Rain-X actually cause your wipers to "jutter" when you stop using it.
You can try cleaning your wipers with car wash when you wash your car.
Works for me, wipers is 3 years old and going strong. :bsmilie:
for me, all these 'car care' stuff are not worth it. not that I don't care about my car but i really don't see any problem without using them in the first place. even for car wash, I just use tap water. no soap or anything. just wash, wax sometimes. good enough for me.
RainX is a silicone compound solution. It will only help in the short run since silicone will wear off quite easily. Personally from my experience, dont use.
Usually a good wiper will easily last around 3 - 4 years with proper and simple care. Usually if your wipers come originally along with your car, they are of better quality, especially if yours are the Benz, BMW, Lexus, etc....
A common wiper sets from a hardware store cost below $15 but those from the original suppliers usually cost at least $150 for a pair. I guess the difference is the quality of the rubber as well as the mechanisms and branding.
How do you care for your wipers?
1. wipe away the dust and residues regularly with a wet cloth,
2. if the car is always in the hot sun, separate the rubber from the hot windscreen,
3. always add in windscreen "soapy" solution to the container and do the cleaning when driving along the highway, preferring at speed above 80kmh
4. buy better quality wiperblades.
Though a majority of antifreezes and rain repellents are relatively harmless, there are several products (which may or may not include Rain-X) in the market that are extremely hazardous and toxic, so please read and adhere strictly to the label instructions and when in doubt, kindly refer to their relevant Material Safety Data Sheet (MSDS).
The reason that I had mentioned this is due to the fact that some of the rain repellents (specifically "RainBoe" which contains CFC-113 OKA Freon 113) previously used on-board commercial aircrafts had been known to cause irreversible and permanent neurological damages to the central nervous system of flight deck crews with prolonged exposure.
