We have 2 identical faucet. We change the aerator of 1 without trouble. The second one is not staying in place. We tried to put some silicone around the threaded faucet, but it is not working. We are thinking that when we unscrew the aerator, the internal threaded must have some deposit and today it is too loose. What can we do ?

A bit late, but for anyone still wondering I had this problem today. I took two forks and put one prong on each into those little notches and turned counter clockwise until I felt it becoming loose. At that point, I just had to unscrew it a bit more and it came off.
There are many sizes of faucet aerator threads. You can get an idea from the picture of the thread gauge below that you will typically see at a better equipped hardware store where aerator units are sold. (In my experience typical for a USA hardware store. Your situation may vary depending upon your geographical region).
The thread gauge above supports the following thread sizes:
1/4-18 (M)
1/4-18 (F)
3/8-18 (M)
3/8-18 (F)
1/2-27 (F)
1/2-IPS (F)
9/16-24 (M)
5/8-18 (M)
5/8-24 (M)
5/8-27 (M)
11/16-24 (M)

3/4-11 (F)
3/4-27 (F)
13/16-20 (M)
13/16-24 (M)
13/16-24 (F)
55/64-27 (F)
15/16-24 (M)
15/16-27 (M)
*(F) Denotes stud used to determine female thread size
*(M) Denotes tapped hole used to determine male thread size
Add in metric sizes from other parts of the world and this list is likely to grow considerably.

Take a rag soaked in lemon juice, vinegar or CLR and shove it up into the faucet against the internal threads for a few hours. Keep re-soaking the rag. Then brush the threads with a toothbrush and reinstall the aerator. Remember to use the washer that came with the aerator. Oh, don't use the toothbrush on your teeth...
