To whiten most clothes, I'd start with the right amount of detergent, a whites-only load, the warmest water the care label allows and a scoop of oxygen bleach. Chlorine bleach is for the cottons and linens whose label shows the plain triangle.
Whitening is the job of lifting the grey or yellow cast that builds up on white fabric, with a bleach, a bluing rinse or a better wash routine. One warning before the tips. Health Canada says bleach reacts with ammonia and with acids, vinegar included, and the gases can be deadly. The safety notes near the end matter more than any whitening trick.
I write these guides for Merit Home Furniture from Duncan, on Vancouver Island. Merit Duncan, where I work, no longer carries appliances, as I mentioned in the wine cooler and beverage centre guide. So the washers named further down, like every appliance we still carry, are listed for our Campbell River and Port Alberni stores. The whitening steps work in any machine, old or new.
Why do white clothes turn yellow or grey?
White clothes turn grey mostly from dirt that never fully leaves the wash, and yellow mostly from oils and residue that build up and age in the fibres. Consumer Reports' laundry testers put grey whites down to soil moving from dirty clothes onto clean ones in the drum, along with too little detergent. Electrolux's support pages add hard water deposits, which leave a grey film.
Yellowing has a longer list. Electrolux names excess detergent and fabric softener, oxidation, deodorant marks, hard water and long storage. Sweat and skin oil also collect in collars, underarms and pillowcases. Maytag's help pages note that body soils can react with detergent and leave a white residue, most often on workout clothes. Warmer water and mixed cotton and synthetic loads make it worse.
Detergent dose cuts both ways. Too little leaves soil behind, Consumer Reports says, and too much builds up as a residue that greys whites, in Electrolux's words. Maytag points out that HE detergents come in 2x, 4x and 8x strengths, so a capful of one brand isn't a capful of another. Its advice is to follow the detergent maker's dose for the load size and soil level, and to put only HE detergent in an HE washer.
Winter tap water is the other culprit. Consumer Reports says detergent enzymes start working at about 60°F, and that cold tap water can sit near 40°F in colder parts of Canada. Maytag gives the same floor for dissolving detergent, and says undissolved clumps are more common with powder and in cold months. Consumer Reports found automatic temperature control, which tops up a cold fill with hot water, on every full-size front-loader it tested and on most top-loaders.
Hard water and dingy whites on the Island
Hard water is water carrying a lot of calcium and magnesium. The Regional District of Nanaimo's fact sheet on groundwater hardness says it cuts soap's ability to lather, and it uses the bands from the Guidelines for Canadian Drinking Water Quality.
| Hardness band | Calcium carbonate equivalent |
|---|---|
| Soft | Under 60 mg/L |
| Medium hard | 60 mg/L to under 120 mg/L |
| Hard | 120 mg/L to under 180 mg/L |
| Very hard | 180 mg/L or more |
The same fact sheet puts BC water, on average, at under 10 mg/L to 180 mg/L, and says groundwater tends to be harder than surface water. That matters to anyone on a private well. A municipal water report gives the number for a town tap, and a well test gives it for a well. Electrolux says to set the detergent dose by water hardness and soil level, using the detergent maker's chart.
How to whiten clothes with bleach, and what the care label allows
Chlorine bleach, the liquid household kind, is the strongest whitener in most laundry rooms, and the care label decides whether a garment can take it. The federal Guide to Apparel and Textile Care Symbols, from the Office of Consumer Affairs, shows bleaching as a triangle. The guide is kept for information only, since the national care labelling standard behind it was withdrawn in October 2017.
| Triangle on the label | What the federal guide says |
|---|---|
| Plain triangle | Use any bleach when needed |
| Triangle with two diagonal lines | Use only non-chlorine bleach when needed |
| Crossed-out triangle | Do not bleach |
For a normal load, Clorox Canada's directions call for 120 ml (1/2 cup) of its Disinfecting Liquid Bleach in a standard or HE washer, and less of its concentrated versions. It suggests adding the diluted bleach 5 minutes after the wash cycle starts. Its bleachability test is 2 teaspoons (10 ml) of bleach in 1/3 cup of water, with one drop on a hidden spot, rinsed after 5 minutes. If the colour holds, the item can take liquid bleach.
