Yes, tyres. We're talking New Zealand here.
Last month's misadventure with bad alignment practically ruined a front tyre before I realized what was happening.
So last week when I saw new front tyres on sale at a fabulous price I ordered one. It arrived yesterday.
Like the previous tyres, it's NOS from New Zealand. But unlike the others, it has some green stuff all over it. This view shows the side I haven't tried to clean yet.
I began my cleaning attempts on the worse side. Like Edison, I was very successful in finding what didn't work. The agents which had little or no effect included acetone, lacquer thinner, window cleaner, petrol, and charcoal starter. I phoned Lucas and was told soap and warm water would remove the stuff. I tried dish detergent, shower cleaner, and Boraxo. A combination of those did a little good. Bleche Wite did a little more, but certainly didn't get all the stuff off.
Here's a closer look at the unwashed side of the tyre.
This is the "clean" side. Some of the green stuff is so stubborn that thus far it's refused to go away.
This is also on the washed side. Not good enough.
Has anybody else run into this problem? Did you find a solution?
When I would do the white walls on the former wifes car, I always used Comet and stiff hand brush. On my T's back tires that were browning used the same and followed with a non-gloss tire dressing.
Obviously a job for Oxy-clean, Steve.
Brakekleen might take it off. You will probably have to put on some type of dressing after as it can dry out rubber. Try a little spot first.
Years ago all the white tires that we sold had that coating. We would just use water and a mild soap with a brush after mounting. If you used a solvent it would be much harder to remove.
Soap and water. It's just a preservation coat. Using other stuff won't work as good as fish soap and a stiff brush. From experience I speak!
Common coating on WW tires. Soap & water + a mild brush. So old it's new. ( to some).
Soap, water, and a scrub brush. Takes a little time.
He's using up and the money he saved on the tire, just to spend it on cleaning products!
Knowing Mister Thrifty, he using what is handy around the farm.
Try soap n water followed with a Brillo pad scrub
Just drive it through the mud a couple of times and you won't have to worry about the green.

Steve, I use spic and span to clean the wide whites on my harley. Worth a try.
SOS pads always got my whitewalls nice and clean no matter what was on them. getting all of the green off around the raised letters might be tough. I suspect that the green stuff is/was the same as the blue stuff used now to protect whitewalls on new tires.
it easily comes off with soap and water on a new tire, but if you leave it on for a while, it dries out and becomes nearly permanent. Your NZ tyre is probably quite old and the green is cured and dry. It wants to stay.
I suspect those of you who removed the stuff with soap and warm water did so when it was relatively fresh. No telling how long it's been on these NOS tyres, and apparently the passage of time makes it more stubborn. Lots of hard scrubbing with Oxi Clean, Comet, Dish Detergent, and Bleche Wite did some good, but the most stubborn deposits refuse to leave. I'll mount the tyre with the better side out and call it good enough.
ATTA boy Steve, that's the spirit !!! Damn the green stuff, full speed ahead. Hope they stretch .
Nothing cleans white tires better than driving in the rain.
Eric...not so! Poor Pete got caught in THREE rain showers, one pretty heavy, last year in one day on a tour! Made no difference. The tires just kept getting browner!
It looks like PVA (poly vinyl alcohol) which is used as a mold parting agent. Warm water and soap always worked for me. I guess if it sits for a few years it will take a little more elbow grease to remove.
I would actually question the NOS from New Zealand statement. Where / who did you buy them from ? Firestone have not made Beaded Edge (clincher) tires here for many years. Did they have a moderately fresh tire smell ?
John is correct ...looks like PVA to me as well ...submerge the tire (tyre) in water for a few days to allow the material to soften ...then it should rinse away with very little effort ...always an optimist...Gene French
I don't know Steve that first tire sure looks "period" correct to me.
Coker tires uses a 'blue protective coating' on their white wall tire final step to protect the white surface.
Purchased Pirelli tires for the truck and the raised outline white letters had blue over them, scrubbed with brush and soapy water and the white letters got white.
I bought the tyre from Lucas.
As I have mentioned in another thread recently, Firestone stopped making 30x 3&1/2 tires here years ago not that I ever recall seeing white tires on the shelves. If made here, I would suggest they are nocking on 50 years old. I believe the moulds ended up in Vietnam ? and I bought a set of black tires some years, came packed with "made in Vietman" stickers on the wrappers and recall showed the Made in NZ still on the sidewalls. They are wrapped and stored away so cannot easily dig out and check.
But certainly not made in NZ for many years.
I'm here and sourced mine thru Chatanooga !
Steve, I doubt that this will do you much good what with all of the other suggestions posted, but back in the '60's-'80's we used Comet cleaner, or another like product, and a BRASS bristle brush to clean any white rubber. Worked great, but of course the "gunk" on them wasn't 50 years old either. The brass bristle brushes did do a lot better job than just any old stiff brush though. Good luck! Dave
The correct answer is....................Steam cleaner!!!!!!!!!!!!!!!! It will clean and brighten the white tyres like new.
On my new set of Firestone W/Ws for my Model A I had some stubborn blue stains from the protectant gunk all over the sidewalls very similar to yours pictured. I got them very clean with careful use of Goof Off (paint spot/spill remover) saturated on a paper towel. Needed to renew the paper towels quite often since once the gunk was lifted off the sidewall, it would easily reattach from the paper towel.
Be careful not to rub harshly with the solvent and be sure to wash off excess residue after cleaning.
Steve, any update? Was the tire shop able to mount the tire?
Going green with a T beats buying a Prius 😊
