The 7 Best Eco-Friendly Products Your Home Cleaning Kit Is Missing

9 Elements Bathroom Cleaner ($25)

This bathroom cleaner makes quick work of soap scum, hard water buildup, and grime, according to Amazon reviewers who've used it on ceramic, tile, porcelain, and more. If you're unfamiliar with the brand, it's known for keeping things simple. Every product features nine ingredients or fewer (hence the name). This particular formula is powered by vinegar for deep cleaning but balanced with eucalyptus essential oil, so the scent isn't too overpowering.
