A sparkling clean stainless steel housing isn’t just about looks—it prevents bacterial growth and maintains water purity. Forget harsh chemicals! Food-grade citric acid is the safest, most effective solution for removing scale, stains, and buildup. Here’s how to do it right.
Why Citric Acid? The Science Behind It
✔ Non-Toxic & Food-Safe: Unlike vinegar or CLR, leaves no chemical residue
✔ 3X Faster Descaling: Breaks down calcium/lime deposits at lower concentrations
✔ Passivates Stainless Steel: Restores the protective chromium oxide layer
Bonus: Also removes iron stains from well water without scratching
Method 1: The 10-Minute Spot Clean
For light maintenance (monthly):
Mix 1 tbsp citric acid with 1 cup warm water
Dip a microfiber cloth and wipe housing exterior
Rinse, then dry with a clean towel
Best for:
• Fingerprint smudges
• Water spots
• Dust accumulation
Method 2: The Deep Soak (For Heavy Scale)
For interior/exterior crusty buildup:
Fill a basin with 1 gallon hot water + ½ cup citric acid
Submerge disassembled housing for 20-30 mins
Scrub stubborn areas with a nylon brush (never steel wool!)
Triple-rinse before reassembly
Removes:
• White lime crust
• Rust-colored iron deposits
• Mineralized biofilm
Method 3: The Circulation Cleanse (Plumbed Systems)
For whole-system descaling:
Mix 3 tbsp citric acid per quart of water in the tank
Run through system for 5 minutes, then let sit 1 hour
Flush with 2x system capacity of clean water
Ideal for:
• Under-sink RO systems
• Whole-house filters
• Commercial water stations
Pro Maintenance Tips
→ Always hand-dry after cleaning to prevent water marks
→ For brushed stainless, wipe with the grain
→ Store citric acid solution in a glass spray bottle for quick touch-ups
