Can't even try the product

Ordered the product since it has a good reputation in terms of its tripods, but was let down. On unboxing, there are stickers attached to the polarizer that left extremely stubborn sticker residue marks. I have tried both alcohol and heat to remove to no accord.

About Sirui Brass Circular Polarizer

SIRUI Ultra Slim S-Pro Nano MC Circular Polarising Filter - stops reflections from water and glass surfaces

The SIRUI Ultra Slim S-Pro Nano MC Circular Polarising Filter increases the colour saturation of the image, meaning whiter clouds and a bluer sky, for example. The filter also reduces reflections from non-metallic surfaces (water or glass). Thanks to its high quality, the SIRUI Polarising Filter achieves a polarisation rate of nearly 100%.
