Rainex vs potato?

[RubyBlueZ4MC]

So I went to get my car washed today ( ) with my dad as we do sometimes, father-daughter bonding type thing...and I mentioned wanting to buy Rainex for my rear windscreen as a few of you have mentioned it. Then he started talking about cutting a potato in half and rubbing it over my windscreen to do the same job for less cash..what is he on about??

He'll mean the starch in the potato but I can't see how that would work. He might be pulling your leg :wink:

Rainex works a treat.

 

[Maniac]

Lord knows, probably something to do with the starch and its preventing beading etc...

I have rainX but haven't applied it yet, waiting for summer so I can polish some scratches out with cerium oxide and my DA and then I'll apply it.

 

[KERMIT1970]

Have heard about that before. It's the starch that makes the water bead.rain x works great.

Was he Irish? :lol:
Potato!

Ive used rainx for years on the front screen & side windows , problem is for it to work the speed of the car / oncoming wind is what blows the rain off :wink: have tried it on the coupe rear window but its no different to any other glass cleaner or polish :|
Don't expect miracles Ruby :roll: in fact . why not try doing half the window & see what you think ?

I'm very curious and may have to try the potato thing tonight

Perfect experiment . half with the spud , half rainx & pics in the rain please :wink:

Rain-X is useless when it comes to grimy road-film/spray as the water is blown off but the muck stays. So you end up using your washers/wipers anyway.

Below 40mph it doesn't work very well, but 100mph plus at night in torrential rain and you can leave your wipers off

We don't want to see a post in the morning that you are in A&E with a potato stuck in your eyes oke:

I'll wear the lab glasses my dad got me when he also supplied me with squirty de-icer instead of the spray one after I told him what happened that time. Rest assured pvr.
