First of all, you should regularly vacuum the fabric sofa. It is best if you can do it once a week. The armrests, backrests and gaps of the sofa must also be taken into account. Of course, it can also be wiped with a towel, but when using a vacuum cleaner, do not use a suction brush.
Secondly, clean the sofa once a year with a cleaning agent, but the cleaning agent must be thoroughly washed off afterwards, otherwise it will be more susceptible to dirt. As for the choice of detergent, a special detergent containing antifouling agent can be selected. Some silicic acid sprays have a dust-proof effect and can be sprayed once a month.
The jacket of the fabric sofa can generally be cleaned. The elastic sleeve may be washed in a washing machine at home, and the cotton cloth or linen jacket may be requested by the laundry. When ironing the sheath, it should be noted that some elastic sheaths are easy to dry and hot. Even if you want to iron, you should consider the appearance of the fabric. If the jacket is cotton, it is not suitable for ironing.
A pipette, also known as a pipette gun, is a device used to quantitatively transfer liquids. When conducting research in analytical testing, a small or trace amount of liquid is generally removed with a pipette. Pipettes can be divided into gas piston pipettes (Air-displacement pipette) and external piston pipettes (Positive-displacement pipette) according to the principle. Gas piston pipettes are mainly used for standard pipetting, and external piston pipettes are mainly used to handle special liquids such as volatile, corrosive and viscous. Many people ignore the correct use of pipettes and some of the details.
