Here's exactly how to wash canvas bags without shrinking or warping them: use cold water (20-30°C), a mild liquid detergent, turn the bag inside out, and air-dry it flat — never in a tumble dryer. Most plain cotton canvas bags can even go in the washing machine on a gentle cycle inside a mesh bag.
But waxed canvas, embroidered bags, and anything with leather trim need a gentler hand-wash approach — which is what we make and care about deeply here at RIVVIV. Get the method wrong, and you'll end up with a stiff, faded, misshapen rag.
So let's get it right.
What type of canvas bag are you dealing with? (And why it matters)
Canvas isn't one single fabric — it's a plain-woven cloth that comes in several types, and each one needs a different washing approach. Identifying your type first is the single most important step.
It's a tightly woven material, traditionally cotton or linen, built for durability. That tight weave is why canvas holds its shape so well — and why it reacts badly to heat.
Which type do you own?
Plain cotton canvas is the most common. Your everyday tote, your supermarket shopper, your book bag. Usually machine-washable if there's no fancy trim.
Waxed canvas has a coating that repels water. Never soak it. A damp cloth is as wet as it should ever get.
Printed canvas carries a design that may bleed. Test first, always.
Cotton-poly blend is washable but temperature-sensitive — the cotton component still shrinks in heat.
Not sure which you've got? Three quick tests.
Check the care label first. Then feel the texture — waxed canvas has a slightly slick, almost oily surface. Finally, the water droplet test: place one drop of water on the fabric. If it beads up and sits there, it's waxed. If it soaks in, it's plain cotton.
Now the hardware. Leather handles, brass zips, magnetic clasps — none of these can be submerged. Water rots leather and tarnishes brass.
Our own embroidered and plain canvas totes are made with this in mind, but the same rules apply whatever brand you own. And if yours has stitched detailing, our guide on how to clean embroidery covers the finer points.
Once you know your fabric type, it's time to prep — because rushing this next bit is how bags get wrecked.
What should you check before washing a canvas bag?
Before washing a canvas bag, empty every pocket, shake out debris, run a colourfastness test, and gather cold water plus a mild detergent. Skipping the prep is where most disasters begin.
Here's your preparation checklist:
- Check the care label
- Empty all pockets
- Shake out crumbs, sand, receipts
- Turn the bag upside down and pat the interior
- Run a cotton bud colourfastness test
- Fill a basin with cold water
- Have mild detergent ready
The colourfastness test is the one nobody bothers with.
Do it anyway.
Wet a cotton bud, press it firmly on a hidden spot — inside seam, base corner — for a full 10 seconds. Lift it. Any colour on the cotton bud?
Your dye isn't stable.
Colourfastness failure means one thing: hand-wash only, cold water, and wash the bag completely alone. No exceptions.
Some bags shouldn't be washed at all. If yours has a leather base, a suede lining, cardboard reinforcement in the bottom, or glued construction — stop. Water dissolves the glue and pulps the cardboard.
I learned that last one on a structured tote whose base turned to mush. More on that later.
Prep done? Good. If your bag passed the colourfastness test and has no leather or wax, hand-washing is the safest route for almost everyone.
How do you hand-wash a canvas bag step by step?
To wash canvas bags by hand: soak in cold water with mild detergent, gently agitate for 2-3 minutes, spot-brush dirty areas, rinse until clear, then press dry without wringing. It takes about ten minutes.
Follow these steps in order. And in full. Half-measures here are what cause those permanent creases.
① Fill a basin or sink with cold water, 20-30°C. Cool to the touch, never warm.
② Add 1 teaspoon of mild liquid detergent — Ecover Delicate or Woolite, both stocked in UK supermarkets. Swirl to dissolve.
③ Turn the bag inside out.
④ Submerge it and gently agitate for 2-3 minutes. Think swishing, not scrubbing.
⑤ Use a soft brush on dirty spots. An old toothbrush is perfect for handle stitching where grime collects.
⑥ Drain the soapy water.
⑦ Rinse under cold running water until no suds remain.
⑧ Press the bag gently between your palms or against the basin. Never wring.
Why does wringing matter so much? Twisting wet canvas crushes the woven fibre structure and forces permanent creases into the fabric. It also drags on the stitching until seams loosen.
