Hi All,
Any of u guys experiences prob that cement powder or small cement rock trapped on windows rail/track ? There are loads of powder trapped outside the balcony after air con installation and i'm really having a hard time as the powder flies in everytime i opened the windows. Anyone have any good idea/method on how to get rid of it ? I'm thinking to get a vacuum cleaner but not sure whether it is a good idea or not..


please advice.



thanks ...
