If you wash more than once a month — then yes! And if you’re washing less than twice a month, you’re doing your vehicle a disservice: South Florida’s harsh elements wear on it every single day. Washing weekly on a membership can save up to $765 a year versus paying per wash — plus 25% off interior and detail services, good at every Mint Eco location, with no contract. Your savings start on your very second wash of the month.
