does anyone have a good solution for keeping a 100 foot cord untangled while in storage?

Answer 1

Wind it around a hose reel. Or get one of the reels made for electric cords if you want to spend a little. They have hanging hooks already on them, just hook 'em on the wall after you've wound up the cord.

Answer 2

Wind it around an object and make sure the end is clearly visible or have a knot at the end. This will help in easy unwinding.

Answer 3

there are lots of ways to do this try using wire ties (zip ties) they are cheap and hand to have for verious reasons there are also different ways to roll cord but the easiest is to use wire ties
