Curry stain, what’s your secret?

Edit : two washes with oxyclean did the trick

Hello there,

What's your secret to remove curry stains from white shirts? I ate Thai food and stuff happens.

I tried Dr. Beckmann Stain Devils FAT & SAUCES 食用油/カレー/ トマトソース/醤油用

I tried お洗濯の前に 簡単ひと手間 きこみヘッド とん とん NANOX シミ 食べこぼし ஒ 蛍光剤無配合で色柄ものにも安心 「食べこぼしのシミ・血液 までスッキリ LION

I tried

ドンドン ぬって みるみる きれいになる 染み抜き 衣類のシミに スポッとる! SPO-TC

Nothing works.

I bought oxiclean and it will arrive tomorrow but if it doesn't work I'm out of ideas…..
The shirt is 100% cotton.

Thanks
