Seventh Generation Natural Glass & Surface Cleaner cleans without streaks, and is 1% solvent and VOC free. Most conventional glass cleaners are made with solvents: alcohols that are toxic (typically poisonous), ammonia, which is a respiratory irritant, or glycol ethers that cause systemic organ damage. Unlike these cleaning products, our product does not create unpleasant fumes and will not leave harmful residues. We guarantee you'll be able to smell the difference. Our Natural Glass and Surface cleaner is Non-toxic, Hypo-allergenic, Biodegradable, Vegetable based and contains NO dyes or fragrances.
