The calculators and quizzes on Cleaner Calcs give general household-cleaning guidance and planning math. They are not safety, medical or professional cleaning advice.

Estimates for planning

Every result on this site is an estimate based on the numbers you enter and on simplified formulas and default values. Real outcomes depend on your own situation, and defaults are examples, not quotes or promises. Please confirm anything important with the right professional, product label or official source before you act on it. Use of this site is at your own risk.

Never mix cleaning products

Do not mix bleach with ammonia, vinegar, rubbing alcohol, hydrogen peroxide or other cleaners unless a label tells you to. If you smell fumes, leave the area and get fresh air. If anyone has been exposed or feels unwell, call Poison Help at 1-800-222-1222 in the United States, or 911 in an emergency.

Always follow the label

The product label is the authority for its own product, including how to dilute it, how long it must stay wet to disinfect and which surfaces it is safe on. If a page and a label disagree, follow the label.

Surfaces and spot tests

Cleaners can etch, discolor or damage stone, grout, wood, metal and finishes. Test in a hidden spot first, and ask the manufacturer of the surface if you are unsure.

Skin, eyes and sensitivities

Cleaning products can irritate skin, eyes and airways, and some people are more sensitive than others. Wear gloves and eye protection when the label says to, avoid breathing fumes and rinse with water if a product gets on your skin or in your eyes. Follow the first-aid directions on the label and call Poison Help if you are worried.

Children, pets and ventilation

Keep cleaners out of reach of children and pets, rinse surfaces that food or skin will touch and ventilate the room. Some common ingredients, including certain essential oils, can be toxic to animals, so ask your veterinarian before using them around pets.

Homemade recipes

Do-it-yourself recipes, including laundry detergent and laundry stripping, are widely shared but are not tested standards. Check your washer manufacturer’s guidance, especially for high-efficiency machines.
