For sunscreen stains, the important thing to understand is that not all SPF marks are the same. Some are primarily oils and waxes sitting within the fabric. Others involve mineral residues or chemical reactions that create staining long after the sunscreen itself has been washed away. Understanding the type of stain helps determine the right treatment.
Traditional cream sunscreens are often the simplest. These tend to leave darker greasy patches or oily shadows on fabric because they contain emollients, oils and waxes designed to sit on the skin. Marseille stain bars work particularly well here because soap naturally binds to oils, helping lift them from fibres so they can wash away. Wet the fabric, work the soap directly into the mark, leave for 10–30 minutes and wash normally. Soap-based washing-up liquid can also work for these oily marks for the same reason.
Mineral sunscreens, typically containing zinc oxide or titanium dioxide, behave slightly differently. These can leave white residue, chalky marks or dull patches on clothing, particularly darker fabrics. They may also contain oils alongside the mineral filters. Soap remains the best first treatment, with repeat applications where needed. Clay stain bars can also help where oily residues have built up alongside mineral deposits. See also this liquid for those that find it easier to handle or this large traditional bar, for dry clean fabrics pure clay.
Chemical sunscreens can sometimes create the most frustrating stains. Certain formulations, particularly those containing avobenzone, can leave yellow, orange, rust-coloured or pink marks, especially on white fabrics. These are not always simply sunscreen residue. Avobenzone can react with iron or minerals in hard water, creating staining that behaves more like a mineral deposit than an oil mark. Start with soap first to remove oils. If colour remains, citric acid treatment can help break down mineral-related staining then sunlight may also help naturally lighten residual marks.
Spray SPFs and dry oil formulations often spread further into fabric than traditional creams. These usually appear as darker greasy patches around collars, cuffs or swimwear. The same principle applies: treat the oils first. Soap-based stain treatment remains the strongest starting point, ideally before the item is heated in a tumble dryer, which can set staining more deeply.
Tinted facial SPFs can behave more like makeup than sunscreen. These products combine oils with pigments and iron oxides, creating beige, tan or foundation-like marks. Soap treatment should come first, followed by repeat treatment if necessary. Sodium Percarbonate may help with colour-safe /White fabrics where staining remains.
Where odours are present a Marseille soap bar with sodium bicarbonate can help, this is a de-odouriser and helps lift stubborn stains and greasy residue.
Older sunscreen stains can become more complex over time. Oils oxidise, minerals settle and heat from washing or drying can fix marks deeper into fibres. For these, multiple approaches may help — soap first, then percarbonate for organic discolouration or citric acid where mineral staining appears to be involved.
Washing Up liquid is often suggested for stains, and with good reason. This is effective on sunscreen stains because it is designed specifically to break down oils, fats and greasy residues, which is exactly what sunscreen contains. The important distinction is washing-up liquid is essentially a modern synthetic degreaser, whereas Marseille soap is a traditional soap-based cleaner. Both target oils they simply do it differently.
Our Washing Up Liquids are arguably better than many mainstream washing-up liquids because they already sit within our more traditional soap-based and eco aligned cleaning philosophy. Made with Coconut and Olive Oils, they are soap based and free from aggressive surfactants making them more suitable for textiles and delicate fabrics and those with allergies. Then they make perfect sense as an emergency or targeted pre-treatment too.

As a simple rule:
Soap removes oils.
Citric acid tackles mineral-related staining.
Sodium Percarbonate supports stubborn discolouration on whites.
Clay helps absorb oils and can be used on delicate and dry clean fabrics.
One final tip worth remembering: heat embeds stains so always best to use cool water. If a sunscreen stain remains after washing, avoid tumble drying as this will make it more difficult to remove.
