What can I use to safely remove Kodak Opaque Red from a Neg

Hi there,

I'm revisiting some of my older 8x10 black & white negs and one of my favorites has had some smaill emulsion pinholes covered up with Kodak Opaque Red. So my question is, does anyone know what I can use to safely remove the Kodak Opaque Red from the black & white negative ???

Thanks

It's water soluble.
