Disable Sidebar in the Product Page in Storefront Theme [closed]

for product page, you can put in functions.php

function remove_storefront_sidebar() {
    if ( is_product() ) {
    remove_action( 'storefront_sidebar', 'storefront_get_sidebar', 10 );
    }
}
add_action( 'get_header', 'remove_storefront_sidebar' );

It works with latest woocommerce 2.5.2
Also CSS is needed:

.single-product.right-sidebar .content-area {
  float: none;
  margin-right: 0;
  width: 100%;
}
