you need to use jquery after the payment on thank you page: jQuery(document).ready(function () { paypal.minicart.reset(); });

You can check the CSS file. may be delete but showing only mouse hover.

if you want to save cart value in database or want to show cart on checkout page then you need to use jquery + ajax. Like var items = paypal.minicart.cart.items();...
