Has anyone been able to take a leather strop pasted with diamond paste and clean it out enough to use as a non-abrasive stropping surface?

I have a Tony Miller paddle that was pasted with 1 and .5 diamond pastes that I'd like to convert into a travel strop. I tried cleaning off the .5 paste with saddle soap and a toothbrush, but I'm not sure if it's clean enough for regular stropping.

If not I'll probably put some chromium oxide on it...

Thanks,
Josh
