Remove all Customers in Magento

I need remove all clients from my Magento install, because they have bad dates. I have 70,000 customers in my developed site. How can I do this with SQL?

  1. Make a BACKUP and test on a dev server first! This will DELETE all customer data including logs.

    -- reset customers
    TRUNCATE customer_address_entity;
    TRUNCATE customer_address_entity_datetime;
    TRUNCATE customer_address_entity_decimal;
    TRUNCATE customer_address_entity_int;
    TRUNCATE customer_address_entity_text;
    TRUNCATE customer_address_entity_varchar;
    TRUNCATE customer_entity;
    TRUNCATE customer_entity_datetime;
    TRUNCATE customer_entity_decimal;
    TRUNCATE customer_entity_int;
    TRUNCATE customer_entity_text;
    TRUNCATE customer_entity_varchar;
    TRUNCATE log_customer;
    TRUNCATE log_visitor;
    TRUNCATE log_visitor_info;
    ALTER TABLE customer_address_entity AUTO_INCREMENT=1;
    ALTER TABLE customer_address_entity_datetime AUTO_INCREMENT=1;
    ALTER TABLE customer_address_entity_decimal AUTO_INCREMENT=1;
    ALTER TABLE customer_address_entity_int AUTO_INCREMENT=1;
    ALTER TABLE customer_address_entity_text AUTO_INCREMENT=1;
    ALTER TABLE customer_address_entity_varchar AUTO_INCREMENT=1;
    ALTER TABLE customer_entity AUTO_INCREMENT=1;
    ALTER TABLE customer_entity_datetime AUTO_INCREMENT=1;
    ALTER TABLE customer_entity_decimal AUTO_INCREMENT=1;
    ALTER TABLE customer_entity_int AUTO_INCREMENT=1;
    ALTER TABLE customer_entity_text AUTO_INCREMENT=1;
    ALTER TABLE customer_entity_varchar AUTO_INCREMENT=1;
    ALTER TABLE log_customer AUTO_INCREMENT=1;
    ALTER TABLE log_visitor_info AUTO_INCREMENT=1;

  2. Mage::register('isSecureArea', true);
    $customers = Mage::getModel("customer/customer")->getCollection();
    foreach ($customers as $customer) {

    Be sure to know what you are doing though.. You can disable the customer as well if delete is not what you need.

  3. Or you just build a shell script and do something like that (not fast, but it is clean):

     * Starter
     * */
    public function run()
        ini_set('display_errors', 1);
        ini_set('memory_limit', '4096M');
        if (!$this->getArg('iknowwhatido') || $this->getArg('iknowwhatido') != 'yes') {
            echo "DEACTIVATED (call it with param '-iknowwhatido yes' to make it work!) n";
            return -1;
        Mage::register('isSecureArea', true);
        $customers = Mage::getModel("customer/customer")->getCollection()->delete();