Clorox also says to keep bleach off wool, silk, mohair, leather, spandex and colours that run. Stretchy whites, from leggings to fitted sheets, are worth checking for spandex on the label.
Can you bleach off-white clothes?
Off-white, cream and ivory are colours in their own right, so the label settles it. With the plain triangle, Clorox's spot test on a hidden seam shows whether the shade will shift. With the striped triangle, oxygen bleach is the limit, and a crossed-out triangle rules out both.
How to whiten clothes without bleach
Whitening clothes without chlorine bleach usually starts with oxygen bleach, the powder sold as an oxi booster. Electrolux says detergents made for whites contain bleaching agents such as sodium percarbonate, which is an oxygen bleach. Consumer Reports calls powdered oxidizers like OxiClean milder than chlorine bleach and fine for most whites, cotton blends included. The striped triangle on a label allows them.
The household options below come from a washer maker and a bluing maker, with the amounts as they give them.
| Instead of chlorine | How much, and how |
|---|---|
| Hydrogen peroxide | One cup of 3% drugstore peroxide in the bleach dispenser, then a normal wash (Speed Queen) |
| Baking soda | A half cup, added once the washer fills. For dull cottons, a cup in a gallon of boiling water, taken off the heat, for a soak of a few hours (Speed Queen) |
| White vinegar | A half cup in the softener dispenser, or added when the rinse begins (Speed Queen) |
| Bluing | A few drops up to 1/4 teaspoon, diluted in a quart or more of cold water first (Mrs. Stewart's) |
| Sunshine | Line-dry whites outdoors; Consumer Reports credits the sun's bleaching power |
Bluing works differently from the rest. It adds a faint blue to white fabric, which the eye reads as whiter than a yellow cast. Mrs. Stewart's says undiluted bluing poured onto clothes can spot them, and that more than the recommended amount leaves a visible blue tint. Vinegar and chlorine bleach never go in the same load, since Health Canada lists vinegar among the acids that react with bleach.
Aspirin, lemon juice, borax and dishwasher detergent turn up in home whitening tips too. I couldn't find a Canadian authority backing them, and lemon juice is an acid that should never meet bleach.
Does Dawn dish soap make white clothes whiter?
Dish soap cuts grease, which is why it turns up in tips for oily collars. As a laundry detergent it's a poor fit. Maytag says to use only HE detergent in an HE washer, since the wrong detergent can leave undissolved clumps. Collar rings and other set-in marks are a stain-removal job more than a whitening one, and pretreating them before the wash helps.
Should white clothes be washed in hot or cold water?
Whites can go in the warmest water their label allows, which is often warmer than a coloured load can take. The federal care-symbol guide turns the dots inside the washtub symbol into maximum water temperatures.
| Dots in the washtub | Water no hotter than |
|---|---|
| One | 30°C, cool |
| Two | 40°C, warm |
| Three | 50°C, hot |
| Four | 60°C, very hot |
| Five | 70°C, extremely hot |
| Six | 95°C, near boil |
BC Hydro says around 80 per cent of a clothes washer's energy goes to heating the water, and it suggests cold washes as a simple saving. So hot water has a cost. I'd keep it for the loads that have greyed, such as towels, white sheets and pillowcases, and wash everyday whites warm or cold with a measured dose of detergent.
Washer makers build temperature into their whites settings too. One Electrolux front loader on Merit's site has a built-in water heater and a Sanitize temperature, and one Whirlpool top loader offers 5 temperatures.
Washer cycles that help whiten clothes
A washer can't bleach for you, but a presoak, a sanitize temperature or an extra rinse does a lot of the work. These five washers are listed on Merit Home Furniture's site with settings that suit whites. Prices are before applicable taxes, and each is carried at the store or stores named.
