maverick: depends on how dirty your car is, if it has lots of grime and dirt hosing down without car shampoo is not enough, you might risk scratching your cars paint in the process. And nope di sayang pag wax mo, thats the purpose of wax to protect your cars paint from rain and the elements... its really hard to wash your car everyday, so what i do is have a routine like wash 2 - 3 times a week and detail during weekends. I just clean the windows everyday.
