Before Cleaning

[checklist] * Turn off the dash cam or switch off the vehicle ignition * Disconnect the dash cam from its power source * Allow the device to cool if it feels hot * Make sure your hands and cleaning materials are dry enough to avoid dripping liquid [/checklist] [warning] Never spray cleaning liquid directly onto the dash cam, lens, ports, buttons, or connectors. [/warning]

Powering the device down before handling it also reduces the chance of interrupting an active recording while the camera is being moved or disconnected.

Cleaning Materials

Use soft materials that will not scratch the lens or damage the housing.

Clean microfiber cloth suitable for lenses or glasses.
Soft lens-cleaning tissue if needed.
Lens-cleaning solution or a very small amount of distilled water for stubborn marks.
Dry cotton swabs for corners and seams.
Small soft brush or manual blower for loose dust.
A small amount of mild, non-ammonia cleaner suitable for plastic, if required for the body.

[dosdonts] Do: Start with a dry cloth, brush, or blower before using any moisture Do: Apply any cleaning liquid to the cloth rather than directly to the camera Dont: Use paper towels or rough cloths on the lens or screen Dont: Use acetone, harsh solvents, or ammonia-based cleaner on the dash cam Dont: Use sharp objects to scrape dirt or adhesive from the device [/dosdonts]

Clean the Lens

The lens has the greatest direct effect on recorded image clarity. Dust, fingerprints, interior residue, and haze can contribute to blurry footage, glare, halos, or light streaks.

[step] 1. Remove loose dust with a soft brush or manual blower before wiping the lens 2. Wipe gently with a clean, dry microfiber cloth using light circular movements 3. For stubborn marks, lightly dampen one part of the cloth with lens-cleaning solution or distilled water 4. Wipe the lens gently, then dry it immediately with a clean section of the cloth 5. Check the lens from different angles under reflected light for remaining fingerprints or streaks [/step]

Suggested Cleaning Checks

In dusty or heavy-use conditions, inspect the lens about once a week.
For normal city driving, checking every two to four weeks may be sufficient.
Check it again after long trips, dusty or stormy conditions, or whenever the lens has been touched.

[tip] If night recordings suddenly show more flare or halos around lights, inspect both the dash cam lens and the inside of the windshield for smudges. [/tip]

Body, Buttons, and Ports

Dust around the housing can collect in seams, buttons, and connection areas over time.

Wipe the housing with a dry microfiber cloth.
Use a soft brush on textured plastic and narrow grooves.
For visible stains, use a slightly dampened cloth with water or a mild cleaner suitable for plastic, then dry the surface promptly.
Use a dry cotton swab around buttons and seams.
Use a manual blower gently around ports or small gaps if loose dust is present.
Avoid pressing or forcing debris deeper into openings.

Mount and Windshield

A clean mounting area helps the 70Mai Dash Cam remain stable and reduces movement in recorded video.

Windshield Area

Clean the inside of the windshield around the camera using a suitable glass cloth or non-ammonia glass cleaner.
Allow the glass to dry completely before attaching or adjusting the mount.

Adhesive Mount

If the adhesive remains secure, clean around it rather than disturbing it unnecessarily.
If the camera no longer stays firmly attached, the adhesive pad may need replacement.
Before fitting a replacement pad, make sure the glass is clean, dry, and free from dust or oily residue.

Suction Mount, If Used

Wipe the suction surface gently with a damp cloth.
Allow excess moisture to dry before reattaching it.
Press the mount firmly against clean glass for several seconds to establish a secure hold.

Check the Camera Angle

After cleaning or remounting, verify the view before relying on the camera again.

[checklist] * Camera has a clear, unobstructed view through the windshield * Rearview mirror or other objects do not block the recording area * Camera is not aimed excessively toward the sky * A small portion of the vehicle hood may remain visible near the bottom of the frame where suitable * Mount feels secure and the camera does not shake noticeably [/checklist] [note] The ideal framing can vary with the vehicle, mounting position, and 70Mai Dash Cam model. Use the live camera view when available to confirm the final angle. [/note]

Power Cable and Connections

Loose, pinched, or heavily bent power cables can contribute to unstable power delivery.

