Query: Best wood floor cleaner I've ever used

I have tried dozens of cleaners and this is the only one that really leaves a nice long lasting shine on my old beat up wood floors. It works best if you use a large amount of product (it takes longer to dry when you do this but the result is really worth the wait). The shine will last for 2 - 4 weeks. I just wish this product was availabe in local stores as ordering it and paying postage is bothersome.
