Try rubbing one of the cleaners recommended for regular cleaning on stained area; leave on about an hour; rinse.
Use bleaching powder or its liquid form. No need to get any specific cleaner which are expensive just because of brand.
I recommend soft scrub! Also makes it smell clean and fresh.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
