Leather perforation - Perforated leather
A perforation of leather is the cutting of holes into the surface at regular intervals. Through the perforation, little leather pieces are punched out and removed.
Car leather is provided with a covering and protective colour layer so that it meets the desired characteristics of automotive manufacturers (stain resistance, abrasion resistance, UV resistance, etc.). Non-pigmented smooth leather (aniline leather) is too delicate for car interiors.
The disadvantage of surface colourations is the reduced breathability of the leather. Therefore, car seats are often perforated in the contact areas. Due to the perforation, the air permeability of the leather is noticeably increased and sweating in the contact area is significantly reduced.
Car manufacturers such as Mercedes, Opel, Ford, Porsche and also VW (New Beetle) use perforated leather.
Perforations are usually round, but can also be angular.

Occasionally in car leather: perforation for decorative reasons or brand advertising.
Perforated imitation leather.
Perforated hand bags.
For production reasons, it is also possible to laminate and then perforate. The perforation holes then also pass through the cushion material on the back.
Furniture cushions get a perforation on the back to allow venting of the cushions. At the same time, it is used for advertising with own brand.
Perforation of leather in the leather workshop
There are smaller machines with which leather can be perforated in the leather workshop. Different punching tools can be used to achieve different patterns and hole sizes.
The leather is perforated quickly.
The perforation tools punch round holes.
The cut-out leather pieces land in the collecting container of the perforating machine.
Embossing with intentional perforations of the leather
Some leathers are so heavily embossed, that holes are created in the leather. In contrast to perforation, no leather is punched out and removed.

Cleaning and maintenance of perforations
Perforation in leather is sensitive to moisture. Therefore, the following procedure must be followed during cleaning and care: in the area of the perforation, apply all products only sparingly in order not to fill the holes or to soak them too much. The moisture can penetrate causing the edges to swell or the moisture can soak the cushioning foam behind and wet the leather with remaining stains.
When cleaning, the following procedure is recommended: dispense some leather cleaner foam onto a cloth or a brush and then clean the leather carefully. Remove the foam and cleaning residue with a cloth slightly moistened with water. Also, when applying care products, slightly moisten a cloth with the care product and wipe the leather gently.
If you follow these rules, there is no risk due to the perforation, and the leather will remain beautiful for a long time.
Typical stains caused by too wet cleaning and/or care application.
Perforated leather can also react sensitively to penetrating or dripping water. Stains may remain after drying. Unfortunately, there is no surefire way to remove it. You can try cleaning the entire surface, but not too wet, and with luck it will cause a uniform change in the surface, which is then no longer noticeable, which then has to be carried out on all perforated leather. If the procedure does not work, it is better to consult a leather specialist. Further cleaning with more water or more aggressive agents can actually worsen the condition.

If perforated leather is torn or otherwise damaged, it must usually be replaced by a trimmer. The perforation tears with the same effect as the perforation of a stamp. The leather then tears along the row of holes. Specialised leather repair companies can sometimes repair such damages without replacing the leather. However, a visible scar mostly remains and only skilled and experienced craftsmen can do such work well.
Tears in the perforated leather cannot be repaired invisibly. A scar remains.
