- Rinse under cold running water. Higher water pressure helps.
- Blot rather than rub.
- Don't let it dry on the plastic.
Sunscreen on plastic is usually an oily film, and some formulas also leave an orange, rust-colored part caused by avobenzone reacting with iron in hard water. The oily film lifts with soap and water, but the orange part is the one that lingers and needs extra steps. Plastic can't take heat or abrasive scrubbing, so keep the spot cool and go gently.
A sunscreen stain on plastic in a car interior often needs one more step after soap and water. Try a scouring cleanser only on a hidden edge first, since it can dull plastic. If the trace stays after a few light passes, stop rather than scrubbing harder, because plastic scratches easily.

5 steps
Step by step
Step 1 of 5
Brush off the excess
Start by brushing off any sunscreen sitting on the surface. Brushing first keeps you from smearing it when the water hits. Keep the strokes light.
Step 2 of 5
Rinse under cold water
Hold the plastic under cold running water to wash the loose lotion away. Higher water pressure helps move it off faster. Rinse until the surface feels free of residue.
Step 3 of 5
Wipe with mild dish soap
Dampen a soft lint-free cloth in warm water with a little mild dishwashing liquid. Blot the spot rather than rubbing, which keeps the oil from spreading across the plastic. Work from the edge of the stain toward the middle.
Tip. Switch to a clean section of cloth as it picks up sunscreen.
Step 4 of 5
Scrub only if needed
If the spot is still there after the wipe, scrub it gently with a plastic or nylon pad. Work only on the spot rather than the whole panel, and keep the pressure light.
Careful. No abrasive cleansers, and no pads other than plastic or nylon.
Step 5 of 5
Rinse, dry and check
Rinse the soap off with clean water and dry the plastic with a clean soft cloth. Look at the spot in good light: if it's gone, you're finished. If a faint orange tint remains, move on to the set-in treatment below.
Careful. Heat sets oily stains, so keep the spot away from heat until it is gone.

Best products for sunscreen on plastic & tupperware
Pick a mild liquid dishwashing detergent for the wipe. If you need a rust remover, choose a commercial one with clear label directions.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on plastic & tupperware, 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 spot is gone and the plastic feels smooth once the oily part has lifted. If a faint orange tint is left after the wipe and rinse, the rust part is still there, and it needs the set-in treatment.
What changes for yours
Adjust for your plastic & tupperware
Car interior plastic
Plastic trim, dashboards and door panels inside a car follow the same order as any plastic: brush off the excess, rinse with cold water, then wipe with mild dish soap and warm water. The oily part is handled like other oil stains, so the soap wipe does the lifting.
Keep the soapy cloth off the seats and upholstery, and treat those surfaces separately. For seats, the Car Seats and Leather guides cover the right cleaners for each material.
Exterior car plastic
Outside plastic, such as bumpers, trim or mirror housings, follows the same steps: brush off, rinse with cold water, then wipe with mild dish soap and warm water. Work the wipe over the plastic only, one section at a time.
Dish soap isn't safe on car paint, so keep the cloth off painted panels. If a set spot stays after the wipe, use the set-in soak described below on the plastic part only.
Old, dried or set-in stains
If the spot has been on the plastic a while, the first wipe may not clear it. Apply liquid dishwashing detergent and leave it on for 5-10 minutes, then rinse it off. Soak only the spot, not the surrounding plastic.
If the mark has dried or been left in the heat, the oily part is harder to lift, so repeat the soak once before going further. Wipe again with the soap and warm water, then rinse and dry the area.
An orange or rust-colored mark is the stubborn part. A commercial rust remover can work on it, but use it only per the label, wear heavy-duty rubber gloves, and test a hidden spot first. Rust is hard to lift, so a faint mark may remain even after this.

Do home remedies work on sunscreen on plastic & tupperware?
Most remedies in this area are for other stains or other materials, so most don't belong in this plastic method. Mild dishwashing liquid is the one that works here, and it's already in the steps. The others are a poor fit for plastic.

What makes it worse
Mistakes to avoid
Don't let it dry on the plastic
Dried sunscreen bonds more firmly to the surface and is harder to lift. Rinse and wipe it as soon as you notice it.
Don't reach for chlorine bleach
On an orange or rust-colored sunscreen mark, chlorine bleach sets the rust and makes it worse. Never mix it with vinegar or an acidic rust remover either, since that releases chlorine gas.
Don't use heat to lift it
Plastic lids and containers should never go on or under a flame, stovetop or broiler. If you microwave a lid, vent it or offset it so it doesn't warp.
When to call a professional
There's no set point at which a professional becomes necessary. If a rust mark is still there after the set-in treatment, stop rather than moving on to stronger products.
Questions
Does sunscreen stain plastic permanently?
Not usually when it's dealt with early. Fresh sunscreen lifts far more easily than a mark that has dried or been left in the heat. Start with the brush-off and cold rinse, and move on only if the spot is still there.
Why did my sunscreen turn orange on plastic?
Some sunscreens contain avobenzone, which can react with iron in hard water and leave orange, rust-colored marks. That part is harder to remove than the oily part. The set-in treatment is the method for it.
Is vinegar safe to use on sunscreen on plastic?
No, skip vinegar on sunscreen on plastic. Mild dishwashing liquid in warm water does the cleaning instead.
Can I use rubbing alcohol on sunscreen?
No, isopropyl alcohol is listed for marker on plastic lids, not sunscreen. Plastic can take solvents only with care, so test a hidden spot first if you're tempted.
Does heat make a sunscreen stain harder to remove?
Yes, heat is what sets the oily part. Keep the car out of the sun and the spot off hot surfaces until it's gone, and the cold rinse can start right away.
Can I clean a plastic phone case with the same method?
Remove the phone first, then wipe the case with a soft, slightly damp, lint-free cloth. Silicone cases need the gentlest approach, so stick to the wipe rather than anything stronger.
