- Keep the wipe light and move from the edges in.
- Check your tub's material before you pick a cleaner.
Henna stains in a bathtub show up as a brown, orange-brown or reddish-brown tint left by a plant-based dye. Acrylic, enameled cast iron and vitreous china each respond differently to cleaners, so the tub material decides how strong a cleaner you can use. Begin with a gentle lift and a spot test before anything stronger touches the surface.
Getting henna out of a tub is easiest with the gentlest method, so try that on a small hidden spot first. An acrylic tub needs a lighter touch than enameled cast iron, so check the surface before you commit. If the tint won't lift after a few tries, call a professional rather than pushing a stronger product.

Step by step
Step 1 of 6
Scrape up the paste
Use a rounded spoon to lift as much of the henna paste as you can, working gently so you don't press it into the finish. Then blot any liquid with a dry, white cloth. The white cloth shows you the color coming off without adding any of its own.
Step 2 of 6
Test the cleaner on a hidden spot
Pick an area the stain isn't on, such as a spot out of sight, and try the cleaner you plan to use there first. Check the finish once the test area is dry before you touch the stain.
Careful. Some cleaners change the finish of a bath, so the hidden-spot test is not optional.
Step 3 of 6
Wipe from the edges in
Dampen a soft sponge or cloth and wipe from the outer edge of the stain toward the center. Keep the pressure light and rinse the cloth often so it doesn't carry the color back across the tub. On vitreous china, use mild soap and warm water on the sponge instead of plain water.
Careful. Rubbing spreads the henna and can scuff the finish, so wipe and don't scrub.
Step 4 of 6
Use a general cleaner for heavy marks
If the stain is still heavy after wiping, apply a general-purpose cleaner listed for your tub's material to the mark only. Keep it off the rest of the finish, and use only the product you tested on the hidden spot.
Step 5 of 6
Rinse with water right away
Rinse the spot with plenty of water as soon as the cleaner is on it. Then wipe the rinse off with a clean cloth and repeat the wipe if the dye still shows.
Careful. Cleaners left to soak can damage the surface, so don't let them sit.
Step 6 of 6
Blot the tub dry
Dry the area with a clean cloth so no water or cleaner is left sitting on the finish. Check the spot in good light, since a faint tint is easy to miss in a dim bathroom. If a tint is left, the set-in section covers what to try next.
Tip. Use a flashlight held at a low angle to bring out a faint tint.

Best products for henna on bathtubs
Choose a general-purpose cleaner labeled for your tub's material, and only buy a cast-iron enamel cleaner if your tub is enameled cast iron. Read the label before you buy. Ammonia is off-limits on vitreous china, and don't use bleach on an airjet acrylic tub.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on bathtubs, 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
The paste should lift without smearing, and the cloth should stop picking up color. When the spot looks like the rest of the finish in good light, the job is done.
What changes for yours
Adjust for your bathtubs
Acrylic bathtub
On acrylic, the wipe with a soft, dampened sponge comes first, and a general-purpose cleaner labeled for acrylic is the only addition for a heavy mark. Abrasive cleansers are off the table here, since they damage the bath surface. Avoid aerosol cleaning products on acrylic, too.
Rinse with water after each use and dry with a soft cloth so the finish doesn't stay wet. If the spot still looks dull or scratched once it's clean, that's surface damage, and the repair route in the professional section applies.
Airjet acrylic bathtub
An airjet acrylic bath gets the same gentle wipe and rinse as a plain acrylic tub, so the steps barely change. What changes is what you keep out of it.
Keep full-strength bleach off the tub, since it can damage the surface. Full-strength ammonia is out for the same reason.
Use a cleaner labeled for acrylic, and rinse it off with water before you move to the next part of the tub. If you're unsure whether a product is safe for an airjet tub, skip it and stick to water and a soft cloth.
Enameled cast iron bathtub
On enameled cast iron, the same water-and-cloth wipe and general-purpose cleaner come first. Steel wool, wire brushes, and abrasive pads are off the table, because they can scratch the enamel.
For a stubborn mark, the set-in section covers the one abrasive that's allowed, used sparingly and always with water. Keep it to the spot itself, then rinse the area completely.
Vitreous china bathtub
On vitreous china, use mild soap and warm water on the sponge for the wipe, and rinse well afterward. Strong abrasive cleaners are a mistake here, because they scratch and dull the surface.
Ammonia cleaners can damage the finish, so skip them. The general-purpose cleaner is only for heavy marks, and only after the hidden-spot test.
Old, dried or set-in stains
Henna that has sat on the tub for a long time can be tougher than a fresh mark. On enameled cast iron or vitreous china, a soft abrasive cleaner used sparingly and always with water can help with a stubborn stain. Never use an abrasive on acrylic, since it damages the bath surface.
Dried paste is harder to lift, so soften it with a damp cloth, then scrape again. Then repeat the hidden-spot-tested wipe rather than adding more product.
If the tub still shows color after that, a faint tint is a realistic result. Stop before the finish starts to look dull, because more scrubbing can cost you more than the stain does.

Do home remedies work on henna on bathtubs?
A lot of home remedies get passed around for henna, but most were written for fabric. Here's how each remedy fits a bathtub, and why most of them should stay off the tub.

What makes it worse
Mistakes to avoid
Don't use solvents on your tub
Solvents are off the table for acrylic, enameled cast iron, and vitreous china alike. If a solvent is the only thing within reach, stop and use water and a soft cloth instead.
Don't let overspray reach the faucet
Cleaner overspray from the tub can land on the faucet. Rinse any overspray off nearby surfaces right away. Don't let ammonia, bleach, or acid products touch a PVD faucet finish.
Don't pick a cleaner by guessing the material
If you can't tell which material your tub is, use only water and a soft cloth until you know. Guessing is how a stain turns into a finish repair.
When to call a professional
If a dull or scratched acrylic finish is left after cleaning, cleaning won't fix it. Contact the manufacturer's customer service for repair. For enameled cast iron, improper care and cleaning can void the warranty, so check it before trying anything harsh.
Questions
Does henna stain a bathtub?
Yes. Henna is a plant-based coloring that leaves a brown, orange-brown, or reddish-brown tint, and that tint can show on bath surfaces. A fresh mark lifts most easily, so act on it soon.
Should I clean henna off the tub right away?
Yes. Scrape up the paste while it's still soft, because dried paste is harder to lift and tends to need more handling.
Blot any liquid with a dry, white cloth first, then move on to the wipe. Keep the cleaning light so the dye doesn't spread.
Is black henna dangerous to handle?
It can be. Black henna often contains PPD, a coal-tar hair dye that can cause dangerous skin reactions. Wear gloves while you clean, and wash any splash off your skin right away.
Will a faint tint be left after cleaning?
It can, especially if the henna sat for a while before you cleaned it. The set-in section covers the stronger treatments to try, but only on the tub materials that can take them.
Can I use mild soap instead of a cleaner?
Yes, on vitreous china, where mild soap and warm water is the wipe. On other tubs, start with water and a soft cloth.
How do I know what my bathtub is made of?
Check the tub's paperwork or the manufacturer's information first. If you still can't tell, use only water and a soft cloth until you know.
