White grease problem on Clod tyres

[Buggyjam]

My Clod tyres seem covered in a white grease, it's quite sticky. The whole tyre looks chalky. I tried cleaning it off with fairy liquid but no joy. It actually seems to come out of the rubber itself so I'm not convinced it's mouldy release agent rather something sweating from the rubber. Have you found this? Any ideas how to get rid of it? The colour doesn't bother me so much as the stickiness.

Really hot water (50% boiling), fairly liquid, leave to soak then scrub with a brush, hard. 

Or something like fenwicks bike cleaner.

Cheers Prescient. Pretty much tried the first one but water was dishwater hot so I'll up the temp use a brush.

 

 Was cautious about anything solvent as didn't want to dry out the tyres? Don't know if this is a valid concern or not really.

Fenwicks cleaner is fine same as muck off etc as doesn't hurt cycle parts or tyres.

Was it a new kit? Should clean up unless someone has used spray lube on the tyres or left in a chloride based chemical which caused it.

Yeah it's a new kit. A lot of people don't seem to have this but I also read someone noticed it after they'd left their stock tyres unused in a box for a few years so perhaps the kit has been sitting a while in stock.

 

i finally got 95 percent off using the very hot water. As my misses is always saying, I wasn't scrubbing hard enough

Just run the truck. Then all you'll see on the tires will be dirt and dust.

I posted the following response in another tread. If you are dealing with a recent kit there is a possibility that the white haze is actually mold release used to get the tires to come out of the mold. If the kit is a few years old then you are more than likley dealing with "BLOOM".

See below.

"This is referred to as "bloom" in the rubber industry. Over time the plasticizers in the rubber begin to creep out and cause a white film on the surface.   While I have no clue what the these RC tires are made from, we always handled the issues the same way regardless of compound by applying heat. This causes the compound to soften and reabsorb the plasticizers. The way we handled it was by placing the o-rings and gaskets in large mesh bags and tumbling them in an industrial dryer for a few minutes.  I don't recommend that you do this at home as it causes a fair bit of stink and will get you divorced in quick order. 

For RC tires I've had good luck with a normal hair dryer set on Hot. Different compounds soften at different temps so you might have to get the tires pretty darn warm.  Afterwards I would wash the tires with simply green and a tooth brush in very hot water to get any remaining grime off of them"

Thanks racer. I actually scrubbed it off in the end. Hopefully it wasn't oil that was needed back in the rubber. I'll know when they go all hard in a couple of years ha.

The bloom isn't really olds so much as it is waxes. The tires will be fine.
