Hi ! guys is there anybody know or have already done cleaning inside the headlight,Coz my 9004 hyper white bulb burst inside the headlight and some kind of a powder was all over the chrome reflector .please help me ASAP!!!

You can use just plain ol' H2O to rinse out the stuff. To get the moisture out, empty the housing out first and then pour some rubbing alcohol into the housing. It will mix with what ever water is left and then just drain out. The alcohol will evaporate much faster than the water will and youll be back on the road with one headlight....hehe...good luck.

i also have something to add to that is there a way you can pull the glas cover off? and how do you do that.... Or do you have to take the whole unit out..?

The lenses on the headlight are plastic and are "welded" to the rest of the housing unit. You have to take the whole thing out.
