- microfiber cloth
- Tape for masking the edges
- Water hose and connection

Step 1: Pre-inspection and cleaning
Road debris, mosquitoes, rain debris and many other particles stick to the headlamps and can interfere with visibility. In order to assess the extent to which damage to the headlamps is present, you must therefore first perform a cleaning. This is also important in terms of polishing because dirt must not be rubbed over the headlights.
- Use a soft sponge, car shampoo and warm water. Make sure that you never wipe dry over the potholders, but always work with enough liquid. This will prevent damage.
- Then let the headlights dry well.
- Check the headlights for scratches and damage. Milky discoloration and small scratches can be removed by polishing in most cases. However, if it is cracked covers or heavily scratched headlights, then an exchange is necessary.
Step 2: Glue the edges
To prevent damage to the paint, you must first tap the edges. Otherwise, when polishing, you may accidentally touch and damage the paint.
Step 3: The grinding
Use very fine sandpaper. You should choose a grain size between 1, 500 and 3, 000. Moisten the paper and then gently pull it over the headlight cover.
Tip: Work without much pressure and gently rub across the surface. Within the span of 1, 500 and 3, 000, you can start with a coarser sandpaper and then choose a finer version.
Step 4: Clean the surface
Rinse residues from grinding with water. Use enough water so that the grains will not scratch.
Tip: A garden hose is very well suited to rinse off the residues fast, uncomplicated and effective.
Step 5: The polishing
Now you have to polish the headlights. Use a special polish, for example an aluminum polish. But toothpaste can also be used.
- Apply the polish with a microfiber cloth.
- Polish in circular motions.
- First concentrate on a smaller area and work your way slowly.
- Give yourself plenty of time as polishing requires patience.
Step 6: Seal headlamps
In the car accessory trade plastic bonding agents are offered. These are suitable for protecting the headlights.
Step 7: Final check
In the dark place the vehicle in front of a smooth and white house wall. Turn on the headlights and check the lighting effect. The luminosity should be high and the transparency must be given.
Polish by hand or use a polishing machine ">
When polishing, you have the choice between manual work and the use of a polishing machine. The advantage of the technical support lies in the particularly uniform result. The polish is easy to apply and the result improves. The disadvantage is the increased effort.

Headlight made of glass
Especially with older vehicles, the covers are often made of glass. Polishing is also possible in this case, but more complex and associated with a higher risk in terms of damage.
Method 1: For light scratches in the glass, do the following:
- Thoroughly clean the headlights with warm water, a soft car sponge and car shampoo.
- Let the headlights dry well afterwards.
- Apply toothpaste with a soft cloth. Then rub in uniform circular motion over the glass.
- Then wipe off excess toothpaste from the glass and check the result.
Method 2: Try out an ammonia solution
- Mix 0.75 liters of water with approximately 15 milliliters of ammonia.
- Moisten a cleaning cloth with the solution.
- Rub in circular strokes over the glass, more precisely over every single scratch.
- Wipe the surface clean and check the result.
Method 3: The procedure for larger scratches
- Choose a product that is suitable for removing scratches in glass.
Tip: Corresponding funds are offered in hardware stores and often also in furniture stores. Ask for a special kit and describe the glass and scratches precisely as different products are available.
- Follow the instructions in the instructions. Often the kit includes a grinding wheel, which you can attach to the drill. In this case, set the drill to the lowest level. Grind until an improvement is visible or it can be seen that the procedure is not effective.
Method 4: Baking soda
- Mix water with baking soda. There must be a soft paste. The consistency should be similar to a pudding and liquid as well as loose. Stir the paste with a spoon and make sure that the formation of lumps is prevented.
Tip: The mixture must not be too dry, otherwise scratches may occur during use.
- Apply the paste and rub gently and circularly over the glass.
- Then clean the cover with a soft, clean cloth and water.
Important tips and hints
Typical mistakes when polishing the car headlights
1. If the headlamps are treated with a conventional car polish, then the material will be damaged. Therefore, you must use special products.
2. The headlights are not cleaned before polishing. In this case, you would rub the dirt particles over the glass during polishing and thus produce small or larger scratches. Even the finest dust particles lead to damage that may not be visible at first glance. Due to the incoming light, however, there is a scattering and thus a poor lighting effect, which can be a danger.
