Artist Reply: I get very aggressive with lifting. I prefer using a flat synthetic bristle oil or acrylic brush that has been thoroughly wet. I scrub then blot and I try to do it before the pigment has a chance to set. It pays to know your paper as sizing may vary between brands in quality, amount and paper weight so do some experimenting to know how your paper responds to your method of removal. I like Lana Aquarelle for large works because it is whiter than Movlin Papier d'Arche and the image reads better, but Movlin paper is sized better and is more amenable to aggressive scrubbing. Movlin Papier d' Arche is double elephant (29.5"x 41.25") is double sized and has a very distinct gel-size coating and lifting pigment is really easy. For really tough scrubbing over small areas I like to wet the pointed end of an Incredible Nib tool and scrub away. Scrubbing is always followed by blotting. I used to be able to get Winsor & Newton gel size and would apply it to heavily scrubbed paper that had surface damage. I first burnish the scrubbed area with a hard polished utensil then apply the sizing medium. The handle end of a stainless steel butter knife works well for me. I have heard you can use something like Knox Gelatin as sizing, but I don't know about that, I have never used it and would be careful.
