What did you clean the keyboard with?

Looks like some of your bottom row keys are "doubling/repeating" with a few of the punctuation keys. For example the ç is produced with Alt-c, so the Alt key may be sticking, or just slow to release.

You may be able to tell something more by showing your keyboard viewer.
In Yosemite, that will be System Preferences/Keyboard, Click the box "Show Keyboard & Character viewers in menu bar".
Click on the new icon in your menu bar, then choose Show Keyboard viewer.
Type a few of the problem keys (n, m, b, Option/alt).

Pressing one key should trigger just that one key. Release the key, and the viewer should show that key turn off. It will quickly show "slow" keys, and sticking keys. Tap a stuck key a few times, which may help.
If you see a problem key or more, and a little "exercise" doesn't help, then you have likely too much moisture in the keyboard. You can try removing keycaps, and allowing it to dry more - but moisture (too much) can be the death of the keyboard.

Matreya unfortunately I used a spray to clean the plastic parts]. No doubt the problem is cause by moisture indeed].
