As soon as you select a product attribute (by default, this is a dropdown right above the variation add to cart button), a “Clear” button appears beside the dropdown/s in order to reset the selection/s and start anew.
As usual, some WooCommerce store owners may require to hide/delete such link, and this is why your truly is here: why “display:none” stuff with CSS when you’re not actually removing it completely from the code? Which means, there must be a PHP way.
And, once again, here comes a 1-line snippet. Enjoy!
PHP Snippet: Remove Reset Variations Link @ Variable Product Page
You can place PHP snippets at the bottom of your child theme functions.php file (delete "?>" if you have it there). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"
Does this snippet (still) work?
Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7.3.
