Blood and urine stains on furniture not only affect the appearance, but may also breed bacteria, cause odors, and even endanger health. This article combines microbiology, cleaning science and home care practices to sort out a set of efficient solutions.
Ⅰ. How to get blood out of furniture?
1. Take action immediately
Once blood stains solidify, cleaning becomes twice as difficult. After discovery, rinse with cold water immediately (hot water will accelerate protein coagulation, making blood stains more difficult to remove), and press with a clean towel to absorb excess liquid. If it is fabric furniture, you can remove the kit and handle it separately.
2. Natural stain removal method
① Salt and cold water mixture: suitable for fresh blood stains. Dissolve salt in cold water into a paste, apply to the stain, let it stand for 10 minutes and then scrub.
② Hydrogen peroxide (use with caution): suitable for white or light-colored fabrics. Hydrogen peroxide can decompose the protein in the blood, but it is necessary to test whether it fades in an inconspicuous place first, and it needs to be rinsed thoroughly after use.
3. Professional stain remover selection
Recommend products with active oxygen formula (such as Dr. Beckmann interior decoration stain remover), which decompose blood stains through oxidation reaction and are safe for most fibers. Follow the instructions when using and avoid soaking to prevent dye loss.
Ⅱ. how to get urine smell out of furniture?
1. Emergency treatment
After urine penetrates into the furniture, it must be quickly blotted up to avoid deep penetration. You can press it with an absorbent towel and sprinkle baking soda on it and let it stand for 2 hours to absorb the residual liquid.
2. Neutralize odor and disinfect
① Enzyme cleaner: Contains protease ingredients that can decompose urea and uric acid in urine. After spraying, let it stand for 30 minutes before wiping. It is especially suitable for fabrics and carpets.
② White vinegar solution: dilute white vinegar in a 1:1 ratio and let it stand for 15 minutes after spraying. Acetic acid can neutralize ammonia odor, but be aware that some materials (such as leather) may be damaged.
3. Dealing with stubborn odors
If the odor persists, you can use deodorizing products containing Freshplex™ technology (such as Kobayashi Pharmaceutical Deodorizing Granules), which remove odors through adsorption and chemical reaction, and are suitable for areas that are difficult to clean thoroughly, such as sofa gaps and mattresses.
Ⅲ. Preventive measures: Reduce pollution risks from the source
1. Regular deep cleaning
It is recommended to use a steam cleaner to sterilize fabric furniture at high temperature every quarter; leather furniture requires special care agents to maintain the antibacterial coating.
2. Anti-fouling barrier
Spray nano-scale anti-fouling spray (such as fluorocarbon products) to form an invisible protective film to prevent liquid penetration. Experiments show that such products can reduce stain attachment by 80%.
3. Environmental control
Keep indoor humidity below 60% to avoid microbial growth. Dehumidifiers (such as Purify models) can be used in dark bathrooms or humid areas, and their nanoe technology can purify the air simultaneously.
IV. Precautions for special materials
1. Leather furniture: Alcohol or acidic detergents are prohibited. It is recommended to use pH-neutral leather cleaning cream and apply maintenance oil after cleaning to prevent cracking.
2. Solid wood furniture: Urine may corrode the paint surface. It needs to be wiped lightly with a damp cloth first, and then repaired with wood wax oil. If it has changed color, it needs professional polishing and renovation.
3. Memory foam mattress: Urine can easily penetrate the interior. The outer cover can be removed and washed in a cold water machine, and the inner core can be sprayed with medical-grade hydrogen peroxide solution (3% concentration) for sterilization.
V. Scientific perspective: Why are these methods effective?
1. Biodegradation principle: The protease in the enzyme cleaner can target the protein in the urine and eliminate the source of odor at the molecular level.
2. Redox reaction: The active oxygen component releases oxygen free radicals to destroy the organic pigment structure of the blood stain, achieving the dual effects of bleaching and disinfection.
3. Physical adsorption: The porous structure of baking soda can adsorb volatile sulfides (such as hydrogen sulfide) and reduce the spread of ammonia odor.
