Can you remove [common Bangkok stain] from my clothes?

Yes for ~80% of recent (under 1 month) sweat stains, ~40% for stains older than 6 months, near-0% for stains that have been chlorine-bleached previously (that combination is permanent). Our protocol: 30-minute oxygen-bleach soak before the regular wash, repeat soak if the wet collar still shows yellowing. We don't use chlorine bleach because it reacts with sweat sulphur to create more yellow staining. Bring shirts in early — Bangkok humidity makes the yellowing accelerate.

Yes — about 90% success on stains under 24h old, ~60% if the shirt has been worn or dried since. Protocol: dish-soap pre-treat directly on the stain, leave 10 minutes, hot wash. The longer Bangkok food oils sit on cotton in heat, the more they bond with fibres. If you spilled tom yum at lunch and book pickup the same evening, we usually save the shirt. If you wore the shirt for another week with the stain set in, the odds drop sharply.

Yes — about 95% success if blood is rinsed in cold water within 1 hour of the stain happening, dropping to ~50% if the blood has been put through a hot wash or dryer. Hot water cooks the protein and bonds it permanently with the fabric — never put a bloodstained item in hot water before professional treatment. Our protocol: cold-water enzyme soak, hydrogen peroxide on white cotton only, enzyme cleaner on coloured fabric. Send in as soon as possible, don't try to wash first at home.

Yes — almost always, 95% success rate if treated within 24h. The coloured powder used during Songkran (April 13–15) is fugitive dye designed to wash out. The catch: don't put the shirt through a hot wash first — the heat sets the dye permanently. Cold rinse, then send to us, and we oxygen-bleach soak before regular wash. After 48–72h the dye starts to bond with cotton and odds drop. Songkran turnaround is slower than usual at every Bangkok laundry — book pickup as soon as the festival ends.

Mostly no. On cotton white t-shirts, alcohol-based pre-treatment removes about 30% of fresh permanent marker stains and 0% of stains older than a few days. On synthetic blends (polyester) we cannot remove marker at all without dissolving the fabric. We're honest about this before processing — if you tell us at booking 'there's permanent marker on this shirt' we WhatsApp you with realistic odds before charging the wash. For most marker stains the recommendation is 'wear it as a paint shirt now', not 'pay for cleaning'.

No. Once chlorine bleach has removed dye from a coloured fabric, the dye is gone — not 'damaged', removed. The only fix is to dye-overdye the entire garment or replace it. We don't touch bleach-damaged garments and we don't charge for assessment. We'll tell you honestly that nothing can be done. Sometimes a customer brings in a 'mystery yellow stain' that's actually been bleached — same situation, the original stain may be invisible but the bleach reaction is permanent.

Three categories we decline to attempt: (1) stains on garments where the customer has already used chlorine bleach and the result is now permanent yellow — additional treatment makes it worse. (2) Self-tanner that has been on cotton more than 48 hours — DHA bonds permanently and our chemistry won't reverse it. (3) Mystery stains on dry-clean-only labels where we can't identify what we're treating — wrong solvent on silk or wool can dissolve the fabric. In all three cases we tell you upfront, return the garment uncleaned, and you can choose to send it to a specialty restoration service or accept the loss.
