Gel Blaster Maintenance: Cleaning & Troubleshooting

A Gel Blaster is a mechanical device with moving parts, a motor, and a battery. Just like a bicycle or a toy car, it needs a little attention now and then. Good news: with a few simple steps, you can keep your Gel Blaster in top shape for years and prevent most malfunctions. In this guide, we explain step by step how to clean your Gel Blaster, troubleshoot issues, and store it properly.


Why is maintenance important?

Most complaints about Gel Blasters—such as a Blaster that no longer fires, malfunctions, or fires with reduced power—are not caused by a defect but by overdue maintenance or incorrect ammunition. Residual gel, moisture, and dust in the barrel or feeding system cause most problems.

With regular maintenance:

  • Prevent malfunctions such as jamming and misfires
  • Your Blaster will remain accurate as long as the barrel is clean
  • Your Blaster will last longer and you’ll save on repairs
  • Maintain your rate of fire and range just like on day one

It only takes a few minutes after a play session. That investment more than pays for itself.


How to clean your Gel Blaster in 5 steps

It’s best to clean your Blaster after every play session, or at least as soon as you notice gel residue left behind. All you need is a dry cloth, a cleaning stick (or thin brush), and possibly some silicone spray.

Step 1: Remove the magazine and the battery

First, remove the magazine and disconnect the battery. Always work on a Blaster that is disconnected from the power source. This prevents it from accidentally firing while you’re cleaning it.

Step 2: Empty the gearbox and hop-up

Fire the Blaster a few times (without gel balls) to ensure no loose balls remain in the feed system. Firing without ammunition ("dry firing") is permitted with Gel Blasters and helps clear out any debris.

Step 3: Clean the barrel

This is the most important step. Gel residue left in the barrel is the number one cause of poor accuracy and jams. Push a slightly damp cloth or a cleaning swab through the barrel until it is completely clean and dry. If necessary, rinse away stubborn residue with a little clean water and then dry thoroughly.

Step 4: Wipe down the exterior and the magazine

Wipe down the housing with a dry or slightly damp cloth. Also dry the inside of the magazine, as moisture in the magazine causes gel balls to stick together and jam.

Step 5: Lightly lubricate (optional)

Occasionally apply a small amount of silicone spray to the moving parts to ensure smooth operation. Note: Use only silicone oil. Never use petroleum-based oil (such as WD-40), as it will damage the rubber and plastic parts.


Why won't my Gel Blaster fire? The 7 most common causes

Has your Blaster suddenly stopped firing, or is it not reaching the speed it used to? In almost all cases, it’s due to one of these seven causes. Go through them from top to bottom.

Problem Most likely cause Solution
Doesn't shoot at all Empty or spare battery Fully charge the battery and check the connection
It clicks, but it doesn't work Gel balls that are too small, too old, or not properly soaked Use fresh pellets, soaked for 5 to 7 hours and completely submerged
Malfunction / Jam Broken gel balls in the barrel Clean the barrel and fire it a few times
Shoots weakly or short Battery almost dead or too old Replace or recharge the battery; use the correct mAh
We do not supply balls Moisture or dirt in the magazine Keep the warehouse dry and clean
Inaccurate Dirty barrel or hop-up Clean the barrel thoroughly
Makes a strange noise Dry or jammed gearbox Stop playing and have the gearbox checked

1. The battery is dead or not properly connected

By far the most common cause. Check that the battery is fully charged and securely connected. Always bring a spare battery for longer sessions.

2. The gel balls are too small, too old, or haven’t been soaked properly

This is by far the most common reason why your Blaster isn’t firing pellets. At the bottom of the magazine is a small motor that pumps the pellets up into the barrel. If the pellets are too small or too old, the motor can’t pick them up properly, and your Blaster will keep firing empty.

Old balls shrink and become soft. As a result, they burst more easily when fired and do not inflate properly. Therefore, always use fresh gel balls that have been soaked and stored exactly according to the instructions.

Here’s a handy trick to test if your BBs are too small or too old: load the magazine with BBs, hold down the trigger for a few seconds, and then turn the gun upside down. Does it suddenly start firing? If so, your BBs are too small or too old, and the motor can no longer pick them up. Time for fresh ammo.

3. There are broken gel balls in the barrel

Broken pellets leave a sticky residue. Clean the barrel (see the steps above) and fire the Blaster a few times to flush out any remaining debris.

4. The firepower decreases

Is your Blaster losing power as the game goes on? Then the battery is almost dead. Replace it and make sure you use the right capacity. With 1200 to 1800 mAh, you can easily play for 1 to 2 hours.

5. The magazine is not restocking properly

Moisture in the magazine is a silent killer: gel balls stick together and block the feed. Always make sure the magazine is completely dry inside after playing.

6. The Blaster is inaccurate

A dirty barrel disrupts the trajectory of the gel balls. A thorough cleaning usually resolves this immediately. Do you play at long range a lot? Pair this with a good scope or red dot sight.

7. Strange noises coming from the gearbox

If you hear grinding or rattling noises coming from the inside, stop playing immediately. Continuing to play may damage the gearbox. Have the Blaster inspected before continuing to play.


Soaking gel balls properly: the key to a trouble-free Blaster

Since the vast majority of malfunctions can be traced back to the wrong ammunition, this deserves a separate explanation. Fresh, well-soaked gel balls are only half the story.

  • Soaking time: let the balls soak in clean water for at least 5 hours and no more than 7 hours
  • Use enough water: use at least 1 liter of water per 1,000 balls
  • Completely submerged: the balls must remain completely submerged throughout the soaking process so that they absorb enough moisture
  • Always use fresh ones: soak only what you need and don’t use old balls that have been sitting around for days
  • Let them drain: only put dry, not wet balls in the magazine

Storage: Store soaked gel balls in a closed, airtight container. They will remain good for several days. Balls left exposed to the open air for an extended period will shrink: the moisture evaporates and the size decreases. Balls that are too small can no longer be properly pumped up by the motor at the bottom of the magazine, which leads to malfunctions.

Tip: Soak a fresh batch right before playing. This ensures your balls are the right size and you always have reliable ammunition on hand. View the full Gel Balls assortment.


Battery & LiPo maintenance

The battery is the heart of your Blaster. A little care will keep it in good shape longer and prevent you from running out of power in the middle of a game.

  • Always charge using a suitable balance charger
  • Never let the battery run completely dry; replace it as soon as the firing rate decreases
  • Store batteries at room temperature; do not leave them in direct sunlight or in a cold car.
  • Store a battery at half charge (around 50%) for extended periods.
  • Only use 11.1V (3S) if the manufacturer recommends it for your model

Storing your Gel Blaster for an extended period

If you won’t be using your Blaster for a while, for example during the winter, be sure to store it properly so it stays in top condition.

  • Make sure to clean and dry it thoroughly first, as moisture is the biggest enemy during storage
  • Remove the battery and store it separately, half-charged
  • Empty the magazine completely and don’t leave any gel balls inside
  • Store in a dry place at room temperature, away from direct sunlight

When should you replace parts?

Most parts last a long time, but wear and tear is just part of the deal. Replace them in time and your Blaster will stay as good as new:

  • Magazine: if the supply continues to be disrupted despite cleaning, check the magazines
  • Battery: if the playtime becomes significantly shorter than before
  • Attachments: You can easily replace worn or damaged attachments

Maintenance based on frequency of use
