I'm almost ready to put the windscreen of my Citroen DS back in after thorough rustauration on the (amongst others) roofrail. The old rubbers are not that bad that I want to replace them right away, but they could be better.
Now I know that there are products available to rejuvenate them somewhat, but of course they're not available here and I think most of them are snake oil anyway. I also heard that you should put them in the washing machine at 60 degrees with a phosphate based washing detergent.
So now for the questions; does anybody have experience with this, what are phosphate based washing detergents and why should they work? And if the washing machine is not the way forward, what is?
regards, Joost

I use Autoglym vinyl and rubber care. Soak the rubber in it over night and then just clean off.

I am also interested to hear what others have had success with.
I would guess if they are on OK condition some sort of 'feed' might be appropriate. On the other hand if they are starting to crack then something with 'filler' properties too will be required?
Several (about 5) years ago I flicked through an issue of PPC in an office waiting room and they had an article/advert on a product that was like 'paint on rubber' to fill and 'weld' the cracks back together but I have never managed to track it down since, I'm starting to believe I dreamt it!
Like I say interesting topic.

So I went ahead and put the lot in the washing machine with a dishwasher tablet (which turns out to be high in phosphate) with an old overall to use as a bit of dampening.
They're very clean, which is nice, but not entirely what I wanted.
I'll have a look if I can find any autoglym here.

Like I say interesting topic. -Steve- Devcon has a product which is used to repair rubber conveyer belts, I contacted them once and while it's not very petrol or oil resistant, it would be very successful in repairing rubber (window) seals. I also found this thread about carburetor boots on motorcycles, which might work, but I would need a lot of fluids to completely submerse my windscreen seals. And also I have no idea what "winter green oil" translates to in Dutch... linklink2link3

the autoglym is only a dressing , i don't think it will do as you want only leaves a greasy film so it looks new until it rains

I just clean them in a bucket of soapy water (get Dusty from the Wibra!) and to finish them, dry them then put some of the foamy tyre black (from a spray can, W5 from the Lidl) and give them a good polish.
Succes ermee!

One of the best rubber restorers in my opinion.

And also I have no idea what "winter green oil" translates to in Dutch... Grip tyre softener used to be made with Wintergreen, it's still available here in the UK but with a 'new' formula, so no idea what's in it now. Still, if it softens rubber it may do the trick on the seals. Grip Tyre Softener