| Washer | Whitening settings, price, store |
|---|---|
| Whirlpool 5.4 cu. ft. top load, WTW5057LW | Presoak option that starts the wash after a 30-minute presoak, Deep Water Wash, a built-in faucet for pretreating, 5 temperatures; $949.99; Campbell River and Port Alberni |
| Maytag 4.4 cu. ft. top load, MVW4005SW | Soaking cycles that move straight into the wash, Deep Fill, Extra Rinse, a bleach dispenser; $999.99; Campbell River |
| Electrolux 5.2 cu. ft. front load, ELFW7437AW | Sanitize temperature, built-in water heater, Perfect Steam, StainTreat; $1,049.00; Campbell River and Port Alberni |
| Amana 5.0 cu. ft. front load, NFW5800HW | Sanitize with Oxi, a Presoak option, 4 wash temperatures; $949.99; Campbell River |
| LG 5.2 cu. ft. front load, WM3600HWA | Allergiene cycle, steam, ColdWash; $1,099.99; Port Alberni |
The Amana's Sanitize with Oxi cycle mixes detergent with an oxi additive, which makes it the closest thing on this list to a whitening program. The Whirlpool and Amana listings both suggest running the Clean Washer with affresh cycle every 30 washes, with a tablet or liquid chlorine bleach. Electrolux's support page asks for an empty maintenance wash at least once a month, at 60 to 90°C, because residue inside the drum ends up back on the clothes.
Every washer on our site sits in the washers collection, 114 listings on November 1, with dryers and washer-dryer pairs in the wider laundry collection. A washer with no store on its listing is a special order, and its page gives (250) 746-5527 as the number to call to order. For Courtenay and Comox, the valley's nearest Merit showroom is Campbell River.
How do you get dingy white clothes white again?
Getting dingy white clothes white again takes one reset wash, then habits that stop the build-up coming back. This is the order I'd follow, drawn from the makers and sources above.
- Read the labels. Pull out anything with a crossed-out or striped triangle, and anything with spandex, wool or silk.
- Wash whites on their own. Electrolux says colours can transfer dye and dull whites. Consumer Reports adds that very dirty items belong with other messy things. Pet hair comes off first, and the dry steps for dog hair go before the washer.
- Measure the detergent. Use the dose on the bottle for the load size, the soil and your water hardness, and leave the drum loose enough for clothes to tumble.
- Presoak in oxygen bleach. Use the washer's presoak or soak setting, or a tub, with the powder dissolved in the warmest water the label allows.
- Wash at the label's top temperature. For greyed towels that can take chlorine, Electrolux suggests a 2-hour soak in water with 100 to 200 ml of chlorine bleach. Then it's a machine wash at the highest temperature the label allows.
- Rinse well, then dry in the sun. An extra rinse clears leftover detergent, and a line outdoors adds the sun's bleaching.
- Clean the washer. Run the maker's clean cycle on schedule, so old residue doesn't settle back onto clean whites.
White sheets and pillowcases pick up the same oils as collars. When a set is past saving, Health Guard's white bamboo cotton sheet set is listed for Merit Duncan at $99.00 to $159.00 before applicable taxes. That sheet set isn't shipped; it's picked up free in Duncan or added to a furniture delivery.
Bleach safety, and when whitening clothes does more harm than good
Bleach safety comes first. Health Canada warns that bleach reacts with any cleaning product containing ammonia or an acid, vinegar included, and can give off toxic gases such as chloramine. Glass cleaners and toilet bowl cleaners are on its list. Its advice is never to mix any cleaning product with household bleach, to follow the label and to air the room out with open windows and a fan.
For a question about fumes or a swallowed laundry product, call the BC Drug and Poison Information Centre. It answers 24 hours a day at 1-800-567-8911 or 604-682-5050. HealthLink BC says to call 9-1-1 if the person is unconscious, not breathing or having a seizure.
Whitening can also go too far. Clorox keeps bleach off wool, silk and spandex, and Mrs. Stewart's warns that extra bluing tints whites blue. Some whites aren't meant for bleach at all: washing a waterproof mattress protector quotes Health Guard's care line, which rules it out.
If your whites have gone grey, I'd look at the detergent cup before buying any whitener. Measure it for a few weeks, wash whites on their own, and see where they land. And keep the bleach jug and the vinegar on different shelves.

Asking about washers for white clothes in Campbell River or Port Alberni
The washers in the table are carried at our Campbell River store, 1300 A Homewood Rd, and our Port Alberni store, 2935 Third Ave. Port Alberni is the shorter trip for anyone driving up from Cowichan. A call first tells you which models are set up, and nobody will follow you around while you look.
Each store sets its own terms, so ask about those on the call. For a washer listed as a special order, the line is (250) 746-5527.
Phone Port Alberni about washers, (250) 724-6644, or Campbell River on (250) 286-0868
