Can car oil film agent be added to windshield washer fluid?
2 Answers
Car oil film agent should not be mixed with windshield washer fluid as it may scratch the glass. It should be used according to its instructions. Below are specific details about windshield washer fluid: Concept: Commonly known as car windshield cleaning fluid, it is a consumable in automotive use. High-quality car windshield washer fluid mainly consists of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. Function: When the transparency of the front windshield decreases, spraying windshield washer fluid can provide a clear view. Especially during night driving, dust on the glass can scatter light, necessitating the use of windshield washer fluid to maintain the front windshield in optimal transparency.
I’ve actually thought about this before—after all, everyone wants a quick one-spray solution when washing their car. But in practice, I found that the concentration of the oil film remover is much higher than windshield washer fluid, and mixing them just clogs the nozzles completely. Once, all that came out was foam, and I had to disassemble the spray head to clean it. A knowledgeable friend later explained that the degreasing agents in the oil film remover react with the alcohol solvents in the washer fluid, forming clumps—like coffee mixed with powdered milk. Now, I handle them separately: on sunny days, I apply the oil film remaster to the windshield first, let it sit for five minutes, then wipe off the grime with a sponge in circular motions before refilling with regular washer fluid for daily use. It saves money, hassle, and doesn’t harm the car.
