How to Make Anti-Fog Spray?
4 Answers
Mix household dishwashing liquid and water in a ratio of 1:10. After mixing, use a towel to dip into the solution and evenly apply it on the car glass, then wait for it to air dry naturally. After wiping off all traces on the glass with a clean towel, a thin film will form on the glass surface, effectively blocking moisture and providing an anti-fog effect.
Last winter, my car windows kept fogging up, so I made my own anti-fog spray that worked really well. The materials are simple: buy some isopropyl alcohol or regular rubbing alcohol from the pharmacy, mix it with distilled water—9 parts water to 1 part alcohol—and pour the mixture into a small spray bottle. Before use, shake it well, spray it onto a soft cloth, and gently wipe it on the inside of the windshield. The alcohol evaporates quickly without leaving streaks, and the anti-fog effect lasts for several days. The best part is it saves money—a bottle costs just a few yuan, much cheaper than store-bought versions. I also tried adding a drop of dish soap to enhance the effect, but don’t overdo it to avoid making the surface slippery. Store it in a cool place, and keep it away from heat sources since alcohol is flammable. This DIY spray also works on glasses or bathroom mirrors—super versatile and convenient.
As someone who frequently works on car repairs, I must emphasize the safety concerns of homemade spray solutions. The method is simple: just mix alcohol and water in a 9:1 ratio, but don't casually substitute household cleaners as they contain chemicals that may corrode window coatings. Always test on a small area before full application to avoid widespread damage. Exercise caution during operation—use clean containers when mixing, and ensure proper ventilation after spraying to prevent respiratory irritation from alcohol fumes. Safety comes first—alcohol is flammable and explosive, so store it away from the car engine or direct sunlight. I've witnessed incidents where leaking spray bottles nearly caused fires, making protective measures crucial. In terms of effectiveness, it works well for anti-fogging, ideal for winter mornings before driving, and helps save money too.
I found that homemade anti-fog spray is super cost-effective and eco-friendly! Just mix regular alcohol and distilled water in a 1:9 ratio, with costs so low they're almost negligible. The alcohol quickly evaporates and adjusts surface tension to prevent glass from fogging up, with effects similar to store-bought products. From an environmental perspective, there's no packaging waste, and it reduces pollution from chemical additives. I take pride in using it myself, saving money that can be spent elsewhere; it's convenient for driving in winter or checking the mirror after a shower. Just one caution: avoid using alcohol that's too concentrated as it's flammable, but with proper ratio control, it's safe. This DIY method is simple and efficient, and I encourage everyone to try it to cut down on expenses.
