Working with acetone

• Work outside or in a well-ventilated expanse.

How ofttimes should stencils be cleaned?

Stencils are created with a vast array of sizes, designs, and levels of item. They're besides used with all kinds of unlike paints and on dissimilar surfaces in unlike environments. Therefore, the frequency in which a stencil should be cleaned also varies greatly.

Paint tends to build in the little crevices and corners of a stencil blueprint. When this happens, the stenciled result may announced less precise. If it seems that a stencil isn't providing the best outcome for a project, it may be time to brainstorm the paint removal process.

How to remove dried pigment from mylar stencils

1. Remove dirt and droppings from stencil surface

Use h2o, a scrap of dish soap, and a rag to remove any dust or dirt from the stencil. Utilize Goo Gone to remove any sticky adhesives that may exist remaining. Goo Gone won't impairment the stencil.

ii. Use acetone to remove paint

For stencils small enough to fit into a shallow tray, cascade a very thin layer of acetone into the tray, plenty to submerge a single stencil. Wearing butyl rubber gloves, identify the stencil, paint side downward, into the acetone bath. Let the stencil soak for 15 minutes if spray paint was used, and 30 minutes if acrylic paint or latex pigment was used on the stencil. Some of the acetone will evaporate during this time. After a while, add a bit more if it looks similar the pigment on the stencil is no longer covered.

When removed from the acetone bathroom, the paint should be significantly loosened from the stencil'due south surface. Use a scrub castor or a rag to clear away the remaining pigment.

For larger stencils, place on a towel or drop material, pigment side upward. (Whatever the stencil is placed on volition probable end upwardly with paint on information technology.) Wearing butyl rubber gloves, and using your other hand to secure the stencil so information technology doesn't move, dab a small-scale amount of acetone onto the rag or scrub castor. In the larger, less detailed areas of the stencil, scrub back and forth or in circles until the pigment is cleaned away.

Note: The plastic may become stained if spray pigment is left on information technology for more than a few months. This does not impact the stencil's operation.

iii. Touch up detailed edges and corners

Using a Q-tip dabbed with acetone, lightly rub away excess paint. Get softly and slowly in detailed areas to avoid bending, breaking, or damaging the stencil. Paint may have stained the stencil's edges, only will not time to come stencil employ.

How to store and organize stencils

• Continue stencils equally flat as possible.
• Store stencils out of straight sunlight, ideally indoors at room temperature.
• Larger stencils tin be stored vertically, placed back into their original aircraft parcel or sandwiched between flat pieces of cardboard.

How nosotros tested and researched

We compiled other stencil cleaning methods and spent days testing to make up one's mind which worked best. Many articles suggest using mixtures of vinegar and water, or dish soap and a scrub castor. Trying every combination of ingredients and instructions we could find, we tested the methods on erstwhile, crusty stencils that take been laying around our warehouse in various forms - bent, flat, modest, large, left outdoors, covered in dissimilar types of pigment.

Vinegar, water, and dish soap are not annoying plenty (even with a scrub castor) to easily remove latex paint and spray paint. Afterwards trying other available methods, we recommend acetone every bit the best stencil cleaning solvent.
