Step-by-Step Guide: Cleaning Your Logitech Wireless Touch Keyboard K400 Plus

Step 1: Gather Your Cleaning Supplies

Before you start, make sure you have the right materials to safely clean your Logitech Wireless Touch Keyboard K400 Plus:

• Soft microfiber cloth 
• Isopropyl alcohol (preferably 70% or higher) 
• Compressed air canister 
• Cotton swabs 
• Small brush or a clean, unused paintbrush 
• Gentle electronics-safe cleaner (optional) 

Step 2: Power Off the Keyboard

First, turn off your Logitech Wireless Touch Keyboard K400 Plus and remove the batteries. This prevents accidental inputs and protects the internal circuits from moisture.

Step 3: Remove Surface Debris

Hold your Logitech Wireless Touch Keyboard K400 Plus upside down and gently shake it to dislodge any loose debris like dust, crumbs, or hair trapped between the keys.

Next, use a compressed air canister to blow out remaining particles between the keys and around the touchpad. Hold the can upright and spray short bursts to avoid moisture buildup.

Step 4: Wipe Down with a Microfiber Cloth

Dampen your microfiber cloth lightly with a 70% isopropyl alcohol solution (never apply liquid directly to the keyboard!). Gently wipe down:

• The keys 
• Touchpad surface 
• Palm rest area 
• Top and bottom casing 

This not only cleans dirt and grime but also disinfects your Logitech Wireless Touch Keyboard K400 Plus.

Step 5: Deep Clean Between Keys

For stubborn dirt around the keys:

• Dip a cotton swab in a small amount of isopropyl alcohol. 
• Carefully clean around each key without letting excess liquid drip inside. 

You can also use a small brush to sweep away particles caught in tight spots.

Step 6: Cleaning the Touchpad

The touchpad is the heart of the Logitech Wireless Touch Keyboard K400 Plus, so clean it gently:

• Use a separate microfiber cloth dampened with alcohol. 
• Wipe in circular motions to remove fingerprints, oils, and smudges. 
• Avoid pressing too hard to preserve the touch-sensitive surface.
