Is cow saliva corrosive? - Glaikit Wee Scunner {P}
Was stationary in a herd of Fresians a few weeks back. End of Old Coal Pit lane (A5270) near Buxton. The usual gentle jostling and occasionally worried that an elderly cow was going to end up on the bonnet. A few beasts licked the car and now am amazed that it seems to have damaged the paintwork. Washing,T cut and polish have not shifted it.
Watch out!

Good Lord! If it damages paintwork so badly then how come cows don't leak? Seriously, that's more than a bit of bad luck. Perhaps these mobile paint repair chaps can do something?

I doubt whether cow's saliva is corrosive but a cow's tongue is rather abrasive and I suspect this is the cause of the damage.

When I set to washing the car yesterday , definitely looked like a dried on slather of saliva.
Guess their tongues have to be pretty tough the way they munch through things.

You're lucky it wasn't something to do with the other end!

More information on the cow.
The saliva of the cow contains Bicarbonate which is alkaline, not corrosive but maybe not good for paint if left too long in contact with it.
The cow has a lack of upper incisors and relies on an upper gum pad to provide some of its grinding surface for the lower incisors. The abrasive tongue also helps in this process.
I conclude that your paint damage is a combination of abrasion and mild alkaline attack.

I have known several Cows over the years that have had abrasive tongues!

My lot had the corrosive saliva too but now I am free!
Seriously though, there has been mention on the forum of something called 'clay bar?' for dealing with paint problems. A forum search may give some clues.

Never mind your car, what about the poor cow with your paint in its' digestive system!

I could be drinking that in my tea (now I know how to make one thanks to IHAQ).

Don't know about saliva (we call it spit here on Merseyside!!) but back in the early 80's my dear old dad bought a new Escort Ghia in Champagne Gold metallic paint. About a month into his ownership he was involved in a meeting with a herd of cows on a country lane and one of the beasts rubbed along the rear offside panel. Later inspection revealed that the panel was devoid of the protective lacquer that covered the paintwork and it stayed like that for the ensuing 23 years that he owned the car with no further deterioration!

Doctor Chris is correct about the abrasive tongue damaging paint.

I had this happen to my Dad's Wolseley 16/60 (PMB 242H) while I had the use of it for an afternoon nearly 40 years ago - it wasn't a pleasant experience explaining what had happened..

There was salt spray dried on the sides of the car, and the cows helped themselves while it was parked.

As memory serves, I couldn't get the marks out with polish, but a garage did with something (Belaco rubbing compound?).

Bear in mind this car had cellulose paint, and it was a bit thin in parts after the treatment.
What you'd do with a modern lacquer top coat I couldn't say - it might even turn into an insurance job.

Don't know about cow saliva but there is a brand new MB tin-top convertible at work - Has been covered in pigeon poo for the last month........Does she know the effect this will have, I wonder?

>>Has been covered in pigeon poo for the last month...

Our departed Skoda Felicia (metallic silver) was sadly ignored under trees for many years towards the end of its life, and the pigeon poo made no impression on the paintwork at all, despite being left on it for months at a time.

I suspect the lacquer top coat isn't bothered by ammonia, or whatever the ingredient is that can damage paintwork.

Daughter had an old Volvo 340 that was parked under trees most evenings, with roosting birds above. Once a month she'd take it to local 'wash by hand' place that threatened to charge her extra.

It looked like the dark grey bodywork had a much lighter primer underneath, in many places.

I now always clean the guano as soon as I notice it!

Edit: For the pedants. Guano seems to refer to sea bird excrement only. I was being less descriminative.

See Bird. Is that Sue back again? She took me to the Cleaner's last time!
