Hello Donna,
Please call me Jeff (my father was Mr. Herman).
I know about Blue Magic, but I haven’t tried it. Regarding the
silicone, it should be fine for protecting silver, but I would
hesitate using it on anything that would come in contact with food,
such as flatware, since there may be toxic ingredients also left
behind. But here again, regardless of the protectant, any polish
that states it can polish aluminum, copper, and brass is going to be
WAY too abrasive for silver. Always consult my Silver Polish Abrasion
Ratings page, and especially what polishes not to use which can
found here: Silver Polish Reviews & Ratings, Best Silver Polishes & Abrasion Ratings
Happy Holiday’s to you, too!
Jeff Herman