Cable Routing

Keep the cable neatly routed along the windshield edge, roof liner, or suitable trim area.
Check for knots, sharp bends, pinched sections, or visible wear.
Keep wiring away from the steering wheel, pedals, and other areas where it may be pulled or interfere with vehicle controls.

Connector Care

[step] 1. Disconnect the cable from the dash cam and its power source 2. Inspect the plugs and connection areas for visible dust, residue, or corrosion 3. Remove loose dust with a dry cotton swab or soft brush 4. Reconnect the cable securely after the area is clean and dry [/step] [warning] Do not place liquids inside power connectors or ports. If a hardwire installation has loose, damaged, or exposed electrical connections, have the installation checked appropriately rather than altering vehicle wiring during routine cleaning. [/warning]

microSD Card Care

Continuous video recording places repeated write cycles on the microSD card. Storage condition is therefore an important part of dash cam maintenance.

Use a reputable high-endurance microSD card intended for frequent video recording.
Use a card with a speed capability suitable for the recording demands of your dash cam model.
Avoid low-quality or unbranded cards when recording reliability is important.

Formatting

If periodic formatting is part of your maintenance routine, use the dash cam's available formatting function where supported. Formatting deletes stored recordings, so save any clips you need before proceeding.

For heavy daily recording, checking or formatting the card every two to four weeks can be used as a practical maintenance interval.
For lighter driving, an interval of roughly one to two months may be sufficient.

[warning] Formatting erases recordings stored on the card. Preserve any important footage before formatting. [/warning]

When to Consider a New Card

Recording-related card messages appear repeatedly.
Expected clips are missing from the recording timeline.
The camera repeatedly restarts while recording and the storage card is suspected.
The card has been used for heavy continuous recording for an extended period.

Endurance cards still wear over time. Depending on recording intensity and card condition, replacement after roughly one to two years can be considered as preventive maintenance rather than a fixed requirement.

Firmware and Device Performance

Software maintenance can also be part of routine care. When your 70Mai Dash Cam model provides firmware updates through its companion app, check for updates periodically rather than changing software unnecessarily.

Power on the dash cam before starting the update process.
Connect to the camera as required by the companion app, including its local Wi-Fi connection where applicable.
Follow the update flow shown for your particular model and app version.
Keep the dash cam connected to stable power until the update process has completed.

Firmware updates may include changes to camera processing, stability, parking-related functions, motion-related behavior, or app connectivity, depending on the model and update.

[warning] Avoid disconnecting power while a firmware update is in progress. [/warning]

Heat and Sun Exposure

A dash cam regularly experiences sunlight and high cabin temperatures. Reducing unnecessary heat exposure can help with long-term care.

Where practical, position the camera so the rearview mirror provides some shade without blocking the lens.
Avoid a mounting position that receives unnecessary direct sunlight for prolonged periods when another suitable position is available.
Do not cover the dash cam with cloth, ornaments, or other objects.
Keep normal cabin airflow paths unobstructed.
Park in shade or use a windshield sunshade when practical in very hot conditions.
If the camera feels extremely hot, allow it to cool before cleaning, handling extensively, or changing settings.

Long-Term Storage

If the vehicle or dash cam will not be used for an extended period, prepare it for storage rather than leaving it powered unnecessarily.

[step] 1. Turn off and disconnect the dash cam from power 2. Remove the microSD card if the camera will be stored separately 3. Keep the card in a dry, protected location 4. If removing the camera, store it in a cool, dry place away from direct sunlight and moisture 5. Avoid leaving the removed device in an excessively hot, closed vehicle for long periods [/step]

Before Using It Again

[checklist] * Mount is still secure * Camera angle is correct * Power cable and connectors are in good condition * microSD card is recognized and ready for recording * Important card contents have been saved before any planned formatting * Available firmware updates have been checked if appropriate [/checklist]

Routine Care Schedule

[reference] Title: Weekly or Every Two Weeks Text: Check the lens, camera angle, mount stability, and loose or dangling cables. Title: Monthly Text: Clean the nearby windshield, inspect the mount, review microSD card condition, and check for available software updates where appropriate. Title: Every 6–12 Months Text: Perform a deeper exterior clean, inspect power cables and connectors for wear, and review whether the storage card still performs reliably. [/reference]
