Luckily, most powders, be they concealer, eyeshadow or blush will come out easily with a pre-wash treatment and normal washing.
Oils
Oils are best tackled by blotting up the excess, dusting in powder like talc to absorb the grease from the fabric, and some gentle brushing off.
If there’s still a notable mark, pre-treat it and wash with a biological washing powder.
Lipstick
The toughest of all to get rid of – lipstick stains can only really be tackled effectively with dry-cleaning liquid, and even that may not be a guarantee.
If it’s a small amount, make sure to remove all excess marks and you may have luck trying the ‘oil’ steps above.
