributes for all its products. They are the ideal complement and will protect you much better for moments where you have to move or simply stop using the tablet.
