Take a lyttle peece of a Spunge, or a Linnen cloath, being cleane without any soyle; wet it in water, and wring it hard, & wipe that you hauve written very lightly, and it wyll out, and within one quarter of an howre, you maye wryte in the same place agayne: put not your leaues together, whylst they be very wet with wyping. - Cleaning instructions from writing tables published by Robert Triplet in 1604
