I hate cleaning my stencils. They usually tear or bend, so unless it's really clogged or heavy with paint, I just gently wipe off while wet, and that's it. Some stencils, like these pictured from the day care center job, I use repeatedly, so I do need to make the effort to clean. Over the years I've tried several methods, but I can't say any of the methods really worked great. Then, a few weeks ago when I was doing that Beacon Hill ceiling job, Stacy had a product called Krud Kutter with her that we used to clean our trowels. It worked so well, I immediately thought I should try it on my stencils. I found this product at my local Home Depot. What I like about it is a) it actually works and b)it has no strong odor to take my breath away, such as Simple Green.
