All-purpose cleaner

Use dissolvable cleaning tablets (like Blueland) in a reusable spray bottle. Each tablet costs about $2 and replaces a full bottle of cleaner, eliminating single-use plastic bottles.

Mix equal parts white vinegar and water in a reusable spray bottle. Add a few drops of essential oil for scent. Works great on countertops, glass, and most surfaces. A gallon of vinegar costs about $3 and makes dozens of bottles of cleaner.
