Oily/greasy look when using a screen protector…

I just got the new iPhone and got a glass screen protector from Walmart brand onn. I had the same brand on my last iPhone but for some reason this one makes my screen look like it’s constantly greasy/smudged all over and I absolutely HATE that. I feel like I need to constantly wipe the screen. Are there any brands that don’t do this? I don’t want to buy a crap ton of different protectors just to find one so I’m hopefully asking here.