I found this out the expensive way. Years ago I hand-washed a favourite navy tote, then wrung it out like a dishcloth because I was in a hurry. It dried with a diagonal crease across the front that never, ever came out. Ironing didn't fix it.
The bag looked permanently rumpled.
One bad twist. That's all it took.
Hand-washing is safest — but plenty of plain totes survive the machine perfectly well. If you know the settings.
Can you machine-wash a canvas bag safely?
Yes, you can machine wash a canvas tote bag safely — on a cold, gentle cycle with a low spin, turned inside out and placed inside a mesh laundry bag. But only if it's plain canvas with no delicate trim. That's the safe way to machine wash canvas tote bag fabrics — and honestly, how to wash canvas bags in a machine doesn't get simpler than that.
Here are the exact settings:
Cold cycle, 20-30°C. Gentle or delicate mode. Low spin — 600 rpm or lower. Bag turned inside out. Sealed inside a mesh laundry bag. Washed alone or with light-coloured towels for gentle cushioning.
Those numbers aren't optional. A hot wash or a fast spin will shrink and warp the fabric in a single cycle.
When should you never machine-wash? If the bag has leather handles, a wax coating, embroidered patches, or a cardboard base support. The spin cycle destroys all four.
Picture a canvas shopper with tan leather straps from a high-street shop. Machine wash that and the leather comes out stiff, cracked, and streaked. Unfixable.
Machine washing is convenient. But it's also the fastest way to ruin a bag you actually care about if the settings are wrong. When in doubt, hand-wash.
And if your bag has any stitched decoration, machine washing is off the table entirely — which brings us to the trickiest case.
How do you wash a canvas bag with embroidery on it?
Wash embroidered canvas bags by hand only, in cold water, with the embroidered side facing inward and the whole bag wrapped in a pillowcase. Machine agitation shreds stitching, so it's never an option here.
Embroidery adds three extra risks to plain canvas.
First, thread dyes bleed — red and dark threads especially. Second, stitched surfaces can snag on zips or other laundry. Third, the backing threads can loosen if the fabric gets yanked around.
So what changes in your routine?
Always run the colourfastness test directly on the embroidery threads first, not just the base fabric. The threads and the canvas can behave completely differently.
Then double up your protection: turn the bag inside out and wrap it in a pillowcase before washing. Belt and braces.
For RIVVIV embroidered bags specifically: embroidered side facing inward, absolutely no rubbing or brushing directly on the stitched areas, and flat-dry rather than hanging. Hanging drags the wet stitches downward and distorts the design.
Textile conservators take this even further — the V&A's textile collection shows just how carefully stitched pieces need handling to survive decades. Your tote isn't a museum artefact, but the principle holds.
For the complete method, read our full embroidery care guide.
Stitching aside, most bag-washing panic is really about one thing: stains. Let's tackle those properly.
How do you remove stains from a canvas bag?
Different stains need different treatments — oil stains lift with baking soda paste, water-based stains need cold water and vinegar, mud must dry first, and ink responds to rubbing alcohol. There's no single miracle method, but knowing how to clean a canvas bag by stain type makes it manageable.
Always test any treatment on a hidden spot first.
Say it with me.
Oily stains — food grease, cosmetics, sun cream. Mix a baking soda paste, 3 parts baking soda to 1 part water. Apply it, leave for 15 minutes, then brush it off. The baking soda absorbs the grease.
Then wash as normal. This is the classic way to clean canvas bag with baking soda — cheap, effective, and you already own the ingredients.
Picture a lunch bag with an olive oil splodge. Baking soda paste, quarter of an hour, brushed away — most of it lifts before you even reach the sink.
Water-based stains — coffee, tea, sweat. Rinse immediately under cold water. For set-in marks, dab with diluted white vinegar, one part vinegar to two parts water.
Mud and dirt — this one's counterintuitive. Let it dry completely first. Brush off the dry solids, then wipe with a damp cloth. Attack wet mud and you'll only smear it deeper into the weave.
Ink — dab rubbing alcohol on with a cotton pad. Dab, don't rub. Rubbing spreads the ink outward into a bigger mess.
Sometimes you can spot clean canvas bag fabrics entirely and skip full washing — kinder to the fabric and quicker for you.
