I'm telling a real story in the office. It was the employee’s birthday and they brought treats and goodies, initially realizing that it’s better not to take caramel with your bare hands - I recklessly grabbed it, of course. The result - although after washing your hands, some of the sweets managed to penetrate under the keys and freeze there, but there was very little of it, but it was a meager amount, but it happened. After a few hours, the most frequently used keys began to crackle and stick uncomfortably when retracted. The solution - I had to remove the crispy and jamming keys - Clean both the key inside and the pressure mechanism with alcohol. In summary - This keyboard should become alive for you. Handle it carefully, otherwise you will only get dissatisfaction and irritation from use.
