remove on sale tag

Hello,

I upgraded woo and my themes to the current versions and tried to get rid of the sale tags in products and product listings with this function:

remove_action( 'woocommerce_before_shop_loop_item_title', 'woocommerce_show_product_loop_sale_flash', 10 );
remove_action( 'woocommerce_before_single_product_summary', 'woocommerce_show_product_sale_flash', 10 );

it worked for the product details page but not for the product listings.

any idea doing that without css?
Thanks
Tom
