I've bought products for wiper blades before that are supposed to clean the wipers and stop the chatter. I no longer buy those products. I used to buy alcohol to clean them, but it's always a pain to carry any extrta liquid cleaning product with you. What do you do when you run out? I'll keep rain-x solution in the car, but that's it. Anymore, I simply keep the rain-x wipes. Good for the windshield, but not so good to wipe the blades with.
This if for cleaning on the go...it's never failed me as long as you have a quality wiper in the first place. I run Bosch, or Michelin wipers. I've also ran autozone winter blades for 1 1/2 yrs straight on my old truck that performed flawlessly provided I kept them clean.
I simply pull into the gas station to fill up. Then decide to clean my windows from the window cleaning box at the station. I grab some blue window cleaning towels and soak them with the fluid from the box. I then rub the blades of the wipers with this fluid (if fluid isn't real clean go to the next station) until there is no black gunk appearing on the paper anymore. Once the paper wipes clean you're good to go for at least 2-3 months. I used to not clean them again for this time period, but that habit it to clean them at every gas stop now.
I've gotten so used to doing this that I give the wipers a wipe every time I pull into a station now. Since I've built up to this habit I never have wiper blade issues anymore. Sure, I keep rain-x in the car, but sometimes I don't take time to apply it.
I will try aquapel soon, but there can be times when this stuff will wain and you need your wipers to work without a hitch.
Here's my advice for what it's worth.
I'd follow a regimine very similar to BobbyG's 3-steps he provided for you. Good solid advise. I do a similar version.
The only thing I do different is I continue to wipe my blades clean at every filling station stop. It's a habit now. I know with the rain-x, which I now use more often (or aquapel if you have it), and the habit of cleaning my blades every time I stop, I know I'll always have protection from rain...and won't have to worry about wiper chatter should I need to use the wipers. Just wipe them clean with the blue papers from the station and their cleaning fluid. Remember, just wipe them until you see no more black on the paper. You pay enough for gas, so use their fluid and save your money for other detailing products.
