Once you start cleaning, you need to make sure that every corner of the house is clean. In particular, pay attention to the 6 locations below, because they are easy to accumulate dirt but are difficult to see, so they are often overlooked during the cleaning process.

1. Bathroom drain

If the drainage system is not cleaned for a long time, hair and dirt will accumulate, causing blockage and slowing down the flow of water. This not only leads to unpleasant odors but also creates conditions for bacteria to grow, silently affecting the health of the family.

To clean this area effectively, you should remove the drain cover, filter and drain core, then use a brush to clean thoroughly.

To save time and effort, you can buy a special drain cleaner to pour into the drain.

- If the pipe is clogged, the cleaner will use chemical action to break down dirt, helping to clear the drain quickly.

- If the drain is not clogged or only shows signs of slow water drainage, the cleaner will adhere to the pipe wall, helping to protect and effectively deodorize.

2. Shower

Showers are prone to limescale and dirt accumulation in the spray holes after a period of use. If this condition is mild, it can cause the shower to discharge water unevenly, and if severe, it can affect the quality of water in contact with the skin.

Therefore, when "general cleaning" the house at the end of the year, do not forget to clean the shower - an item you use every day.

To effectively remove dirt in the spray holes, you just need to prepare a basin, mix a little citric acid descaling agent into the water, then soak the shower in this solution for about an hour. After removing, just rub it lightly, the stain will be completely removed, returning the shower to its shiny new look.

3. Kitchen Countertop

The black border around the sink area may be due to mold growth. This not only reduces the aesthetics of the kitchen space but also directly affects hygiene, because this is where you cut, slice and wash food every day.

If you want stains and mold to disappear quickly, you can use a specialized mold removal gel. Apply the gel to the affected areas, then leave it for about 3-4 hours. After this time, you will see the mold disappear. Finally, just use a clean cloth to wipe off the remaining gel.

4. Electric toothbrush, face washing machine...

Electric toothbrush, face washing machine... are personal hygiene devices that are often placed in the bathroom for convenient use. However, the humid environment in the bathroom can cause these items to gradually form black stains or mold. This not only reduces aesthetics but also affects health, because they come into direct contact with the skin, hands and mouth.

Like the way you deal with black stains on the table top, you can use multi-purpose mold removal gel to clean the dirt on electric toothbrushes and face washing machines, making them clean and safe to use.

5. Pillow core

After a period of use, most pillows can encounter the problem of dirt accumulating in the pillow core. If not cleaned promptly, this can silently affect health.

Cleaning the pillow core is not difficult. For pillows with cotton cores and 3D fibers, you can completely wash them in the washing machine. As for pillows made of feathers or rubber, you should hand wash them to ensure quality and durability. In particular, for foam pillows, bead pillows or pillows made from natural materials, you should not hand wash or machine wash them, but dry them in the sun to clean and deodorize effectively.

6. Inner wall of microwave ovens and ovens

When using microwave ovens, ovens and other kitchen appliances, many people often focus on cleaning the outer surface and accidentally forget the inner wall of these devices. Although it is difficult to see, this is the area that comes into direct contact with food, is prone to grease and dirt, and over time will accumulate bacteria.

For effective cleaning, you can use baking soda mixed with water to create a paste (suggested ratio: 1 part baking soda and 2 parts water). Then, turn on the microwave or oven and heat it for about 5 minutes, so that the high temperature helps the baking soda break down the grease and clean the stains.

After heating and waiting for the oven to cool, use a clean cloth to wipe away the stains. With this method, stubborn stains stuck to the inside of the device are quickly cleaned, returning the microwave and oven to a shiny new look.
