A well-maintained gel blaster performs better, lasts longer, and saves you money on repairs and replacements. Whether you just bought your first ARP9 or you've been playing for years, this guide covers everything you need to keep your gel blaster in peak condition.
The good news: gel blaster maintenance is simple. It takes less than 10 minutes after each session if you follow the right steps.
Why Gel Blaster Maintenance Matters
Gel blasters fire water-based gel balls that leave moisture inside the barrel and internals. Over time, this moisture can cause:
- Barrel buildup that reduces accuracy and FPS
- Corrosion on metal components if left wet
- Gel ball residue clogging the feeding mechanism
- Battery degradation from improper storage
A quick post-session routine prevents all of these issues and keeps your blaster performing like new.
What You'll Need
- Clean, dry cloth or microfiber towel
- Cotton swabs or pipe cleaners
- Clean water (for barrel flush)
- Silicone lubricant spray (not WD-40)
- Battery charger
- Dry storage container or case
After Every Session: 5-Minute Routine
Step 1: Remove the Magazine & Clear the Chamber
Before doing anything else, remove the magazine and fire a few shots on semi-auto to clear any remaining gel balls from the chamber and barrel. Never store a gel blaster with gel balls inside — they will dry out, shrink, and potentially jam the mechanism.
Step 2: Flush the Barrel
Run a small amount of clean water through the barrel to clear any gel ball residue. You can do this by:
- Pointing the barrel downward and pouring a small amount of water through the feed port, then firing on semi-auto to push it through
- Using a cotton swab or pipe cleaner to gently wipe the inside of the barrel
Do not use hot water — room temperature or cool water only.
Step 3: Wipe Down the Exterior
Use a dry cloth to wipe down the entire exterior of the blaster. Pay attention to:
- The grip and trigger area (sweat and oils accumulate here)
- Any seams or joints where moisture can collect
- The magazine well and feed port
Step 4: Dry the Blaster
Leave the blaster in a dry, ventilated area for 15–30 minutes before storage. Do not store it while wet or damp. If you're in a humid environment, a dry cloth wipe-down is especially important.
Step 5: Charge or Store the Battery Properly
Battery care is one of the most overlooked aspects of gel blaster maintenance:
- If playing again soon: Charge the battery fully and store at room temperature
- If storing long-term: Store the battery at approximately 50% charge — not fully charged and not fully depleted
- Never leave a LiPo battery on the charger overnight or unattended
- Store batteries away from direct sunlight and heat sources
Monthly Maintenance: 15-Minute Deep Clean
Lubricate the O-Rings and Moving Parts
Apply a small amount of silicone lubricant to the O-rings (found around the cylinder and piston area) and any other moving parts. Silicone lubricant keeps seals flexible and prevents air leaks that reduce FPS.
Important: Use silicone-based lubricant only. Petroleum-based lubricants (like WD-40) will degrade rubber O-rings and damage your blaster over time.
Inspect the Magazine
Remove the magazine and check for:
- Dried gel ball residue in the feed lips or spring mechanism
- Cracks or damage to the magazine body
- Spring tension — it should push back firmly when compressed
Rinse the magazine with clean water, shake out excess moisture, and allow to dry completely before reuse.
Check All Screws and Connections
Vibration from full-auto fire can loosen screws over time. Do a quick check of all visible screws on the body, stock, and rail system. Tighten any that have worked loose — but don't overtighten, as this can strip threads in polymer bodies.
Inspect the Barrel
Look through the barrel toward a light source. The bore should be clear and smooth. If you see buildup or residue, use a cotton swab lightly dampened with clean water to clean it out. Allow to dry before use.
Gel Ball Storage & Preparation
Proper gel ball care is just as important as blaster maintenance:
Hydrating Gel Balls
- Soak dry gel balls in clean, room-temperature water for 3–4 hours minimum (overnight is ideal for maximum size)
- Use a ratio of approximately 1 teaspoon of dry gel balls per 500ml of water
- Fully hydrated gel balls should be 7–8mm in diameter — measure a few to confirm
- Do not over-soak — gel balls left in water for more than 24 hours can become too soft and break apart in the barrel
Storing Hydrated Gel Balls
- Store in a sealed container with a small amount of water to prevent drying
- Use within 1–2 days for best performance
- Keep out of direct sunlight — UV exposure degrades gel balls quickly
- Discard any gel balls that have dried out and re-shrunk — they will jam your blaster
Storing Dry Gel Balls
- Dry gel balls have an indefinite shelf life if stored correctly
- Keep in a cool, dry place away from moisture
- A sealed zip-lock bag or airtight container works perfectly
Long-Term Storage (1+ Months)
If you're storing your gel blaster for an extended period:
- Complete the full post-session cleaning routine
- Apply a light coat of silicone lubricant to all moving parts and O-rings
- Store the battery separately at approximately 50% charge
- Store the blaster in a hard case or padded bag to protect from dust and impact
- Keep in a cool, dry location away from direct sunlight
- Check the battery charge every 2–3 months and top up to 50% if needed
Troubleshooting Common Issues
| Problem | Likely Cause | Fix |
|---|---|---|
| Reduced FPS | Barrel buildup or O-ring wear | Flush barrel, lubricate O-rings |
| Gel balls jamming | Dried gel balls or magazine residue | Clear chamber, clean magazine, use fresh gel balls |
| Inconsistent firing | Low battery or dirty contacts | Charge battery, clean battery contacts |
| Motor not responding | Dead battery or loose connection | Check battery charge and wiring connections |
| Leaking air | Worn O-rings | Replace O-rings with silicone lubricant or new seals |
Maintenance Schedule Summary
| Frequency | Tasks |
|---|---|
| After every session | Clear chamber, flush barrel, wipe exterior, dry blaster, manage battery |
| Monthly | Lubricate O-rings, inspect magazine, check screws, inspect barrel |
| Long-term storage | Full clean, lubricate all parts, store battery at 50%, use protective case |

Frequently Asked Questions
Q: How often should I clean my gel blaster?
After every play session is ideal. At minimum, clear the chamber and wipe down the exterior. A full barrel flush should be done after every 2–3 sessions.
Q: Can I use WD-40 on my gel blaster?
No. WD-40 and other petroleum-based lubricants will degrade rubber O-rings and seals. Use silicone-based lubricant only.
Q: My gel blaster is shooting slower than usual. What's wrong?
The most common causes are a low battery, barrel buildup, or worn O-rings. Charge the battery first, then flush the barrel. If the issue persists, lubricate the O-rings.
Q: How long do gel blasters last with proper maintenance?
With regular maintenance, a quality electric gel blaster like the ARP9 or HK416 can last several years of regular use. The most common wear items are O-rings and batteries, both of which are inexpensive to replace.
Q: Can I leave gel balls in the magazine between sessions?
No. Always remove gel balls from the magazine between sessions. Gel balls left in the magazine will dry out, shrink, and can jam the feeding mechanism.
Final Thoughts
Gel blaster maintenance is straightforward and takes minimal time. A consistent post-session routine — clear the chamber, flush the barrel, wipe down, dry, and manage the battery — will keep your blaster performing at its best for years.
