MinnMan At the old job I parked in a part of the warehouse where leaving a puddle was not an issue.
At the new job I put down a 6x2 foot synthetic rug...under $20 at Wal-Mart. No muss and no smell last winter. So far so good this winter...but to be fair, it's very dry here in Colorado Springs.
I remember reading here years ago about an apartment-dweller who used a plastic mat with a lip to contain the melted water.
