How can I remove the cart icon from my one-click checkout page?

Hey Ninjas, 

The site is www.copperquench.com. PW: copper63

It's a one-product shop. So, you won't see a cart or a button related to a cart. Now, the issue is while I updated to a one-click checkout option, the cart icon is visible at checkout. How to remove it.
Note: Right-click is disabled on the site. Please use 'CTRL+Shift+I' to inspect the element, if needed.

Thanks in advance, if somebody could solve it!
