Upholstery maintenance

Regular cleaning is important in order to keep the upholstery looking its best and to prolong its life. Dust and dirt wear the textile and also reduce its fire-retardant properties.

Normal cleaning
Vacuum frequently on medium power, ideally every week. Remove non-greasy stains by carefully dabbing with a lint-free cloth or sponge wrung out in clean warm water. Afterwards, if necessary, clean by dabbing with soapy water or water with a little washing-up liquid added - See formulae. Finally, dab the surface with clean, tepid water.

Do not rub the material hard because this could result in loss of colour or perhaps damage any nap. Stains from dark jeans may occur. This is caused by excess dye. Unfortunately, stains cannot be removed by washing or dry-cleaning. This is not an error in the upholstery.

Soapy solution is made of 1/4 dl soap flakes to 1 litre of hot water; leave to cool before use. Washing-up liquid solution. Max. 1 teaspoonful of washing-up liquid to 1 litre of water. With concentrated agents, use a few drops per litre of water.

Care of powder coated steal

Powder-coated steel should be cleaned only with a damp cloth and then well dry rubbed.

Maintenance of our leather

For the Christian Dorn collection we use leather of the company Leder-Fiedler

Leather: Classic Nappa
Classic Nappa is pigmented leather. Pigmented leathers are easy to care. They have a protective coating on the surface. Dust off the leather from time to time with a soft, dry cloth. In case of dirt or stains clean the leather wit Mild Leather Cleaner. Fresh stains can be removed immediately with a soft cloth or paper towel. Don’t rub to hard! Clean remaining dirt and stains with Mild Leather Cleaner. Protect the leather with Leather Protector to keep the leather soft and smooth. Leather Protector contains moisturizing oils and UV-Filters to prevent fading. Depending on the use, heating and sun intensity, the leather should be treated all three to twelve months.

Leather: DAKOTA
Dakota is a pure aniline and natural cow leather. It is manufactured with high-quality colour- and fatting agents. Through the open pores the leather is pleasantly warm, but also more sensitive to stains.

For everyday cleaning, it is enough to dust the leather occasionally with a feather duster or dry cloth. In addition, stains can be cleaned with a slightly damp cotton. Not too wet to avoid edges. Dry the moistened area with a hair dryer with cold air, so that no water stain may arise. Always exercise a cleaning test in the hidden area.

Leather: Tribe
The TRIBE is a semi nubuck. Nubuck leathers are leathers polished on the surface. As a result these leathers are warm and open-pored. It is enough to clean nubuck leather occasionally brushing off the leather. Areas which have become greasy can be roughened again using an abrasive disc and afterwards be cared with an Aniline protector. Fresh stains first absorb with a terry cloth by pressing it between your fingers. Do not rub! That can change the gauze.

In addition, residual stains can be cleaned with a slightly damp cotton. Not too wet to avoid edges and not too much rubbing. Dry the moistened area with a hair dryer with cold air, so that no water stain may arise. Always exercise a cleaning test in the hidden area. Afterwards brighten remaining dark spots with an abrasive disc and then care with an Aniline Protector.

Important rules for leather products

First check if the leather is absorbent. On absorbent leathers a rubbed in drop of water will sink into the surface and darken the leather. On non-absorbing leathers water beads off. Absorbent leathers are much more sensitive.

First test all products and treatments in a hidden area. Especially when working on absorbent leather. Absorbent leather can easily be damaged when treated wrong.

Regular cleaning and caring of furniture leather prevents staining and extends the life time.

Always clean dirty leather before using leather care products.

Light leathers are sensitive to “Jeans-coloration”. Always clean immediately after visible stains to avoid coloration sinking into the surface.

Always work with the recommended products from seam to seam.

Don’t rub to hard on stains which can not be removed. You risk damaging the surface. Contact a specialist first.

Don’t use aggressive solvents (acetone, nail polish remover, turpentine etc.) to remove stains and dirt. You will cause damages.

Don’t use wrong care products like shoe polishes and cosmetic creams.

Leather is sensitive to direct sunlight. Leather can fade and dry out. Try to avoid direct sunlight. Always use care products with UV-protection.

Leather gets traces of use after a while. Leather can fade over the years. If changes occur (scratches, stains, fading e.g.) react early enough. The earlier leather is helped, the less damage occurs.

Leather has an optimum humidity of 40 to 60% and needs ventilation. Leather can become moldy when humidity is above 70% and/or without enough air circulation.
