have not tried it on sponge, but rubber renew, or lacquer thinner

They look the the donuts you could get through BSRT/Scale Auto years ago.
The outer cover used to get hard on them,but it would cut off when truing them.
But that was when the donuts were only a few years old,those babies look well aged.
Have you tried truing one to see if it's still semi-soft under the outer envelope
