ECOS All-Purpose Cleaner is a great general cleaner that works well on non-porous or sealed surfaces where streaking is not normally an issue. Use it on wood surfaces like furniture and floors, walls, porcelain and ceramic, linoleum, laminate, concrete and stone surfaces like marble and granite.
ECOS Window Cleaner works best for surfaces that are clear or reflective because it dries quickly and prevents streaking. It works great on glass, mirrors, windows, clear plastics like plexiglass and metal surface like stainless steel (but for a deeper clean and polish, try ECOS Stainless Steel Cleaner + Polish).
