Safety Information

- Use with caution to avoid cuts or nicks.
- Discontinue use if irritation occurs.
- Store in a dry place.
Setup: Blade Installation
The MERKUR 23C features a three-piece design for secure blade placement. Follow these steps to install a new double edge blade:
- Unscrew the handle from the head of the razor by turning it counter-clockwise. The head consists of two parts: a top cap and a base plate.
- Carefully separate the top cap and the base plate.
- Place a new double edge razor blade onto the alignment posts of the base plate. Ensure the blade is centered and flat.
- Place the top cap over the blade, aligning its posts with the holes in the blade and the base plate.
- Screw the handle back onto the assembled head by turning it clockwise until it is finger-tight. Do not overtighten, as this can damage the razor.

Operating: Shaving Instructions
For an optimal and comfortable shave with your MERKUR 23C safety razor, adhere to these guidelines:
- Preparation: Begin with a clean, wet face. Apply a quality shaving cream or soap to create a rich lather. This softens the hair and provides lubrication, reducing friction.
- Angle: Hold the razor at approximately a 30-degree angle to your skin. This is a common starting point, but you may adjust slightly to find the most effective angle for your face and blade.
- Pressure: Use minimal pressure. The weight of the razor itself is often sufficient. Allow the blade to glide across the skin. Excessive pressure can lead to nicks, cuts, and irritation.
- Stroke: Use short, controlled strokes in the direction of hair growth. Rinse the razor head frequently under running water to clear away lather and cut hairs, maintaining optimal cutting efficiency.
- Multiple Passes: For a closer shave, you may perform multiple passes. Subsequent passes can be across the grain or against the grain, depending on your skin sensitivity and desired closeness. Always reapply lather between passes.
- Rinsing: After shaving, rinse your face with cool water to help close pores. Apply an aftershave balm or lotion to soothe and moisturize the skin.

Maintenance
Proper maintenance ensures the longevity and consistent performance of your MERKUR 23C razor:
- After Each Shave: Rinse the razor thoroughly under running water to remove all soap and hair residue. Gently shake off excess water.
- Drying: Allow the razor to air dry completely before storing. Do not wipe the blade, as this can dull it or cause cuts.
- Deep Cleaning: Periodically disassemble the razor (as described in the Setup section) and clean all components with a soft brush and mild soap. Rinse thoroughly and dry completely before reassembly.
- Blade Replacement: Replace the blade every 4-7 shaves, or as soon as you notice any tugging, pulling, or discomfort. Used blades should be disposed of safely in a blade bank or suitable container.

The three-piece design facilitates easy disassembly for thorough cleaning and maintenance.
Troubleshooting
If you encounter issues with your MERKUR 23C razor, consider the following common solutions:
- Nicks or Cuts: This is frequently caused by an incorrect shaving angle, excessive pressure, or a dull blade. Ensure you are holding the razor at approximately a 30-degree angle, applying light pressure, and replace the blade if it feels dull or drags.
- Skin Irritation/Razor Burn: Verify proper skin preparation (warm water, sufficient lather). Always shave with the grain first. Reduce pressure. A fresh, sharp blade is crucial for minimizing irritation.
- Ineffective Shave: Check if the blade is correctly installed and securely tightened. Ensure the blade is sharp; replace if necessary. Adjust your shaving angle to find the most effective cutting position.
- Razor Feels Slippery: While the knurled handle is designed for grip, wet hands can still reduce friction. Ensure your hands are as dry as possible or use a towel for better grip during shaving.
