Baking soda mixed with vinegar will help, but it does require scrubbing!
Try vinegar or lemon juice, they will probably require a bit of elbow grease too.
Bicarbonate soda and vinegar. If you mix the two with a bit of lemon juice, water it down. Fill a spray trigger bottle, spray , walk away.
Wait 10 - 20 minutes come back with the spray and a scrubbing brush. You will have to scrub if you don't want to use chemicals. Please remember to rinse!
So many people forget to rinse and make later jobs harder on themselves.
My chemistry lecturer once told me that the best thing you could use is just plain vinegar. Anything more than that was a waste of money according to him.
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.
