Instructions
The procedures for removing household clay, tobacco smoke and yellowed varnish from oil paintings are the same; merely the cleaning products are different. Gainsborough's oil painting cleaners are based on time-proven museum formulas. Avoid using h2o based formulas: water can seep through minute cracks and penetrate the sheet size, causing the paint to flake off in fourth dimension.
Before offset be sure to accept a photograph of both the front and the back of the painting. If there is any writing on either the forepart or the back take a close up photo. Take a photo upon completion for later comparison.
Step one:
Lay the oil painting to be cleaned face up up on a piece of kraft paper. Article of clothing surgical gloves to protect your hands and be sure to have adequate ventilation. Take care not to press down on the canvas too much or you will stretch the sheet. We propose using a slice of linoleum cut out from a sink under the expanse of the painting you are working on to prevent excessive pressure on the canvass.
Apply a rolling motion, rather than a scrubbing motion, when applying the cleaner.
Step 2:
Apply Gainsborough Neutralizer to a piece of cotton wool wool or white cotton fabric and gently wipe over the face of the oil painting to clean off the surface dirt. Use a cotton swab to test a corner of the oil painting with Gainsborough Emulsion Cleaner and Varnish Remover to determine which product will all-time clean the painting. Emulsion Cleaner volition remove dirt and smoke, whereas Varnish Remover will remove yellowed varnish in nearly cases. For more difficult or special situations, Kotton Klenser™, Varnish Softener, Mastic Varnish Remover, or Linoxyn Remover may be required. Immediately after each test, utilise Gainsborough Neutralizer to a clean piece of cotton and gently wipe over the exam expanse to neutralize the cleaning action.
Step 3:
Subsequently establishing which product to use, you can brainstorm cleaning the oil painting. Dip a cotton swab into the Gainsborough cleaning production yous have selected. Apply a rolling movement rather than a scrubbing motion when applying the cleaner. Watch your swab advisedly to be certain that yous are removing only dirt or varnish and not the pigment. Do not dip the swab into the cleaning product again, once information technology has been used. We recommend cleaning a 2" square area at a time and so neutralizing the area with Gainsborough Neutralizer before proceeding to another area. We propose doing the heaven at once, so the trees, etc. because it is easier to spotter for any color that might be coming off, and different pigments reply differently to cleaning.
