i've just moved into a new home with a parquet floor in the kitchen. its yucky to say the least, dark brown in patchs and dirty looking. some one suggested it is a build up of polish or wax. can anyone suggest how i get rid of the build up and restore it to its original loveliness. do i have to sand it back, can i just use meths to strip it or are there other ways, i don't want to damage it or make it worse than it is!
