Try Purel or any other brand(I buy the ones from the Dollar Store) and use it to clean paint from my stencils. Works great and doesn't smell like Goo Gone

GooGone or try white vinegar. I use white vinegar for lots of things.

That's why they make water soluble basting spray, so it washes out and cleans off easily.

This is the way I do it and have for years. There is another product called Erase but I haven't seen it sold for a while. The Goo Gone seems to have taken over the market. This does not damage your plastic and does not smell too bad either. You can use WD-40 in a pinch but the odor is awful and it is not as safe as the Goo Gone.

By the way, they make a nice stencil adhesive that comes in a bottle with a dabber that works great instead of the more powerful spray adhesive. It is sold near the stencils in the store. I prefer that.

I love this board. I get answers to questions that I haven't even thought of yet. Thanks for the advice.

Eucalyptus Oil usually does the trick with removing anything sticky. Good luck!

You could try nail varnish remover, it works on glass windows to remove sticky residue, try it and tell me how it works on your plastic. Just a small amount on a piece of fabric.

I use painter's tape to adhere my stencils to my quilt to mark. It doesn't leave a sticky residue and will come off easily, but does keep the stencil in one place while marking.
