Concentrated cleaning tablets are small dissolvable tablets that turn tap water into all-purpose, glass or bathroom cleaner. You keep one sturdy spray bottle and refill it, instead of buying a new plastic bottle that is mostly water each time. They take up a fraction of the space in your cupboard.
Quick answer: Fill a reusable spray bottle with warm tap water to the line, drop in one cleaning tablet, wait for it to fully dissolve (often a few minutes), then cap, label and shake. Refill the same bottle with a new tablet when it runs out.
Why switch to cleaning tablets
Most spray cleaners are mostly water, packed in a new plastic bottle with a trigger sprayer you throw away when it is empty. Tablets ship as small, light packets, often in paper or cardboard, and you add the water at home.
Packaging is a big part of what households throw away. The U.S. EPA reports that containers and packaging made up 82.2 million tons, or 28.1% of all municipal solid waste, in 2018. Only about 13.6% of plastic containers and packaging were recycled that year, and over 69% went to landfills (EPA). Reusing one bottle for years keeps many of those plastic bottles out of the trash.
What you need
- A sturdy, refillable spray bottle (glass or thick plastic), one per cleaner type
- Cleaning tablets for the jobs you do most: all-purpose, glass, bathroom or kitchen
- Warm tap water
- A label or marker so everyone knows what is in each bottle
How to switch to concentrated cleaning tablets
- List what you use. Look in your cleaning cabinet and note the sprays you actually use. Most homes need only two or three: all-purpose, glass and bathroom.
- Pick a brand and starter kit. Many tablet brands sell starter kits with a reusable bottle and a few tablets. Look for the EPA Safer Choice label, which marks products with ingredients that are safer for people and the environment (EPA Safer Choice).
- Reuse bottles you already have. You can rinse out an empty spray bottle from an old cleaner. Wash it well first so leftover chemicals do not mix with the new solution.
- Fill with water first. Add warm tap water to the fill line given on the tablet package. Adding water first helps prevent foaming.
- Drop in the tablet and wait. Leave the cap off and let the tablet dissolve fully, often a few minutes. Then screw on the sprayer and shake gently.
- Label each bottle. Write the cleaner type and the date you mixed it. Follow the package for how long mixed solution stays good.
- Start in one room. Try it on a kitchen counter or bathroom mirror first. Once you like the results, replace your other sprays as they run out.
Tips
- Never mix different cleaners or tablets in one bottle. Some cleaning chemicals react badly together.
- Store tablets in a dry spot, sealed, and out of reach of kids and pets. Some look like candy.
- Use up the cleaners you already own before switching, so nothing goes to waste.
- Scent is personal. Many brands offer unscented or several scents, so try a few to find the one your household likes.
Frequently asked questions
Do cleaning tablets work as well as regular spray cleaners?
For everyday jobs like wiping counters, glass and sinks, many people find they work about the same. For heavy grease or soap scum you may need a specialty product or a little more scrubbing.
Are cleaning tablets cheaper?
Often, over time. The first kit with a bottle costs more, but refill tablets usually cost less than buying a new full bottle of spray cleaner. Prices vary by brand, so compare the cost per bottle.
Do cleaning tablets disinfect?
Most all-purpose tablets clean but are not registered disinfectants. If you need to disinfect, look for a product that says it is EPA-registered for disinfecting and follow the label’s contact time.
Can I use any spray bottle?
Yes, if it is clean, sturdy and holds about the amount of water the tablet calls for. Glass bottles last the longest, and a thick plastic bottle works fine too.
