Marmoleum genuine cleaner works best
I love my marmoleum floor and have found the Forbo cleaner does a great job and keeps the floors looking like new.  Even if you don't put the shine product on the floors stay looking good.  My only complaint is that because of where the seller is the shipping was expensive.  But we have had the floors for many years and are only on our second bottle so it is not that big a deal.
