I have been making all of my own cleaning supplies. I needed a windshield de-icer and found these recipes. Making your own is much more economical and it will ease the task of removing ice from the windshield. Recipes include: a de-icer, ice and frost preventive spray, and a recipe to keep the lines free from ice. The bottles are simulated to show pictures of the different products. I am not an expert, doctor, chemist, or a professional in any occupation. I share here how I interpret it to the best of my knowledge. Use these applications at your own risk and own choice. Keep all products out of the reach of anyone or anything that could be at risk of injury.
