Spot removal

Hi all.
What to charge for spot removal per pane?
This is a post ccu.
Most of the windows have grids and had the protective film on. But there is a border around the film that only comes off using 0000 steel wool.

I’d price it like a CCU maybe alittle less but that’s me.

What’s the going rate?

I would typically try and get an additional 50% over what a standard clean would be.
