The cleaner Sachs has found on Ebay (Hagesan Laminate Floor Wash & Shine) - its useless - I bought some from Ebay tried it on my laminate floor - it left dull marks and had no shine. In fact as soon as I added some to water in the bucket it had the tell tale blue colour of optical brightners.
I resold my bottle on Ebay the following week.
If you do find a product that makes it shine Connemmara, it will have the optical brightners in it and they eventually leave a film over the floor. I used this type of product on a stone tiled floor in my porch - over a period of time a film built up and had to steam clean it off.
I use the Pledge Soapy Cleaner.
