How to clean NOS tires?

[VintageCat]

Search function failed me here... anyone know of a simple way to get the gray/white crud off the tires in the attached photo? They're brand new, came with an early 7001 kit that was partially assembled but never finished - they've been sitting in the box since it was purchased. Not sure if it's the original mold release coating or what, but I'd like the tires to be the proper black color without the raised crud. Suggestions are welcome, trying to avoid sandpaper or the Dremel.

I have always had good luck with scrub brush, warm water and dish soap.

Spray nine worked on some crawler tires i have.

Thats the only method I've ever used to clean tires before. Heck, thats pretty much the only method I use to clean anything R/C.

I thought you can put them in an oven and bake them?

Left out that my original attempts were with Simple Green and a scrub brush... it took a minimal amount off, what you see in the pic is the 'after' photo from those attempts. Dish soap I have not tried, is there any specific (chemical) reason behind using that? Thanks for the help, everyone.

Yea just give them a good scrub with soap and warm water. If you want to give them a nice deep black shine I have used Maguire’s tire shine, it helps hide the white residue. You can basically use any rubber conditioner. I have heard rubbing baby oil works also.

I use a basic Dawn dishwashing soap and scrub brush. The dawn works great on grease and such and not so bad here. Don't know if there are any chemicals in it that make it easier but like lowgear said...its about the only thing I use on R/C stuff too besides an air compressor.
