How to clean ingrained dirt from quick step laminate flooring?

This is quick step laminate in my grandparents home, been here for well over 10 years. I’ve tried scrubbing the floor with soapy water but the floor is still dark. It’s meant to be the light yellowy colour you see on the very left plank. Does anyone have any ideas on how to clean it? Or are we better off replacing it (last option)

Is this colour bleed? Sprayed Shout on a stain and it came out like this.

Toddler smooshed strawberries into his pjs. Sprayed the stain with Shout when it was still pretty fresh, let it sit for a few minutes, then did laundry on cold. Shirt came out like this. I’m assuming there’s no way to get this out? Does this look like colour bleed/dye transfer?

How to remove this stain?

I don't know what caused it I already tried baking soda with water and two stain removers. I think it has helped because the stains aren't as redish as before I think the fabric is made out of cotton but I'm not sure. It's a top I bought at Bizzbee Thank you in advance!
