How to do 

Once your supplies are ready, you should follow the following process in sharpening your electric razor:

Step 1: Cleaning your device

Over time, residue from dead skin and oils can coat the razor, making it less effective. This is why before sharpening your electric razor; you will need to ensure that all parts including the battery compartment, switch cover, handle, head, guard, cartridge, and any attachments are clean.

You should also remove any debris from the housing before starting the process. This step ensures that there won’t be any dirt particles stuck between the components when they get rubbed together during the sharpening procedure.

Step 2: Disassemble the electric razor

After cleaning everything thoroughly, disassemble the electric razor by removing screws one at a time until you reach the bottom part where the batteries are located. Remove the two small metal plates covering the batteries. You should then take out the four plastic clips holding the main body together. 

After removing these pieces, rinse under running hot water so that no residues are left. Now, carefully separate each component from the others using tweezers. 

Use a small brush to clear the hairs. Check out for the tiny strands of hair that get stuck in the blades and remove them.

Step 3: Applying toothpaste

After removing the hair residues, you should apply toothpaste on the blade area and the razor screens. Use a soft brush to apply a thin layer of paste on all pieces of the electric razor. Do this slowly but surely ensuring that you don’t miss any spot. Allow the paste to dry completely before proceeding further. Avoid applying too much toothpaste as this will bog down the razor. 

Once done, rinse the brushes again under running hot water. Turn on the razor and push it slowly against the toothpaste. This will ensure that the toothpaste gets in all holes. In case the razor’s head heats up, unplug it. Keep repeating this process.

After applying the paste evenly over the whole area, place the electric razor back into position and press down firmly while turning the knob clockwise. Continue doing this until the blade is grounded to the desired length.

If necessary, repeat the grinding process several times until the blade reaches the right size.

Step 4: Washing the Blades

To ensure that your new blades work well, wash them with hot water after sharpening. Rinse them under running hot water and allow them to air dry.

Step 5: Reassembling the Parts

When finished, reattach the four plastic clips first followed by the two metal plates finally, replace the screw covers and tighten them securely.

Step 6: Testing the Newly Sharpened Blades. 

Test the newly sharpened blade by placing the electric razor against your face.

Ensure that it cuts smoothly without causing discomfort. If needed, adjust the angle slightly until you find what works best for you.

Step 7: Storing the Electric Razor. 

Store your electric razor away from direct sunlight since exposure to heat causes deterioration of the lubricants present in the system. Also, keep it away from moisture since condensation could form within the housing.

Lastly, store it somewhere cool and dark.

It’s advisable to ensure that you are using regular toothpaste instead of extreme whitening. This is necessary as toothpaste contains large and gritty particles. This isn’t also effective in cleaning and sharpening.
