hi paul, 
if you can get your hands on an airflo with a hoover attached, you will have a cracking finish,  have a lookat my website and tell me if they are as bad as those,  they would need sanding if they were,
anyway use the airflo with a scotch mesh,  grit 60, then hoover the floor from the fine dust,  then apply a good varnish maybe for a domestic put three coats of ronseal varnish you can get it at b&q, or hss,  you will get a lovely finish,
if it just needs polishing use a good detergent maybe taski energy then let it dry then aply carefree emulsion polish about two coats should be ok
thanx and good luck jonny
let castle take the hassle
