What special precautions should be taken when cleaning and maintaining this Baby Walking Bike made of polyurethane, nylon and polypropylene?

Because materials such as polyurethane, nylon and polypropylene are sensitive to certain chemicals, avoid using detergents containing bleach, strong acids or strong alkalis. These chemicals may corrode the surface of the material, causing fading, deformation or aging. It is recommended to choose a mild neutral detergent or a non-additive laundry detergent specially made for infants and young children for cleaning. These detergents are usually gentle and will not damage the materials, while effectively removing stains.
For hard parts such as the frame and handrails, you can use a damp towel or soft cloth to dip in an appropriate amount of detergent to wipe. Be careful to use moderate force to avoid scratching the surface of the material. For difficult-to-wipe gaps or stubborn stains, you can use a soft brush (such as a toothbrush) to gently scrub. Avoid using hard objects or sharp tools when scrubbing to avoid damaging the material. Try to avoid soaking the Baby Walking Bike as a whole in water to avoid swelling, deformation or aging of the material. You can use a local cleaning method to focus on the stains.
When cleaning, pay special attention to the joints, rivets and other connection parts of the frame. These parts are prone to dust and dirt accumulation and are difficult to clean. You can use cotton swabs or slender tools to clean them to avoid detergent penetration and rust or loosening. Fabric parts such as seat cushions and awnings should be removed and cleaned regularly. When cleaning, follow the instructions on the fabric cleaning label and use detergents and washing methods suitable for the fabric. Avoid using bleach or high-temperature drying to avoid fading or deformation of the fabric.
After cleaning, use a dry towel or absorbent paper to wipe off the moisture on the Baby Walking Bike. Especially in the joints and connection parts, make sure that there is no moisture left to avoid rust or corrosion. If conditions permit, the Baby Walking Bike can be placed in a well-ventilated place to dry naturally. Avoid direct exposure to sunlight to avoid aging or fading of the material.
In order to keep the Baby Walking Bike clean and hygienic, it is recommended to clean it regularly. Especially in the parts that are easily accessible to babies, such as armrests, seat cushions, etc., they should be cleaned more frequently. After each use of the Baby Walking Bike, check for stains or dirt residue. If found, clean it immediately to avoid stains that become difficult to remove after a long time.
