DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cleaning an object to be cleaned, a cleaning composition used for cleaning, and a bag.

[0002]

2. Description of the Related Art Conventionally, cleaning of a filter or the like to which fine dirt is liable to adhere has been mainly performed by suction with a vacuum cleaner or scrubbing with a sponge or a brush using a household detergent. However, it was difficult to remove viscous dirt such as tar, fine dirt, and shadows only by suction. In addition, these cleaning methods are complicated in that there is a risk that the cleaning object may be damaged by rubbing, and dirt may be scattered. Furthermore, it was not satisfactory for the user, for example, a sufficient cleaning effect could not be obtained, the water area was too narrow, and the frequency of cleaning increased. In recent years, along with changes in the living environment and the like, household appliances using filters other than air conditioners such as air purifiers have become very popular, and opportunities for cleaning filters have been increasing accordingly.
On the other hand, filters, etc., can fit in the kitchen sink individually, but depending on the washing method, they need to be as large as the number of filters at the time of washing.These washing methods are mainly time-consuming and cumbersome rubbing. However, it was not easy if there was not enough water in the home, such as a bathroom or a kitchen.

[0003]

Washing Test Method of Examples 1 to 4 and Comparative Example 1 The test filter is put into a bag of a plastic sheet for washing, and the detergent composition is poured. The amount of the detergent composition used was 100 mL for one filter / bag washing, and 300 mL for 6 filters / bag washing. The inside of the filter is sealed with a chuck attached to the opening of the bag, laid down, and the entire surface of the enclosed filter is immersed in the cleaning composition inside the bag. In order to completely immerse the entire surface of the filter in the cleaning solution, lightly press the upper portion of the bag body several times and then leave it for several minutes, take out the washed filter from the bag body, and thoroughly rinse with running water from the back surface of the filter, Thoroughly dried.

Comparative Example 2 (commercially available foam filter cleaner)
Washing test method After removing dust from the back of a filter soiled in a water place such as a bathroom by running water washing, the filter is placed horizontally on the floor with the back of the filter facing down. At this time, make sure that there is no overlap between filters. After spraying the foamed filter detergent on the entire surface of the filter and leaving it for about 20 minutes, washing with running water is performed while gently rubbing with hand. The washed filter was dried.

In the cleaning test method of Test Example 1, (a)
Detergency, (b) rinsing properties, and (c) simplicity of the cleaning method were evaluated based on the following evaluation methods.
