cleaning windshield washer bottle

Considering it was a gloried milk jug originally, I wouldn't hold out much hope. If your to do list is that short, BlackDragonAuto has a universal windshield washer kit that looks identical to my series I unit for $20. At that price, there's no reason to let smashed bug win.

On a somewhat related note, does anyone know of a source for motors that will fit on the windshield water bottle? The one on mine is corroded solid. I had a spare tank from a roadster but the motor on that one is in the same condition.

Trico 11-601

That's a pretty big jar you'll need to immerse the entire washer reservoir- probably a two-gallon one. I suppose you could just do one side at a time? I saw a short YouTube video on this, and the person left the plastic part only party-immersed in the solution, and could see the line where the liquid was.

I wonder if Meguiar's or some company like that has a product to clear up the UHMW plastics.

I think dry walnut shells would do a better job than coffee grounds in water. The idea with that is to slightly smooth or polish the inside surface. You could make the plastic "clear" by just filling it water, but as soon as it dries, it will show the aging again.

I am also a member on the Meguiar's website, so I posted this question, hoping one of their experts could recommend something. I did get a reply from a "detailing expert" who simply just says that you can't polish it like a headlight lens, so "just buy a new one." I wasn't aware the coolant reservoir was relate to the headlight lens.

40-year-old new plastic bottles?

I looked into this some and did some thinking about the thing too. Basically what you have is an oxidized plastic surface; sort of like rusted metal. By using the peroxide & oxy mixture, you are basically removing the layer of oxidized plastic, and that makes the thickness of the reservoir wall thinner. Sure it might look like new, but what do you do the next time it starts to look milky or opaque? You use more of the solution to 'melt off' the oxidized stuff, and the plastic gets thinner yet. Eventually you will have holes in it.

So what you really need is a way to convert the stuff on the inside surface back to a transparent or translucent plastic- essentially restoring it to a like-new condition. Either a restoration product or a transparent coating is needed here, not an "acid." But without knowing exactly what kind of plastic it is, you are probably doing it more harm than good. Even my polymer Chemist friends can't suggest anything but to 'polish off' the stuff to get back to the original plastic.

Banzai Motorsports just have reproduction motors made and sells them for $25.50 I believe. I just received mine and it is just as original.

Give mike a call or check out his web site.
