I hope you found a solution for your tablecloths.

I would use diluted bleach, or Napisan or Vanish.

I am going to try napisan on a range of things to see if it works.

Don’t use bleach, it will destroy them! Try a spraying with Napisan and then soaking them in Napisan. Make a paste of Napisan and water and apply, leave overnight and wash. You may need to repeat one or more of the above

I use vanish and make it into a paste put it on the stain and leave it for a few hours then I soak it in bleach overnight then put it in the wash. This method gets all my stains out good luck x

If they’re not too delicate, I’d make a paste from Nappysan and dab it on the stain. Let stand for a few hours and keep adding some more paste to it as needed to keep it moist. Then wash with nappysan and line dry outside on a sunny day to get the sun to help bleach it white too.

Theres the sard liquid that comes with a little agitating head on the end of it, pop some of that on and let it sit for a few minutes before washing. I’d also pop some napisan or sard in as a pre wash.

Martha Gardiner produced a book, google her – she has amazing tips for all stains

Also, a good quality soaker is what I use for the process.

I would use nappy-san in a soak and wash!

Maybe a good soak in your brand of soaker. I have done this, repeated the process several times and it helped.
