Ur MOST Welcome!
As for LAATEE Reply!! I was busy in ma studies!
Well it took some time for me also in Understanding Abbreviations But later on U'll get it from wikipedia or Mobile Dictionaries(Mostly)
For Ur dirt problem i think U should discuss it on the Car Detailing forum! With some attached Pics!!
From my side I can give u Following precautions:
1.Wash it on day time Bcz in Evening or night water takes long time to dry & remains on surface resulting in bad looking spots
2.After washing of soap dry it with a soft towel( To maintain towel's softness i'll dip it in little amount of Comfort conditioner)
3.Or there are some specialized clothes available for drying Car's surface( I don't experienced them yet)
Otherwise disscuss it on Carcare Forum Im pretty much sure U'll get Very positive response (As per my experience)
