Add-On: Citric Acid
Give your freshly etched pieces a quick glow-up. Citric acid is a gentle, low-odor way to remove oxide and heat tint from copper and brass after your salt-water etch—perfect for home studios and classrooms.
What you’re getting
Pre-measured 3 tablespoon packs in labeled sachets.
How to use (pickle bath)
In a glass or plastic container, dissolve 1 tbsp citric acid in 1 cup hot water (≈ 1:16 by weight).
Submerge your etched metal (avoid steel tools).
Soak 5–10 minutes, agitating occasionally, until bright.
Rinse well, dry, and proceed to finishing (patina, seal, etc.).
Tips
Warm solution works faster; refresh if it gets cloudy or slow.
Use plastic/titanium/copper tongs—skip steel in the bath.
Store mixed solution covered and clearly labeled; refresh as needed.
Safety & disposal
Do not ingest. Food-grade material used for metal cleaning only.
Wear gloves/eye protection; avoid contact with eyes and skin.
Never mix with bleach or cleaners containing hypochlorite.
To dispose: slowly neutralize with baking soda until fizzing stops, dilute with plenty of water, then drain per local guidance.
