كريم التارتار

I was skeptical about using it for cleaning, but mixing a bit with white vinegar made a thick paste that removed years of hard water stains from my faucet in minutes. The powder itself is so fine and odorless, it blends perfectly into my meringue recipes too.

The powder dissolves instantly when I whisk it into egg whites, and those stiff peaks held their shape perfectly through folding and baking. Also tried the vinegar paste trick on my shower glass and the hard water spots wiped away with almost no scrubbing.

My kitchen sink faucet had terrible white buildup, and this mixed with vinegar into a paste that cut through it like magic on the first try.
