I've done it. I bought Citra Solv from Ecohip in the UK It came fast and I've been playing iwth it all afternoon. It seems to be me to be very hit and miss. You really have to slop it on but even then sometimes it just doesn't do anything. The 80's National Georgaphic's didn't seem to do it at all but the 2000's mostly do but not always. I have taken a couple of pictures of what I have done today but really I left taking the pictures too late so they are a bit blurry cost the flash is too reflective. I have about 50 pages and will go through them all properly over the weekend. This first one didn't dissolve properly so while it was still damp, I used a brush..
