White spots showing up after making background transparent
I've been working on my team's logo for a f1 schools competition. I've managed to erase the whole background, yet there are still some white spots which I can't get rid of with the eraser. I'm fairly new to photoshop so I'm not sure how to remove these spots. Here's the current png:

When viewed from the Windows Photos app, the white spots are clearly visible:

Any help would be appreciated! Thank's
