i use master wraps (thin light blue)..I wrap fat end to tapper end of wrap ending at outside handle end and I wrap so there are "extra" wraps in the dip that are not seen on the surface...when the wrap gets nasty, I take it and wrap going taper to fat end and I get a near brand new wrap
when this gets nasty, I unwrap and do the same routine with the back side...it isn't quite as sticky as the front but after flipping from a nasty front side, it is like having a brand new wrap
if you want to extend the life of each of these cycles, you can take a wet wash cloth while the wrap is still on the handle and scrub like hell and get 90% of the dirt off and "refurb" them
this way you can have good to brand new wraps at home for many months on one wrap
now I handle (excuse the pun) wraps at a tournament a little differently...I don't let them get nearly as dirty before flipping and I don't wash cloth scrub them
my hands sweat more at tournaments then at home so I am flipping them more often to keep giving me a drier side...i have recently started using the rousin from this site and that has helped a lot for sweating but it isn't so hot on how long the wrap stays "fresh"
I like my wraps newer but have learned to live with them less than I prefer because I can't pay for my preference....however, everyone is different...I know people who will use the same wrap for like a year...not my cup of tea but to each their own
you will need to experiment and find what you like best...good luck
