If you have one of those express wet & dry floor mops that use replaceable wipes, don't buy the expensive refill packs, just buy thick cheap babywipes. They do just as good a job, are cheaper & smell nicer too!
Use babywipes to clean your tv,computer and some wooden shelves its grabs all the dirt and the dust sticks to it,and it doesnt just spread the dust..you'll be amazed! also use toilet tissue to then dry the wet bits off.
babywipes also work wonders on some leathers,keyboards,futon matress's,computer screens,nicotine stains.
