How to Wash Waterproof Blanket: Essential Care Tips

How to Wash Waterproof Blanket: Essential Care Tips

Waterproof blankets are invaluable for outdoor activities, pet care, and as protective covers around the home. However, their waterproof qualities require specific care to maintain. This guide will provide you with detailed instructions on how to wash your waterproof blanket effectively, ensuring it continues to perform at its best.

How to Wash a Waterproof Blanket

Waterproof blankets are designed to resist water and protect underlying surfaces, making them perfect for outdoor use, pet covers, or protecting furniture. However, washing them requires careful handling to maintain their protective qualities. Here’s how you can clean your waterproof blanket effectively:

Materials Needed

Washing Instructions

  1. Preparation:

    • Shake Off Loose Debris: Start by shaking the blanket to remove any loose soil, leaves, or debris. This helps prevent dirt from getting trapped in the washing machine.
  2. Spot Cleaning:

    • Address Stains Immediately: If there are visible stains on the blanket, spot clean them using a mild detergent and a soft cloth. Apply the detergent solution to the stain and gently dab, don’t rub, as this might spread the stain or damage the waterproof coating.
  3. Machine Washing:

    • Setting the Washer: Place the blanket in the washing machine and set it to a gentle cycle using cold water. Cold water is essential as hot water can compromise the integrity of the waterproofing material.
    • Detergent: Use a gentle, non-bio detergent to avoid damaging the fabric or its waterproof coating. Do not use bleach or fabric softeners, as these can degrade the waterproof materials.
    • Load Size: Ensure not to overload the washer, as the blanket needs space to move freely during the wash cycle.
  4. Rinsing:

    • Rinse Thoroughly: Make sure the blanket is thoroughly rinsed with cold water to remove all detergent residue, which can leave a film that reduces the fabric’s waterproofing abilities.
  5. Drying:

    • Air Dry Only: Hang the blanket in a well-ventilated area to air dry. Avoid using heat or tumble dryers, as high temperatures can melt or damage the waterproof coating.
    • Do Not Wring Out: Squeeze out excess water gently without wringing, which can crack or peel the waterproof layer.

Additional Care Tips

To ensure your waterproof blanket continues to function effectively, regular maintenance and proper storage are key. Here are some additional tips to help you maintain its waterproof integrity:

  1. Avoid Harsh Chemicals:

    • Chemical Exposure: Keep the blanket away from harsh chemicals, including solvents and bleach, which can break down the waterproof barrier over time.
  2. Proper Storage:

    • Dry Before Storing: Always ensure the blanket is completely dry before storing it to prevent mold and mildew growth.
    • Storage Location: Store the blanket in a cool, dry place. If space allows, hang it instead of folding to avoid creases that could stress and break the waterproof fabric.
  3. Regular Inspections:

    • Check for Damage: Periodically inspect the blanket for any signs of wear or damage. Look for peeling, flaking, or cracks in the waterproof layer. Early detection can help you perform minor repairs before they become major issues.
  4. Gentle Handling:

    • Avoid Rough Surfaces: When using the blanket, try to avoid placing it on rough surfaces that could puncture or tear the fabric.
  5. Refresh Waterproofing:

    • Reapply Waterproofing Treatments: Over time and after numerous washes, you might need to reapply waterproofing treatments. Products such as spray-on or wash-in water repellents can restore the fabric’s water-resistant properties.
