Dusting the leaves of Valencia orange, Balady guava and Gharibi grape increased most of the nutrients content, especially in the case of guavas and grapes. Meanwhile, dust contamination did not affect either chlorophyll or total carbohydrate contents of the leaves collected from all the experimental plants. The different cleaning procedures seemed to be more effective in removing dust contamination from smooth waxy surfaced orange leaves. On the contrary, rough and pubescent leaves of guava and Gharibi grape responded less to the effect of the different cleaning procedures in removing dust.
