When your bottle of toner is running low and you have a refill pouch ready, you may wonder whether to wash the container or simply top it up as it is. Rinsing it with water just because you want it to be clean may conflict with the instructions for the product you own. Before opening anything, set the bottle and the pouch side by side and check the compatible container and how to transfer the liquid.
Here we explain, in five steps, what to check before and after pouring the liquid from the pouch into the compatible bottle. Whether washing is needed, the conditions for using it up, the amount to transfer, and when to replace the container differ from product to product. Do not apply steps you learned with another toner; the starting point is to read the labels of the combination you are using today from start to finish.
1. Match the product name, type, and compatible container of the bottle and the pouch

First, read the product name on the bottle and the product name on the front of the pouch side by side. Even within the same series, the type, such as moist or refreshing, or the time of sale may differ. Do not judge that the contents are the same and that it fits the same container just because the container color or the look of the packaging is similar.
Next, check the "how to refill" instructions on the back of the pouch and the specified bottle. Not only the condition that it is the same brand, but also which product name and type of bottle it says to transfer into, should be compared. If you cannot confirm the match, do not open the pouch; finish checking the combination first.
Even a liquid labeled as a refill cannot be put into just any commercially available empty bottle. The conditions of use may be set down to the pump structure, the inside of the container, and how it closes. Think of changing from the designated bottle to a different one because a smaller container is easier to hold as a separate matter.

If the label on the bottle has peeled off and cannot be read, do not guess the contents from the color alone. Also check that it has not been mixed up with a family member's item or a container that previously held a different toner. By leaving out of the candidates for reuse any container whose contents you cannot identify, you avoid a mixture that cannot be verified later.
The capacity is also one thing to look at. Even if the numbers on the bottle and the pouch differ, do not immediately decide that something is insufficient or wrong; read the amount specified for that combination. Do not aim to fill it to the brim; check which container it is meant to be transferred into and how far. Also check whether the shape of the opening and the closing marks match the diagram of the bottle.
2. Read the instructions on the remaining amount and on washing and drying before transferring

Once you know the compatible container, check how much liquid is left in it now. If there are instructions such as "after using it up" or "all at once," open the pouch only after meeting those conditions. Do not change to a way of using it where you add new liquid each time it goes down a little; decide how to handle the old and new liquid according to the labels of the products you own.
Whether to wash the container is also something to check for each product. Some products say to use the empty bottle without washing it, while others say to wash the bottle and pump and dry them thoroughly. Neither is a procedure common to all toners. Read the instructions for the product you are refilling, and then choose the preparation that is needed.
When washing is specified, check whether it applies only to the bottle or includes the pump, and also the washing method and the drying. Even if the outside is dry, water may remain inside or in the pump tube. Do not cut corners by thinking "I'm in a hurry, so a light shake is enough"; while you cannot meet the specified drying conditions, wait without transferring the liquid.
If the instruction is to use it without washing, do not add steps such as running water through it or disinfecting it with alcohol or boiling water just to be safe. Conversely, also avoid pouring straight into a container that has already been washed without reading the instructions. If you cannot tell whether it can be returned to the state described on the label, go back to the checks before transferring, for example by preparing a new bottle.
Do not dilute the remaining liquid with water before transferring it, add a different toner, or return old liquid to the new pouch because you want to use up every last drop. The conditions for using it up and the preparation of the container are points to observe apart from any ideas for saving on quantity. Keep the pouch closed until the checks are finished, and do not start putting contents into a container that is still being prepared.
3. Prepare a flat work area and check how to open the spout

When you are ready to transfer, secure a bright, flat place where the bottle is stable. On the edge of a wet sink or in a spot where things are piled up, it is hard to work while holding the bottle with one hand. Clear away the things around you first, and keep separate places for the receiving container, the pouch, and the cap you have removed.
Clean your hands, and check that no water is left on your hands or the work surface. If you look for a cloth or a place to put the cap only after opening the pouch, you tend to end up holding the spout with your hand or setting it face down on the desk. Finish setting up your workspace first, and arrange things so you can work without carelessly touching the inside of the opening or the pump tube.
Check how to open the pouch by looking at its form, such as a tear line, a cap, or an insertion type. Some types do not need scissors, so read the label before cutting it wide open with whatever tool is at hand. Changing the opening position can make it harder to pour, so keep the shape of the opening specified for the product you own.

