Getting blood out: sheets, mattresses, sofas and clothes

At a glance

Who it’s for: Anyone who has found blood on a sheet, a mattress, a sofa cushion or clothes.

Reading time: About 8 min

In three points:

  1. The label on the item, and the maker’s current instructions, come before any general tip. In Canada, care labels are voluntary; if one is there, it has to be accurate.
  2. Health Canada says: “Never mix household chemical products together. Some mixtures can produce harmful gases.”
  3. Readers’ habits appear here as habits, not tested advice. This Column picks no method.

Blood on a sheet or a cushion is part of ordinary life. Here is what care labels and makers say about cleaning it, what Health Canada says about using cleaning products safely, and what readers describe doing. Start with the label.

General information, not medical advice. For anything about your own health, talk to a healthcare provider. Where to get help

Editor’s Note

Dear reader,

I set out to write a simple stain guide. Then I looked for a textile-care authority to quote, and I could not reach one. One university had even retired its online stain guide. So this Column is honest about its sources. It starts with the care label and with Health Canada’s rules for household chemicals. It gives makers’ instructions, and readers’ habits as habits. It picks no method. Tell the Editor what works in your home.

— The Editor

In reader forums, many people describe waking to blood on the sheet, or finding it on a sofa cushion or a favourite pair of jeans. It is ordinary. It is nobody’s fault. This Column covers clothes, sheets, mattresses and sofas. It reports what care labels and makers say, and what Health Canada says about using cleaning products safely. It sets readers’ habits apart from those sources. It does not rank one method or product against another.

Start with the label

The care label is the first source. In Canada, care labels are voluntary. The Competition Bureau says: “Care labelling, in the form of either written words or symbols, is a voluntary program in Canada. If care information is included it cannot be false or misleading and must accurately reflect an appropriate method of care for the article (item).”

Glossary · Care label

The tag with washing and drying instructions. In Canada it is voluntary, but if it is there, it “cannot be false or misleading”. Says who? Competition Bureau Canada.

Glossary · Care symbols

The small pictures on a care label that stand for instructions such as washing, bleaching, drying, ironing and dry cleaning. Canada’s standard is CAN/CGSB-86.1-2003, “Care Labelling of Textiles”. Says who? Competition Bureau Canada.

So a care label, when there is one, has to be accurate. When there is none, you are working without instructions.

Stain advice also ages. A US university extension retired its online stain guide. It said: “Much has changed in the textile world since the Stain Solution website was created. We no longer have the expertise to confidently update the website to reflect those changes.” The Editor takes that as a lesson. The label on the item, and the maker’s current instructions, come before any general tip.

Health Canada’s safety rules

Before you use any cleaning product: Health Canada’s words

  • “Read the label and follow all instructions for safe usage when using household chemical products.”
  • “Never mix household chemical products together. Some mixtures can produce harmful gases.”
  • “You should never mix bleach products with other cleaning products because this can produce toxic gas.”
  • For bleach, Health Canada says: “Ensure proper ventilation by opening windows or doors and running exhaust fans, during and after using the product.”

If someone may have been harmed by a household chemical, Health Canada says: “Call a poison centre or your health care provider right away.”

Source: Health Canada, “Use household chemicals safely” (page modified 2024-02-20).

This box applies to every tip below, including readers’ tips. Health Canada says never mix household chemical products.

Clothes and sheets

What the sources say. The care label on the item comes first. If the label and a tip disagree, the label wins. Health Canada’s rules, above, apply to any product you use on the stain.

The Editor could not reach a textile-care authority’s method for blood stains. So this Column does not state one as fact.

What readers describe. These are readers’ habits, not tested advice. The Editor has not checked any of them:

  • for period underwear: rinsing until the water runs clear, skipping fabric softener and using an enzyme detergent;
  • keeping hydrogen peroxide in more than one room for stains;
  • keeping pyjamas just for period nights;
  • a lidded bucket for rinsed items until wash day.

Health Canada’s “never mix” rule stands, whatever the tip.

Period underwear and reusable period pads

These are made to be washed, so their makers give instructions.

A federal guide. A National Defence health guide says reusable period pads and period underwear “must be rinsed out by hand, using running water until the water runs clear”. It adds: “Most have a longer lifespan if they are washed in cool water… and allowed to air dry. Most industrial or group laundry facilities are likely to use hot water and tumble dry which may reduce the effectiveness of the products.”

Period underwear. Makers’ care pages mostly agree: rinse in cold water until it runs clear, leave out bleach and fabric softener, and hang or lay flat to dry. One maker says it can be machine dried on low if hanging is not possible. One maker says bleach and fabric softener “can decrease their performance and lifespan”. The full routine is in “How to wash period underwear, any brand”.

Reusable period pads. Here, makers disagree about stains. Here are three, side by side, in no order of preference:

  • One maker says: “Avoid frequent use of Hydrogen Peroxide and Oxygen bleach products.”
  • A second describes an overnight soak in cool water.
  • A third lists sun, a stain remover “or peroxide” for stains.

Makers disagree, so the instructions for the item in your hands come first. More is in “Reusable period pads, explained”.

Cups and discs are not fabric, so their care is different. It is in “Cleaning a cup or disc, between uses and between periods”.

Glossary · Wet bag

A sealable, waterproof bag for carrying used reusables until they can be washed. A National Defence guide calls it “a sanitary pouch or sealable waterproof bag”. Says who? National Defence.

Mattresses and sofas

This section is short, on purpose. The Editor could not confirm a textile-care authority’s method for mattresses or sofas. If your mattress or sofa came with care instructions, on a tag or from the maker, those come first. The safety box above applies to anything you use.

In reader forums, people describe blood on sofa cushions and furniture, and some keep hydrogen peroxide in more than one room for stains. These are readers’ habits, not tested advice.

What readers put on beds and sofas is in “Protecting your bed and sofa on heavy nights”.

If something goes wrong

  • If someone may have been harmed by a cleaning product: Health Canada says, “Call a poison centre or your health care provider right away.” It adds: “Tell the person who answers the phone what the product label says.”
  • If an item’s label is unclear: the maker of the item.

What this is not

This Column reports what care-label rules, Health Canada and makers say, and what readers describe doing. It did not test any method or product, and it does not rank them. It makes no claim that any method cleans, disinfects or removes a stain.

Next in this series: “Protecting your bed and sofa on heavy nights”.

This Column is general information, compiled by the Editor from the sources listed below. It is not medical advice, and the Editor is not a healthcare provider. For anything about your own health, talk to a healthcare provider.

No rush. We like reading slowly, one short piece at a time. The articles will wait for you.
