Best way to remove bike downtube label?

My 12yo son is joining his school's mountain biking team, but he is embarrassed that I got him a Ozark Trail Ridge M.2 last year. He wrapped the downtube with black electrical tape to cover the label. He says kids will know it is a Walmart bike.

Is there an easy way for me to remove the "Ozark Trail" label? Maybe scraping it off with a straight edge, acetone, or a heat gun?
