Quick answer

Kinfill refills are concentrated formulas you mix with water at home. One refill makes 500 ML of cleaner. You add the concentrate to a reusable bottle, top up with water, and shake. This is different from ready-to-use cleaners, which are mostly water and come in single-use plastic. If you want less plastic and lower cost per bottle, a refillable cleaning system is the better choice.

What is a cleaning concentrate, and how is it different from ready-to-use?

A cleaning concentrate is a small amount of active cleaning ingredients that you dilute with water before use. Ready-to-use cleaners are already diluted, so you're paying to ship and store water. Concentrates cut packaging and transport weight, which is why refill systems use them. With Kinfill, one refill concentrate makes 500 ML of cleaner. You control the water, so you're not buying a new plastic bottle every time.

How do I mix a Kinfill refill?

Mixing cleaning concentrates is straightforward. Pour the entire refill into a clean 500 ML bottle, add water to the fill line, and shake gently. Use room-temperature water unless the label says otherwise. Don't add extra concentrate hoping for a stronger clean; the formula is balanced for the stated volume. If you have hard water, let the mixed cleaner sit for a minute after shaking so any minerals settle before you spray.

Do I need a special bottle or starter kit?

You don't need a proprietary bottle, but a refill starter kit usually includes a reusable bottle and sometimes a funnel. Any clean 500 ML spray bottle works if it seals well. The main advantage of a kit is convenience and consistent dilution. If you buy a year's supply of 12 refills from Kinfill, you'll receive a custom tin for storage, which keeps unused refills organized and away from light.

Are eco cleaning refills actually better for the environment?

Yes, mainly because they reduce plastic and shipping weight. A single reusable bottle replaces many single-use bottles. Kinfill refills are 100% biodegradable, so the formula breaks down after use. That said, the biggest impact comes from actually reusing the bottle and mixing correctly. If you mix a refill and then pour it down the drain, you lose the benefit. Store refills in a cool, dry place and use them within the recommended period.

Which Kinfill refill should I choose for my home?

Match the refill to the surface. The Kitchen Cleaner Refill is engineered to tackle grease around your stove and is safe for stainless steel and natural stone. The Multi Surface Cleaner Refill handles hard surfaces like wooden tables and marble countertops. The Yoga Mat Cleaner Refill uses tea tree oil as a natural disinfectant and neutralises odours on mats and sports equipment. All three come in different scents, so you can pick what you like. If you're unsure, start with the Multi Surface Cleaner for everyday messes and add the Kitchen Cleaner for cooking areas.

How much do Kinfill refills cost compared to ready-to-use?

Kinfill refills are priced at USD 7.44 for the Kitchen Cleaner, USD 7.56 for the Yoga Mat Cleaner, and USD 7.32 for the Multi Surface Cleaner. Each makes 500 ML. Compare that to a ready-to-use bottle that often costs more per millilitre and comes in single-use plastic. The comparison price shown is USD 12.00, so the refill is a clear saving. Over a year, the difference adds up, especially if you clean frequently.

Refill FAQs

How much water do I add to a Kinfill refill?

Add water to the 500 ML fill line on your bottle. The concentrate is pre-measured for that volume. Don't guess; a kitchen measuring cup works if your bottle lacks markings. Use the full refill for 500 ML of cleaner.

Can I use a Kinfill refill in any spray bottle?

Yes, as long as the bottle is clean and holds at least 500 ML. A dedicated bottle from a starter kit makes measuring easier, but it's not required. Any clean 500 ML bottle works.

How long does a mixed refill last?

Mix only what you'll use within a few weeks. Because the formula is biodegradable, it's best fresh. If you mix a full bottle and don't clean often, consider mixing half a refill at a time. Mix smaller batches if you clean less frequently.

Are Kinfill refills safe for all surfaces?

The Kitchen Cleaner is safe for stainless steel and natural stone. The Multi Surface Cleaner is for hard surfaces like wood and marble. Always test on an inconspicuous spot first, especially on porous stone. Match the refill to the surface and test first.

What if I have hard water?

Hard water can leave mineral residue. After mixing, let the bottle sit for a minute and use the clearer liquid on glass or shiny surfaces. For routine cleaning, it's usually fine. Let mixed cleaner settle if you have hard water.
