recently bought a 2nd hand car, my problem lies here, every raining day, my newly change silicon wiper juddering like mad (suspecting previous owner put rainX inside the wiper water container), is there any way to clear out & smoothen the wiper wiping on my windshield? fren told mi drain out the water refill clean water or even put mama lemon wont help coz he done it b4. anyone here got this issue b4 & manage to get rid of it. arigato

hi all, somehow after awhile say 5 to 10 mins of wiper activation, the wipers begin to judder. has anyone face this situation and managed to find a solution to DIY to solve it or must we send it to our authorise dealers? Thanks

last week changed the wipers (BOSCH whole set). Its juddering. Infact the shop guy identified the correct length and changed it. Does it need any time to season it? Any idea? worst case I need to go back to him..

Hi all My wipers have been juddering very badly whenever i turn it on. The wipers are new (new ride collected about 3 wks ago) and it was fine and it happened about a week ago. Spoke to some friends and they mentioned to wipe away the dust from the wiper blade and also clean the windscreen with glass cleaner (the type of blue solution we use to wipe our windows at home). Have done it but still no use. Any kind bros/sis out there can give advice? Many thks!!

OK this going to be a long report but please bear with me. I collected my Aveo in May. The car is great except for the windshield wipers juddering. Mama Lemon, Jif, and all sorts of aggressive stuff doesn't solve the problem. I guess it must be some stuff the dealer put in my wiper wash but I was wrong. It seems like Starsauto has RainX'd the glass. I got fed up and so called up a helpful guy whose contact was given by Protege in this forum. I bought some of the stuff from him and he even polished my windshield with the stuff. The windshield now wets very well. With water cascading down instead of beading up. He revealed to me the stuff he is using contains cerium oxide (CeO). He said he got a hard time finding this stuff. My search on CeO reveals that it is widely used in the glass and gemstone industry where it is used for polishing. CeO works very well on anything that is silicon dioxide based as in glass or quartz. There are many grades of CeO. There is 99.9% pure stuff which is a white powder and there is optical grade which is around 80-90% cerium oxide and the rest made of iron, aluminium and other rare earth oxides. The mechanical action of CeO is very fast as he demonstrated it. He just made a slurry of the CeO powder with water and dabbed the sponge with a 3M green scourer pad on it and just started wiping the windshield with the slurry. The glass was smooth in an instant! Basically if I recall my chemistry correctly, glass polishing is basically glass removal and does show a dependence on chemical properties of the glass. The nature of the liquid present during polishing is crucial and only if active hydroxyl groups (OH-) are present, in alcohols for example but especially in water, does the polishing phenomenon happen. When a glass-typically an alkali silicate-is in contact with water, a complicated series of steps take place: ion exchange, dissolution of glass constituents and possible structural changes. A surface region of the glass is modified and it is this softer hydrated layer that is removed or reformed during glass polishing. The reason why glass beads water is because the surface of the glass has been altered with the silanes present in RainX. It is not a coating! RainX modifies the glass surface chemistry. It does not add a layer of silicone on the glass. This is not wax you are looking into. If it is wax, Mama Lemon or any detergent will remove it. As said above, the nature of the liquid used in polishing is crucial. This theory says that the best additive is ethanol. Reducing surface tension reduces the surface-to-surface drag which eliminates chatter, resulting in a smoother surface. The surface tension of water is 73 dynes/cm and ethanol is 22.3 dynes/cm. I have not tried this yet but will do soon if I got the chance. So anyone here has some contacts with people in the glass industry? People in the crystalware industry should have CeO as well.

Check link below: http://www.mycarforum.com/...i?post=618475#618475 I believe many of the Aveos and Optras should be experiencing this. Please note that some of you might want to keep the beading water surface. This is not something for everyone. If you are not the high speed driver type and juddering wipers irritate you, this is THE solution for you.

See this article from Popular Mechanics: http://www.popularmechanics.com/automotive...at/1789177.html Twist your wiper arms until the blade sits perpendicular in mid-sweep. Not for the faint hearted!

Anyone of you experience this? I notice that the water beads on the front windshield. The wipers are smooth initially and then as the rain goes on, the wipers judder like hell! Never put any RainX or silane on the front. But I do suspect the wiper wash has something like it. I don't use wax as well.