Do not leave the bottle open for a long time with its cap removed; read the instructions before proceeding to opening. If you avoid opening other refill pouches at the same time, you are less likely to mix up the contents partway through. If you also do a family member's item in a row, finish closing one combination before moving on to the next, and take care not to line up more and more open containers.
If the cut does not open well or the cap will not move, do not add methods such as pulling with your teeth or piercing it with a needle. Set it down in a stable place for now and review the position and direction for opening. Do not apply force while the container is tilted; treat resolving the opening problem as a separate stage before pouring.
4. Pour slowly into the specified position, and check the amount and how it closes

Steady the bottle, and align the mouth of the pouch with the position shown on the label. Check the diagram for the product you own, such as whether it says to insert the spout into the bottle and which one to tilt. Pushing it in deeper is not necessarily better. Do not squeeze the pouch hard and force the liquid in by momentum while the openings are not aligned.
Once you start pouring, proceed slowly while watching the flow of the liquid and the opening of the bottle. If it spills or the liquid overflows at the opening, stop once instead of pushing further. Check whether the bottle is tilted, whether the opening has shifted, and whether you have exceeded the specified amount, and do not pour in more while the cause is unknown.
If the instruction is to transfer the whole amount at once, do it with the compatible empty container and the preparation in place. However, this is different from forcing in leftover liquid. If the expected amount does not fit, check the original remaining amount, the compatible container, and whether you misread the capacity, and do not gather up spilled liquid and return it to the bottle or the pouch.
When you have finished pouring, arrange the opening and the handling of the cap according to the label, and close the inner plug, pump, and cap in the specified order. If there are alignment marks, check up to those marks. Do not assume that any container will close if you twist it hard; check that it is not going in at an angle, and do not force the shape to fit with closing force.
To check that it has closed, there is no need to turn it upside down and shake it hard. Check the marks and how the cap sits by the method shown for the product you own. If the movement of the pump changes, do not go as far as modifying it, such as cutting the tube or widening a hole; reread the original way of attaching it and the operation for starting use.
5. Keep the manufacturing code and replacement timing on record to prevent mix-ups next time

Before putting things away, keep a record of information that the pouch says to retain even after refilling, such as the manufacturing code. If you record the date of transfer together with the product name and type, you can check it again the next time you prepare the same contents. The record is not for deciding a new expiration date on your own judgment, but for knowing what you transferred and when.
If there is guidance on when to replace the container or how many times it can be refilled, check it against that product's conditions. Do not use the number of times for another toner as a uniform standard. Also look for changes you should check before using it repeatedly, such as a cap that will not close, a cracked container, or a change in the condition of the pump.
If the color, smell, or condition of the contents is different from usual and bothers you, do not judge the cause or safety from appearance alone. Do not dilute it by adding new liquid or keep using it after moving it to another container; stop using it and check how to get advice for the product you own. Even when the original color or properties are described, it is important not to fill in gaps with information about another product.
For storage, follow the temperature and sunlight conditions on the container label. Do not transfer it into a drink container or return it to the sink without knowing the product name; put it away with the label on the bottle left in place. Dispose of the empty pouch according to your local sorting rules, after confirming that you have kept the information you were to retain.
At the next refill, check in this order: matching the bottle and the contents, the remaining amount and washing conditions, the work area and opening, how to pour and close, and the record and storage. If you are concerned about spills when applying it to your face, you can also refer to how to pick up and carry toner in your hand. Keep the work of transferring into the container separate from the work of applying it to your skin, and proceed with both according to the amount and steps for the product you own.
