First, Patricia C. what is the name of the new product
whose active ingredient is sodium perforate?
Then, any chemist??? Does anyone know the difference or similarity of
Sodium carbonate Arm & Hammer Washing Soda),
Sodium Tetraborate decahydrate (20 Mule Team Borax)
It sounds as if the spot lightening technique you used is the paste &
dry method to whiten tide lines that we learned at FIT when Betty Kirke
taught classes. I have been recommending the stain lightening
procedure since 1990. It basically is:
Create a paste with warm to hot water to dissolve the crystals,
apply to the surface with a toothbrush, let dry & soak overnight,
scrape off with a spatula then rinse well.
Certain colors of certain fabrics do fade, usually pre-1905.
Just trying to see if sodium perborate is available here.