Got the stain out? Now the part everyone rushes and regrets: drying.
How do you dry a canvas bag without ruining it?
Dry a canvas bag by laying it flat on a dry towel indoors, reshaping it to its original form, and air-drying out of direct sun. Never tumble dry, never hang, never bake it in a window.
Three things to never do:
Tumble dryer: shrinks canvas 10-15% and warps the shape. Direct sunlight: fades the colour and makes the fibres brittle. Hang drying: gravity stretches the wet, heavy fabric out of shape as it dries.
Why do people still do these things? Convenience. And the assumption that "it'll probably be fine."
Here's the correct method instead:
Lay the bag flat on a dry bath towel. Reshape it with your hands to its original form while it's still damp. Air-dry in a ventilated indoor space. Flip it once halfway through so both sides dry evenly.
When it's about half-dry, do this: stuff the bag with a clean, dry towel. The towel holds the interior shape and stops the bag collapsing into a crumpled heap.
This matters enormously for tote bags, which have no rigid structure of their own. A stuffed tote dries looking like a bag. An unstuffed one dries looking like a sad flannel.
Slow and flat wins. Patience here saves the whole job.
Now — the errors. Because knowing what wrecks a bag is half the battle.
What are the biggest mistakes people make when washing canvas bags?
The five biggest canvas bag washing mistakes are hot water, bleach, wringing, skipping the colourfastness test, and tumble drying — each one causing permanent, unfixable damage.
Ranked worst to least, with salvage advice for each:
① Hot water. Shrinks cotton canvas 10-15%. Already done it? Sadly, there's no reliable way to un-shrink cotton. Gently stretching it damp may recover a little, but manage your expectations.
② Bleach. Corrodes the fibres and can literally eat holes through the weave. If you've bleached it, rinse immediately and repeatedly in cold water to stop the reaction spreading.
③ Wringing. Permanent creases and loosened stitching. Reshape while damp and lay flat to dry — it won't fully reverse, but it limits the damage.
④ Skipping the colourfastness test. Dye bleeds across the whole bag. If it's already bleeding, rinse in cold water fast and toss in a Dr Beckmann Colour Catcher sheet, available at Boots and Amazon UK, to grab loose dye.
⑤ Tumble drying. Shrinkage plus hardware damage. No salvage — this is why we bang on about air-drying flat.
And here's my second confession. That structured tote with the cardboard base I mentioned earlier? I machine-washed it. On a warm cycle. Feeling clever.
The cardboard turned to porridge inside the fabric. The whole base sagged and lumped and never held a shape again. I'd skipped checking for internal reinforcement entirely.
Two ruined bags taught me this care-first mindset that conservators and museum collections rely on. Learn from my laundry crimes instead.

Frequently asked questions about washing canvas bags
Can I wash a canvas bag in the washing machine?
Yes — on a cold cycle, gentle setting, low spin, inside a mesh bag. Never machine-wash a bag with leather trim, wax coating, or embroidery. Those need hand-washing only.
How often should I wash my canvas bag?
Every 2-3 months for a daily-use bag. Between full washes, spot-clean marks as they happen — it's gentler on the fabric and keeps the bag looking fresh far longer.
Can canvas bags go in the tumble dryer?
No. Tumble drying shrinks and warps canvas and can damage any hardware. Always flat air-dry on a towel indoors, reshaped to its original form.
Will washing fade my canvas bag?
Cold water and turning the bag inside out largely prevents fading. The bigger fading risk is drying in direct sunlight, so keep it in the shade or indoors. This is the core of any good canvas bag care guide.
What detergent is best for canvas bags?
A mild liquid detergent like Ecover Delicate or Woolite, both sold in UK supermarkets. Avoid bleach and skip fabric softener — softener coats the fibres and dulls the fabric over time.
How do I clean a canvas bag without washing it?
Spot-clean with a baking soda paste for greasy marks, wipe the surface with a damp cloth, and air it out in the shade. For guidance recognised by UK craft authorities like the Embroiderers' Guild, gentle handling always beats aggressive cleaning.
Knowing how to wash canvas bags properly comes down to three habits: identify your fabric, test before you wash, and dry flat and slow. Do those and your bags last years, not months. Curious about the stitched detailing on your favourite tote? Read up on what embroidery actually is next.
