How to Prepare Car Film Solution?
2 Answers
Pure water mixed with dish soap or shower gel. Generally, add 5 drops to 200 milliliters of water. If the film doesn't slide well after application, you can add a bit more. Typically, add 5 to 6 drops of dish soap to a bottle of cold water, shake it well to mix, then adjust it to a spray form. Finally, spray it onto the glass until bubbles appear.
I've been applying car films for over a decade, and the preparation of film application solution is crucial. The optimal formula is distilled water mixed with neutral detergent—I recommend baby shampoo as it contains no additives that could damage the adhesive. The typical ratio is 3-4 drops of shampoo per gallon of distilled water, mixed uniformly at around 20°C. Avoid using tap water, as mineral deposits can leave stains. After preparation, pour the solution into a spray bottle. When applying, lightly mist both the glass and the film backing to allow smooth sliding and positioning. The spray amount should be moderate—too much prevents adhesion, while too little causes sticking. I always prepare fresh solution for each job, as stored mixtures can deteriorate. This formula gives beginners high success rates—just ensure proper ventilation during application, safety first. Keeping large bottles of distilled water on hand is convenient for daily use.
