You might want to take a look at Armstrong's line of vinyl floor products. They have products to strip your floor, a good cleaner (Once 'n Done) and also a couple of options for restoring the shine (either a low gloss or high gloss) specifically designed for no-wax floors. I'll link the page below.

I have used the stripper (only a few times) and was satisfied w/ it. I regularly use the ONce 'n Done for my vinyl flooring and I really like it. I have also used the shine restorer, but I don't remember which one. Whichever one it was, I liked it :-)

Good luck!

Oh, and I've purchased these products from Lowe's and other stores like that.
