Enviro-orange Multi Purpose Cleaner. Use Enviro Orange for all of your cleaning needs, from home use to industrial applications. It can be used in many ways. In solution, it can be applied with a spray bottle. Enviro Orange’s lifting agent, a blend of d-Limonene and sodium metasilicate, gets into the pores of a material to lift and remove anything which is not permanently bonded. Some stains contain permanent dyes which may or may not be removable (such as some juice stains or permanent marker).
