The removal of lipstick stains on tableware by dishwasher capsules requires a combination of oxidation decomposition, alkaline saponification and emulsification by surfactants. The following are the specific methods:

First, the composition characteristics and cleaning difficulties of lipstick stains
The main components of lipstick include oils (such as wax and oil), pigments (such as organic dyes), and a small amount of wax. Grease is prone to adhere to the surface of tableware to form an oil film, while pigments may penetrate into the micro-pores or glaze gaps of tableware, making it difficult to completely remove them with regular water flow flushing.
Second, the cleaning mechanism and targeted ingredients of dishwasher capsules
Saponification of alkaline components
The alkaline components in the capsules (such as sodium carbonate) can undergo saponification reactions with the oil in lipstick, generating soluble soap and glycerin, reducing the viscosity of the oil and facilitating subsequent flushing.
The decomposition effect of oxidants
The oxidants such as sodium percarbonate contained in the capsules release oxygen when they come into contact with water, oxidizing and decomposing the organic pigments in lipstick, converting them into colorless or water-soluble substances, thereby achieving the effect of stain removal.
The emulsification and penetration effects of surfactants
Surfactants can reduce the surface tension of water, penetrate into the gaps between lipstick stains and tableware, wrap the grease into tiny particles suspended in water, and prevent re-adsorption.
Third, the tips for removing lipstick stains with dishwasher capsules

Choose the appropriate washing program
For tableware with a lot of lipstick stains, choose a high-temperature (above 70℃) and long-duration (more than 2 hours) washing program. High temperature can accelerate the reaction rate of oxidants and alkaline components, while long-term washing ensures that the components function fully.
Pre-treatment suggestions
Wiping to remove stains: For tableware with heavy lipstick stains, you can gently wipe with a paper towel or damp cloth before washing the dishes to remove most of the lipstick residue on the surface and reduce the burden of cleaning the capsules.
Soaking and softening: Soak the tableware in warm water for 5 to 10 minutes to soften the remaining lipstick stains, making subsequent cleaning easier.
Optimize the placement of tableware
Avoid overlapping: Ensure there are sufficient gaps between tableware to prevent lipstick stains from being blocked or water from flowing through.
Place the side with lipstick stains facing down to facilitate direct flushing by water.
Fourth, effect evaluation and improvement
Effect evaluation method
Visual inspection: After cleaning, observe whether the lipstick stains on the surface of the tableware have been completely removed and whether there are any remaining color spots.
Hand feel test: Touch the surface of the tableware with your hand to check if there is any sticky feeling or residue.
Improvement direction
Ingredient adjustment: Adjust the proportion of oxidants, alkaline components and surfactants in the capsules based on the actual cleaning effect.
User feedback collection: Collect users’ feedback on the cleaning effect of red stains on the mouth and optimize the product in a targeted manner.
Fifth, Common Problems and Solutions
Reasons for lipstick stain residue
Insufficient capsule dosage: Increase the capsule dosage appropriately based on the number of tableware and the degree of stains.
Low water temperature: Check the water temperature setting of the dishwasher to ensure it is within the recommended suitable temperature range for the capsules.
Insufficient washing time: Extend the washing time or choose a stronger washing program.
Solution
Secondary cleaning: For particularly stubborn lipstick stains, the secondary cleaning function can be enabled or manual pre-treatment can be done.
Regular maintenance: Regularly clean the dishwasher’s spray arm and filter to prevent insufficient water flow due to blockage.
