How to Remove Sunscreen Stains
Orange stains need acid, not detergent. The orange colour is avobenzone reacting with iron — treat it with lemon juice or citric acid. Do not tumble dry before treating.
Not all sunscreen stains are the same. Orange or rust-coloured marks and white chalky marks have completely different causes and need different treatments.
Types of Sunscreen Stain
Orange or rust-coloured stain (chemical sunscreen)
Cause: Avobenzone — the active UV-blocking ingredient in most chemical sunscreens — reacts with iron ions in tap water, sweat, and pool water to form an orange or rust-coloured iron complex. This is a similar reaction to rust (iron oxide) and is completely separate from the sunscreen's colour. Clear, white, or transparent chemical sunscreen can produce bright orange stains on fabric. The stain appears on swimwear, beach towels, shirt collars, and car seat fabrics.
Treatment: Citric acid (lemon juice, cream of tartar, or a commercial citric acid powder) dissolves the avobenzone-iron complex in the same way acid dissolves rust stains. Do NOT use standard laundry detergent as the primary treatment — it does not dissolve metal-organic complexes.
White, chalky, or powdery marks (mineral sunscreen)
Cause: Mineral (physical) sunscreens use titanium dioxide or zinc oxide as the active ingredient. These are fine powders that sit on the surface of the skin rather than absorbing into it. They transfer as white or chalky marks onto fabric. They do not react chemically with fabric.
Treatment: Brush off any dry powder first. Rinse with cold water. Most mineral sunscreen marks wash out easily with a normal wash. For fabric with a white cast, pre-treating with a small amount of washing-up liquid (dish soap) and cold water before washing removes any remaining residue.
Yellow or beige oily stain (sunscreen carrier oils)
Cause: All sunscreens contain carrier oils, emollients, and silicones that help the product spread on skin. These transfer to fabric and leave yellow or beige greasy marks — similar in nature to sebum (body oil) stains. The oily component is separate from the UV-filter chemistry.
Treatment: Treat the oily component with dish soap (a degreaser) applied directly to the stain before washing. Pre-treat for 10–15 minutes, then wash as normal.
Removing Orange Sunscreen Stains
- 1
Act before tumble drying — heat permanently sets this stain
The avobenzone-iron complex becomes extremely difficult to remove once set by dryer heat. Check swimwear and beach towels before putting them in the dryer. If you notice an orange stain on dry fabric that has already been through the dryer, treatment is still worth trying — but the stain may be permanent.
- 2
Rinse in cold water to remove any excess sunscreen
Rinse the stained area in cold water to remove loose sunscreen. Do not rub.
- 3
Apply citric acid solution to the orange stain
Choose one of: fresh lemon juice (highly effective, apply undiluted), white wine vinegar (milder acid — apply undiluted), cream of tartar paste (mix with a small amount of water), or a commercial citric acid powder dissolved in warm water. Apply directly to the orange stain and cover the entire area. The acid dissolves the avobenzone-iron complex.
- 4
Leave for 15–30 minutes
Allow the acid to work on the stain. For older or deeper stains, 30–60 minutes may be needed. Reapply if the area dries out.
- 5
Check progress and wash as normal
Rinse the treated area to check the stain. The orange should lighten significantly. Wash the item as normal with standard detergent. For swimwear, use a gentle or handwash setting — chlorine and heat degrade spandex (elastane) in swimwear over time.
- 6
Repeat if needed — check before tumble drying
Stubborn stains may need a second treatment cycle. Always check in good light before tumble drying. If orange remains, repeat the acid treatment before the next wash.
What to Avoid
Tumble drying before the stain is treated
Heat permanently bonds the avobenzone-iron complex to fabric fibres. This is the primary reason sunscreen orange stains become permanent — the garment went through a hot dryer before the stain was addressed.
Chlorine bleach
Chlorine bleach reacts with avobenzone and can worsen the orange colour rather than removing it. Never use chlorine bleach on chemical sunscreen stains.
Treating an orange stain with standard detergent only
Laundry detergent is designed to clean protein, fat, and some dye stains — it does not dissolve metal-organic compounds. Standard detergent alone is ineffective on the avobenzone-iron complex. You need acid.
Rubbing the stain
Rubbing drives the stain deeper into the fabric weave and can distort delicate fabrics like swimwear.
By Fabric
Most vulnerable to orange sunscreen stains as swimwear absorbs sunscreen from skin in the water. Cold water only — heat degrades elastane. Lemon juice or citric acid is safe. Do not wring. Air dry only.
Responds well to citric acid treatment. Check labels before using hot water wash after treatment.
Synthetic fibres can hold avobenzone stains deeply. Citric acid treatment is effective. Warm water (40°C) wash after treatment.
Similar to cotton. Citric acid treatment is safe. Linen can handle higher wash temperatures after treatment.
For white fabric, after the citric acid treatment, a follow-up oxygen bleach soak (Vanish / OxiClean) can remove any residual yellowing. Do not use chlorine bleach.
Prevention
- ✓Apply sunscreen and allow it to fully absorb (10–15 minutes) before dressing.
- ✓Use mineral sunscreen in situations where white marks are preferable to orange staining risk.
- ✓Rinse swimwear in cold fresh water after each use — this removes sunscreen, salt, and chlorine before they can set.
- ✓Check for sunscreen stains on light-coloured items before tumble drying.
- ✓Dark swimwear and towels hide sunscreen marks more than light colours — a practical consideration if staining is a recurring issue.
FAQ
Why does sunscreen leave orange stains on clothes?
The orange stain comes from avobenzone — the active UV-blocking ingredient in most chemical sunscreens — reacting with iron ions in tap water, sweat, or pool water. The reaction forms an orange iron-organic complex, similar in chemistry to rust. This happens even with clear or white sunscreen, and even when the sunscreen has been on for hours. Mineral sunscreens (zinc oxide, titanium dioxide) do not contain avobenzone and do not cause this reaction.
How do you get orange sunscreen stains out of clothes?
Apply an acid to dissolve the avobenzone-iron complex: fresh lemon juice, white wine vinegar, cream of tartar, or a citric acid solution. Leave for 15–30 minutes, then wash as normal. This is the same approach as removing rust stains from fabric. Do not use chlorine bleach — it can worsen the orange colour. Do not tumble dry before treating — heat permanently sets the stain.
Why do sunscreen stains turn orange after washing?
The sunscreen itself may not leave a visible mark immediately. The avobenzone reacts with iron in the water during washing or rinsing, creating the orange iron-organic compound in the fabric. This is why sunscreen stains often appear (or darken) after washing rather than immediately after sun exposure. If the garment is then tumble dried before the orange stain is noticed, the heat sets it permanently.
Does sunscreen wash out of swimwear?
The oily sunscreen carrier residue washes out with dish soap and a cool handwash. White marks from mineral sunscreen wash out easily. The orange/rust stains from chemical sunscreen (avobenzone) require acid treatment (lemon juice or citric acid) before washing — standard laundry detergent alone will not remove them. Rinse swimwear in cold water immediately after swimming to prevent stains from setting.
