[0010] The pH of the cleaning solution of the present invention is required to be weakly alkaline of 8-11. When the pH is less than 8, the fatty acid of the soap in the washing solution is released, and a sufficient detergency cannot be obtained. On the other hand, when the pH is more than 11, there is a problem in terms of safety, which is not preferable. Such a pH may be appropriately adjusted according to the pH of the cleaning solution. As a means for adjusting the pH,

[0012]

Next, the present invention will be described with reference to examples, but the present invention is not limited to these examples.

Example A cleaning solution having the composition shown in Table 1 was prepared and filled in an aerosol container together with LPG. The composition of the cleaning liquid and LPG was 90% by volume of the cleaning liquid and 10% by volume of the propellant. (1) Detergency and (2) Foam performance were evaluated using these actual products and comparative products. The evaluation method is as follows. (1) Detergency The applied product and the comparative product were sprayed on the net surface of a screen door left outdoors for a long period of time, left for 5 minutes, washed with water, the state of cleaning of the net surface was observed, and evaluated according to the following criteria. ：: Dirt completely removed △: Part of dirt remained ×: Dirt was hardly removed (2) Foam performance Immediately after spraying the actual product and the comparative product on the screen of the screen door And the amount of foam adhering to the window glass was observed and evaluated according to the following criteria. ：: few bubbles passed through the screen △: slightly bubbles passed through the screen ×: many bubbles passed through the screen

[Table 1]

[Table 1]

As a result of the test, all of the products of the present invention were characterized in that they did not scrub when cleaning the net surface, and that there were few bubbles passing through the net surface. On the other hand, as shown in the comparative product, when the glycerin fatty acid ester of the component (B) is not blended or is less than a predetermined amount (comparative products 1, 2, 4), the components (A) and (C) ) Is out of the predetermined range (Comparative products 3, 5, 6,
7, 8) or when the amount of the component (D) sequestering agent exceeds the predetermined range (Comparative product 11), the foaming performance was inferior. When the pH was neutral (Comparative product 9) or when the component (D) was less than the predetermined amount (Comparative product 10), the detergency was insufficient. Therefore, the usefulness of the cleaning composition of the present invention, in which specific components are blended at a specific ratio, is apparent in a screen door cleaning agent in which evaluation of foam performance is important.

[0016]

The detergent composition for screen doors of the present invention is easy to use because it is an aerosol type, has sufficient detergency, and has a small amount of bubbles passing through the screen when sprayed.
The net surface such as a screen door or an air conditioner filter can be efficiently cleaned.
