something very strange while cleaning the keyboard

I bought a pressurized air duster today for removing dust between the keys, used it for the first time on the laptop, it did fine at the begining but when i went closer to the F1, F2, etc keys, it started to spread some kind of liquid on it. I imediatly took it away from the laptop and tried it on my palm, then on my normal PC keyboard, and everything was ok. Then i went back to my laptop, and started to spread some air near the space button, it spread liquid again. The notebook was turned off, unplugged everything from it. And i kept a decent distance when i pulverissed the air. What did i do wrong?

And i have a more important question, could those small ammounts of liquid damage my laptop in anyway, since it went in? I cleaned it with a towel, but some small ammounts went in.
The laptop is turned on now, since arround 10-15 minutes, and i did so for asking about it on this forums. Everything was fine till now.

 

Don't worry about the liquid on the keyboard, since it evaporates immediately, but keep in mind that it is a very cold liquid, so it could damage your screen or other sensitive parts from your laptop (from low temperature rather than being liquid).

That happens when you shake the can or tip it over. Be careful not to shake it or move it around too much prior to use, and keep it always in a vertical position.

btw, I always wondered the physical explanation for this phenomenon...

 

it should be ok ..you just pressed on the spray button to long/hard..and when its more or less tipped..like agusman said.
it will tell you on the back on the can that if you do that it will disperse liquid..well read the back of the can and you'll see what i mean.

 

thanx for the asnwers, pfew i was worried

Ah, and i wanted to ask about this, so i won't make a new thread about it.
What should i use for cleaning the laptop in general, and for the LCD.
I own a hp pavilion dv5 series, not sure from wich material is it made tho, i think its glossy.

 

i just use those electronic wipes you can get from walmart

they have always worked good for me.

pledge for electronics works well too..you can get that at officedepot

 

As stated before in other threads, I use 25% Isopropanol in double distilled water with a microfiber cloth for the screen, as well as the touchpad and all other external parts.

 

your laptop tested positive for viruses

 

Our IT Dept always uses the Shaggymac kits for cleaning.

 

The "compressed air" isn't really compressed air. It's a propellant that normally evaporates at a low temperature. To fit more per can it is compressed until it turns into liquid form(resting on the bottom of the can). When you push the button, the pressurized gas escapes and the liquid on the bottom evaporates.

Let me know if that's too vague, it's hard to explain without a graphic.
