only if wet or under direct sunlight
no..........
fade them
Yes. Without pre-treating the canvas material, even the "permanent" sharpie will run, fade, etc. Make sure to pre-treat all material before decorating and washing.
Laundry detergent doesn't remove Sharpie because Sharpie is water-resistant and most detergents are made and are used in water, so it would only make the ink fade. To get Sharpie out of clothes or something I would suggest rubbing alcohol.
Chlorine is an oxidizing agent. It oxidizes the dye or pigment of the cloth and fades the colour.
Spray-on tan, yes. A real tan, no.
Buy a clear cover so no one can mess with it and it won't fade.
They do not recommend the Sharpie for letter writing as it is solvent base ink and will saturate through paper. They also do not recommend the Sharpie for use on cloth as it might bleed, fade or run in the wash. Also, over time a yellow halo may appear around the marking.
Depends what color most dark colors shouldn't have any affect some of the lighter colors fade slightly.
no! it also doesn't fade them like chlorine (or your skin, hair ...)
Yes, Sharpie ink doesn't come out of clothing. As a teacher ink and pen marks is one of the hazards of teaching because I get ink on my clothing at various times and have never found a soap/spot remover that will take out the ink.
