Slippery ice on sidewalks and driveways is a serious hazard—but not all de-icing methods are created equal. Some can damage concrete, harm pets, or pollute local waterways. The good news? With the right approach, you can keep walkways safe without unintended consequences.
Here’s how to de-ice wisely this winter.
❄️ Step 1: Shovel First—Before Ice Forms
Why: Removing snow before it compacts and freezes reduces the need for chemicals.
Tip: Use a plastic or rubber-edged shovel to avoid scratching surfaces.
Best time: Shovel while snow is fresh—don’t wait for it to melt and refreeze into ice.
🧂 Step 2: Choose the Right De-Icer (Not All Salt Is Equal)

Less effective, can irritateWipe paws after walks—de-icers can cause chemical burns or poisoning if licked.
Avoid rock salt near lawns or gardens—it leaches into soil and harms plants.
Never use fertilizer as de-icer—high nitrogen content pollutes waterways.
🏠 Step 4: Prevent Concrete Damage
New concrete (<1 year old) is especially vulnerable—salt causes spalling (surface flaking).
Use sand or non-clumping kitty litter for traction instead of salt on new driveways.
Seal concrete in fall to reduce water absorption (less freeze-thaw damage).
