GOLF SIMULATOR MAINTENANCE IS THE PART nobody talks about when you are researching which system to buy. You spend weeks comparing launch monitor accuracy and impact screen materials, then once the simulator is installed, you use it constantly without thinking about upkeep. Three years later the screen has permanent dark streaks, the hitting mat has a bare patch where your left foot lands, and your launch monitor is reading 15 yards short because the camera drifted slightly after the last room rearrangement.

Proper maintenance extends the life of every component and keeps your shot data accurate. Here is what to do and how often.

Impact Screen Maintenance

The impact screen takes more abuse than any other component. Every shot that does not stop in a net hits the screen at high speed. The good news: modern impact screens are built to take this. The bad news: they still accumulate dirt, ball marks, and eventually small tears if neglected.

Monthly cleaning: Mix a small amount of dish soap (not degreaser) in warm water. Apply with a soft microfiber cloth using circular motions. Focus on the center impact zone where ball marks accumulate. Rinse the cloth and wipe again with clean water. Let the screen air dry completely before projecting onto it. Never use bleach, ammonia-based cleaners, or abrasive sponges; these break down the screen fiber over time.

Seasonal inspection: Look for small holes or tears, particularly in the center impact zone. Minor holes can be repaired with screen repair tape available from golf simulator retailers. Large tears or multiple holes mean the screen is approaching end of life. Catching small damage early prevents it from spreading into a full replacement situation.

UV protection: If your simulator is in a room with natural light, cover the screen when not in use. UV exposure bleaches the material and weakens it over time. A simple canvas cover or even a bedsheet works.

Hitting Mat Maintenance

Hitting mats wear unevenly because you always address the ball from the same position. The area where your left foot lands (for right-handers) and the ball position area take the most stress. Most mats last 2 to 5 years under regular home use before the turf fibers in the high-traffic areas become compressed enough to affect your stance.

Quarterly rotation: If your mat design allows it, rotate it 180 degrees so wear is distributed across the full surface rather than concentrated in one spot. Not all mats can be rotated (some have a specific face angle alignment), but those that can will last significantly longer.

Brush the turf fibers: Use a stiff brush to raise compressed fibers back up every few months. This restores the feel of the mat surface and is especially important in the impact zone.

Check the rubber base: Inspect the underside annually. If the rubber base is cracking or delaminating from the turf layer, the mat is approaching replacement. A mat with a failing base can slip during the swing, which is a safety issue.

Launch Monitor Calibration and Care

Launch monitor accuracy depends on consistent positioning. Even a 1-degree shift in camera angle (for optical systems) or alignment from the target line (for radar systems) affects your data.

Camera-based systems (SkyTrak, Foresight GC3, Full Swing Kit): Mark the floor position of the unit with tape when you first set it up. After any move or cleaning session, return the unit to its marked position. Run the built-in calibration routine (most modern systems have one) every 3 to 6 months or whenever you notice data inconsistencies such as carry distances that do not match your outdoor baseline.

Radar-based systems (Garmin R10, Rapsodo MLM2PRO, Bushnell Launch Pro): These are more tolerant of minor positioning changes but still benefit from consistent placement relative to the ball position. Keep the unit clean and free from dust on the radar face; accumulated dust can cause subtle inaccuracies in low-speed shots.

Software updates: Check for firmware and software updates quarterly. Manufacturers release accuracy improvements and bug fixes regularly. Running outdated firmware on a launch monitor can leave you with data quality that has been superseded by available improvements.

Projector and Screen Alignment

Projector alignment drifts over time, particularly if the projector is ceiling-mounted and the mount settles slightly. Check your screen image quarterly: edges should align with the screen frame, and the image should not show keystone distortion. Most projectors have keystone correction in their menu. For persistent alignment drift, check that the ceiling mount is still firmly anchored.

Clean the projector lens every 6 months with a camera-lens microfiber cloth. Dust on the lens reduces image sharpness and contrast, making the course less legible, particularly for shot landing zone markers.

Year-End Full Check

Once a year, run a complete audit of your setup: check all cable connections (loose HDMI or USB cables cause random disconnects during sessions), inspect the netting behind the screen for tears or sagging, test all software licenses are current, and run a full calibration with known-distance outdoor shots to verify your launch monitor data matches real-world performance. This annual check catches degradation before it affects your practice quality.
