Removing a stain from a sink starts with identifying the sink material and the type of stain. A cleaner suitable for one finish may damage another. Follow the sink manufacturer’s care instructions before selecting a product.
Choosing a Cleaner
Hydrogen peroxide is an oxidizing and bleaching chemical used in some formulated cleaning products. Use a product only when its label permits the intended surface and application. Do not substitute concentrated industrial peroxide for a ready-to-use household cleaner.
For an unfamiliar stain, coated surface, or persistent discoloration, consult the manufacturer or a qualified surface-care professional. Follow any label instructions for compatibility testing, application, rinsing, and drying.
Avoid Homemade Chemical Mixtures
Do not mix peroxide with baking soda, vinegar, bleach, drain cleaners, or other chemicals unless the product manufacturer expressly specifies the process. Do not heat peroxide or use hot water to increase its activity.
Blocked Drains
A blocked drain is a plumbing problem, not an indication to pour concentrated peroxide into the sink. Follow the fixture manufacturer’s guidance or contact a plumber. Never combine drain-cleaning products or add peroxide to a drain containing another chemical.
Bubbling Is Not a Test of Cleaning Performance
Hydrogen peroxide can release oxygen as it decomposes. Foaming does not establish that a surface has been disinfected, that a stain will be removed, or that a product is compatible with the sink.
Handling Precautions
Follow the product label and concentration-specific Safety Data Sheet (SDS). Prevent skin and eye contact, avoid breathing mist or vapor, and use the specified protective equipment. Keep products in their original labeled containers, away from children and pets.
