Here's the Citrasolv website, where you'll find lots of info and examples.
I couldn't wait to try it! The only problem was I didn't have any Citrasolv! It is, of course, an American product. Anyway, back in about 1995 while visiting the USA, I bought some stuff called Goo Gone. Like Citrasolv it is a citrus based cleaner, albeit made with petroleum distillates, which Citrasolv doesn't have. My American host was using some to get rid of the sticky mess left by labels when you try to get them off, and because at that time I had never found anything here which would do that easily, I bought some to bring home.
I didn't know whether Goo Gone would work in the same way as Citrasolv, but decided it was worth a try. I had about a third of the bottle left (been using it very sparingly!) First I tried it with an old magazine, but nothing happened. The inks didn't shift at all. Apparently many of the artists on the website use National Geographic mags, something to do with the type of ink and the fact that the photo pages are clay coated. So I scrounged a couple of old copies from my daughter.
They worked a treat! The Goo Gone produced some great papers, which I then scanned on the computer. Just wish I'd thought to scan the original photos too before I altered them, to compare. I'll remember next time! Since you'll never get the same result twice, it makes sense to scan your original altered pic, which you can then keep, and use a printed copy in your project. Once you've got your printed copy, you can then enhance it however you wish.
These are a few of the best results.
And here's a card I made with the first one. I used my graphics programme to add the butterfly (one of my own photos) , and stamped the sentiment (by The Craft's Meow).
To the second paper I added a stamped fairy, some leaves hanging down from the top (both Lavinia Stamps) and some tiny butterflies (The Craft's Meow). I used a fine drawing pen to turn some of the blobs into flowers, and enhanced some of the elements, including the fairy's wings, with glitter glue.
Knowing I would want to do more, (and by then having only a few drops of my precious Goo Gone left!) I went online to see if I could get hold of some Citrasolv. Found it on Am*z*n, and ordered some forthwith.
There's a very good YouTube video by Cathy Taylor, one of the artists profiled on the Citrasolv website. Once you find that one, which is a good one for the basic instructions, it will then lead you to others.
I haven't yet had time to try it with the Citrasolv, but I have high hopes for it! And if it doesn''t work, at least I have a replacement for the Goo Gone!
