Here is a piece of white silicone rubber which is covered in oil and grime
I’ve rubbed half of it with a cloth dipped in 99.9% pure Isopropyl
I do have other chemicals which would be more effective but they could damage the rubber, you can get this IPA from eBay.. the one I’m using is from jemchem.
I would scrub with hot soapy water afterwards rather than leaving the alcohol on your tyres.

Well, I’ve not tried this on a set of porcs but I did have some success on some vintage “NOS” white road tyres that had storage marks so I don’t see why this shouldn’t work.
Step 1, locally bleach the the stain for 10 minutes, make sure it’s clear or white household bleach not blue dyed toilet bleach or they’ll be shagged!
Step 2, take them into the shower with you and use a nail/scrubbing/washing up stuff brush and a general purpose bathroom cleaner with mild bleach in and scrub them then rinse them thoroughly.
Step 3, bake them to rejuvenate the rubber. If you do it properly they will look like new

NOS tyres
Having recently seen some NOS tyres both in the FS section and elsewhere on the interweb for sale with descriptions such as "Still has factory wax coating" or "Still has white mould release agent" et cetera, that, I'm afraid to tell you, this is factually incorrect. When a tyre is new, it won't...

As Betsy has suggested isopropyl.....I used to do injection rubber moulding.....white was feared.....any staining ruined mouldings so we'd use isopropyl to clean the fresh milled uncured rubber before moulding. It evaporates so quickly that's how it's lifts dirt. Use clean plain cotton...as lint free as poss.
Then when they're clean get rid of them before they get dirty again

Most of them are just extensions/variations of the retr0brite project

I've got some other stuff at work known as an advanced Isopropyl, it's made by Gard chemicals and called DEV-103, it's basically an alcohol based dry cleaning fluid designed for use in those spotting machines, they blast it through a garment as a vapour at high pressure to lift the stains and as you say..it evapourates instantly taking the stain with it.
As a liquid in a container it's room temp but put some on a cloth exposing it to the air and it instantly becomes zero degrees, you can only handle it with thick rubber gloves for a few seconds like liquid nitrogen.. put the cloth down and it frosts over with ice crystals.. weird shit but it's an amazing degreaser, non flamable too..

What a great read for a retro community. Top work to those chemists and all those who were willing to partake to help perfect things.
