@Joe227 It's one of my pet hates to be honest. I do leave a packet of makeup remover wipes in the top drawer of the bathroom vanity, but not very many guests use them. The last guest who did, opened a new packet of 25 wipes, used 2 and then, took the rest of the packet with her!
We have had some really badly stained towels and washcloths, but after some research, I have found the perfect removal method for these types of stains.... and with a little scrubbing, it works every time for me.....
This method will suit any stain that is oil or grease based.... Prior to washing, directly and liberally apply non-Eco dishwashing detergent to the stain (it must be just the cheap and nasty brand of concentrated dishwashing liquid). Scrub and rub the stain onto itself, then dip into a small amount of HOT water and rub again.... by this stage most of the stain should be removed.
Then, when you put your towels in to the wash, add 3 squirts of the dishwashing liquid to your laundry detergent (for really bad stains you can also add a quarter of a cup of borax), and use white vinegar in place of fabric softener..... wash in HOT water!
Its really important to stop using Fabric Softener for your towels and sheets, as this puts a coating on them that actually attracts and absorbs oils, makeup etc!
I do like @Letti0 black make-up cloths though! I might have to try and sources some of these myself!
Cheers,
