also, is carnauba wax good for a white car? im thinking of getting this instead of a regular wax kasi eh (if this is any good).
For a white car, a cleaner wax will be your best friend, if you have time contraints. You can top off with a good carnuba wax (Mothers, Megs are good choices)

You might want to try the citrus shampoo of Big Berts, bang for the buck talaga, for around 400 petot you get a gallon worth. Good for around half a year.
