Many thanks to my sister who recommended this Colour & Dirt Collector to me.
Just put a sheet into the washer and load all clothes together. Yes, I mean all coloured and dark coloured clothes, no separation is needed as this sheet will trap all the stains during the washing. I tried using my new purple shorts and the sheet turned all purple after the cycle, I checked the towels and all the white coloured tops, no colour transfer. 👍👍👍
30 sheets for only $10 will last me close to 4 months. Totally worth every penny. You can also get it any Cold Storage.
