Step 1: Turn Off Water
- Shut off the shower water

Step 2: Fill Bag with Vinegar
- Pour vinegar into the plastic bag
- Fill enough to submerge the shower head nozzles
Step 3: Attach Bag to Shower Head
- Place the bag over the shower head
- Secure with rubber band around the neck
- Make sure nozzles are fully submerged in vinegar
Step 4: Let Soak

When to Replace the Cartridge (Not Just Clean)
Cleaning the shower head helps with flow. But the cartridge still needs replacement:
Signs It’s Time to Replace:
- ⚠️ Chlorine smell returns
- ⚠️ Skin irritation returns
- ⚠️ Flow drops even after cleaning
- ⚠️ Discoloration of cartridge
Typical Cartridge Life:
- KDF-55 + Carbon: 4-6 months
- Calcium sulfite: 2-3 months
- Vitamin C: 2-3 months
Pro Tips
- ✅ Clean regularly — every 1-3 months
- ✅ Use distilled vinegar — works best
- ✅ Don’t use abrasive cleaners — they can scratch
- ✅ Check cartridge — while you’re cleaning
- ✅ Keep a spare cartridge — so you never run out
