- Blot, don't rub.
- Test any remover on a hidden hem or seam first.
- Keep the bag out of the washer until the ink is gone.
- No dryer while any stain remains.
Highlighter on a bag is felt-tip dye, and the ink can spread through woven fabric the moment a damp cloth touches it. Bags are often a mix of outer fabric, lining, and trim, so the same mark can behave differently on each part. Fresh marks have the best chance with gentle work, but a stain pressed into a seam or left to dry may only partly lift.
Keep your damp cloth from pushing the ink through to the lining, because one wet press can spread it across the whole panel. When you're trying to get highlighter stains out of a backpack, a leather or suede trim needs its own gentler touch. If the mark has dried into a seam, stop wetting it and switch to a prewash stain remover spray or stick.

Step by step
Step 1 of 6
Check the tag first
Read the care label or tag first, and follow it over general advice. Work out which part of the bag the stain is on before anything wet touches it.
Step 2 of 6
Brush off the loose dirt
Use a dry, soft-bristled brush to lift loose dirt from the surface before you add any moisture. Brush gently in one direction so grit doesn't get pushed deeper into the fabric.
Careful. Don't brush leather or suede trim hard, and never wet it.
Step 3 of 6
Test a hidden hem or seam
Test your method on a small, hidden spot such as a hem or seam before you touch the stain itself. If dye transfers onto the cloth during the test, stick to gentle spot cleaning only.
Step 4 of 6
Dab the stain with soapy water
Dampen a clean cloth with cool water and a little mild soap. Gently pat or dab the stain, working from the edge toward the center, and turn to a clean part of the cloth as it picks up ink. A baking soda paste left on about 15 minutes is for cap sweat stains, so leave it out of this bag.
Careful. Rubbing spreads the ink across the fabric and pushes it deeper.
Step 5 of 6
Rinse out the soap
Pat again with a fresh damp cloth to lift the soap out of the fabric. Keep going until the cloth comes away clean and no soap is left behind.
Step 6 of 6
Blot dry and air dry
Blot with a dry microfiber towel or soft cloth to lift moisture and dirt, and don't rub it dry. Then let the bag air dry completely at room temperature, allowing at least 8 hours.
Tip. Check the seams and inside pockets before you call it dry.
Careful. Heat from a dryer or hair dryer can deform or damage the bag.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on bags, purses & backpacks, and its directions fit the steps above.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
If the stain was already dried or set, the method changes.
Old, dried or set-in stains →When to call a professional →How to tell it's working
Each pass should lift a little ink onto the cloth, and the stain should look paler after every round. When the cloth comes away with no color on it and the stain has faded out, the job is done.
What changes for yours
Adjust for your bags, purses & backpacks
Backpack
A backpack is usually a mix of fabric and trim, so first work out which part the stain sits on. Treat the fabric with the damp cloth steps, and leave any leather or suede trim out of the wet steps altogether.
Outer pockets and the front panel respond to the same cloth steps as the main body. Once the fabric is clean, let the whole bag air dry before you judge the result.
Leather or suede trim
Leather and suede trim changes the method more than anything else on a backpack. Keep it out of every wet step, and leave any stain on the trim to a light dry brush.
If the stain has spread onto the trim, don't try to lift it at home with the cloth steps. Let the trim dry on its own if it does get damp, then move on to the fabric.
Inside lining
Check the inside lining with a flashlight before you start, so you know how far the ink went. Then treat the lining with the same steps, keeping the cloth on the lining only.
Work even more slowly there, and swap to a clean part of the cloth often so the ink doesn't move onto the other side of the fabric. Let the lining dry fully before you close the bag, so no damp spots stay trapped inside.
Colored fabric
Colored fabric may not be colorfast, so a remedy that changes color can ruin the bag. Stick to cool water and a little mild soap, and skip peroxide and alcohol.
Test the mild soap on a hidden hem or seam first, and watch the cloth for any color coming off. If the cloth picks up color, stop there, since colorfast is not something you can assume.
Fabric you can't identify
If you can't tell what the fabric is, don't guess at a stronger method. Read the care label or tag and follow it first, and treat the bag with the cloth steps only.
If the tag is missing or unreadable, test the damp cloth on a hidden seam and go by the result. Stop and stick to spot cleaning if dye transfers onto the cloth.
Old, dried or set-in stains
An old highlighter stain that has had time to dry is harder, because the ink has settled into the fibers. Start by repeating the damp cloth steps, dampening a clean cloth with cool water and a little mild soap, then rinsing with a fresh damp cloth. Work a small section at a time and move to a clean part of the cloth often so you don't spread the ink around.
If the stain has been through the dryer or a wash, the ink may be set, and some felt-tip inks may be impossible to remove. Scrubbing harder or reaching for a stronger product on the bag itself risks damaging the material, and the stain may still not move.
If a faint mark remains after several rounds, that is a realistic outcome for an old felt-tip stain, so stop there rather than risk the fabric. Let the bag air dry fully between rounds, then check the spot in good light.
Vinegar, baking soda, peroxide and more
Do home remedies work on highlighter on bags, purses & backpacks?
Plenty of home remedies are passed around for ink, but most of them don't belong on a backpack. Cool water and a little mild soap are all a backpack needs, so the other remedies are best left alone.

What makes it worse
Mistakes to avoid
Don't launder before treating.
Machine washing is off limits for backpacks, and laundering can set the ink into the fabric. Treat the spot by hand first, using the steps above.
Don't use bleach or harsh cleaners.
Bleach and other harsh cleaning products can damage the material, and washing machine detergents are off limits for backpacks too. Cool water and a little mild soap are all the cleaning this stain needs.
Don't use too much dish soap.
A high concentration of dish soap can cause discoloration or strip natural oils from some materials. Keep the soap to a little, and rinse it out fully with a fresh damp cloth.
When to call a professional
If the stain is still visible after several rounds, a professional cleaner can take a look. Ask first how they clean, because some dry cleaners run items through a washing machine and dryer, which can set the ink.
Questions
Can I just rinse the stain under the tap?
Not as a first move. Running water and pressing can spread the ink, so use the damp cloth steps and blot instead.
Will the stain come out if it has already dried?
Sometimes, but dried ink is harder to lift. Repeat the damp cloth steps in small sections, and expect a faint mark on an old stain.
How long should the backpack air dry?
Allow at least 8 hours, and keep the bag at room temperature until it feels dry all the way through. Check the seams and inside pockets too, since they can stay damp after the outside feels dry.
What if I can't tell what the bag is made of?
Check the care label or tag and follow it first. If the fabric isn't listed, test a hidden hem or seam with the damp cloth, and stick to gentle spot cleaning if dye comes off onto the cloth.
What should I do if the ink spreads while I'm treating it?
Stop, blot with a dry cloth, and let the area rest. Then go back over it lightly with a fresh damp cloth, working from the outer edge toward the center so the mark doesn't grow.
Do shoe and cap methods work on a backpack?
No. Those are made for shoes and caps, so a backpack needs only a damp cloth and a little mild soap.
