Wynns petrol treatments are similar to most other brands and contain various solvents, if your injectors truly are gummed up (that's a big IF on modern engines with good Euro fuels) then the solvents would definitely clean things if used neat, but once diluted in fuel is questionable.
They also contain anti-knock octane boosting ingredients including Naptha which temporarily raise the octane rating of the fuel, this will give sharper pick-up and a couple of ponies whilst it lasts giving the impression the clean has worked.
These cleaners are frequently blamed for damaging fuel pumps so are not advised for long-term use.
Here's some Geeky data on some brands, if you want to know whats in any chemical 'stuff' google the product name and "MSDS" (Material Data Safety Sheet)
