What size are the 7WASH cleaning products?

The 7WASH care products (Wash Shampoo, Wash & Wax, Hydro Slick, 3D-Protector, Glass Cleaner, Interior Cleaner, Air Freshener and Tire Dressing) each come in a 500 ml bottle.

How do I use 7WASH Wash Shampoo?

Shake well, add 30–90 ml of shampoo to a wash bucket with water or to the reservoir of a foam cannon, rinse the vehicle first, wash with a wash mitt or apply the foam evenly, rinse thoroughly with clean water and dry with a microfiber cloth. The shampoo is pH-neutral and suitable for paint, plastic, glass and coated surfaces.

When should I use the waterless Wash & Wax?

7WASH Wash & Wax is designed for lightly soiled vehicles only: it removes light dirt, dust and fingerprints and leaves a protective gloss without rinsing. Remove heavy dirt, sand or mud first, then spray section by section, wipe with a clean microfiber cloth and buff with the dry side. Suitable for paint, glass, plastic and smooth surfaces.

How do I apply the ceramic quick sealant (Hydro Slick)?

Clean the vehicle thoroughly and make sure the surface is dry and cool. Spray Hydro Slick lightly onto a microfiber cloth or directly onto the surface, spread evenly section by section, let it flash briefly and buff off with a clean microfiber cloth. For best results keep the vehicle dry for 1–2 hours after application. Suitable for paint, plastic and smooth surfaces.

Which surfaces is 3D-Protector for?

3D-Protector cares for plastic, rubber and vinyl inside and outside the vehicle, e.g. bumpers, trim, door panels, rubber seals and engine bays, with UV protection and a natural, non-greasy finish. Do not apply it to floors, pedals, bicycle tires, steering wheels, other surfaces that could become slippery, or glass.

How do I apply 7WASH Tire Dressing?

Clean and dry the tire thoroughly, put a small amount on an applicator sponge or pad, spread it evenly over the tire sidewall and let it absorb briefly; apply a second layer for extra gloss. The non-drip gel gives a deep black finish with UV protection. Never apply it to the tread, brakes, pedals or floors.

Is 7WASH Glass Cleaner safe on tinted windows?

Yes. According to the product description, 7WASH Glass Cleaner is safe for tinted windows. It removes fingerprints, grease, insect residue and road grime streak-free from interior and exterior glass, mirrors and displays.

Which interior surfaces can I clean with 7WASH Interior Cleaner?

7WASH Interior Cleaner is suitable for plastic, fabric, leather and vinyl, e.g. dashboards, door panels, center consoles, seats and carpets. Spray onto a microfiber cloth or the surface, wipe evenly, let it dwell briefly on heavier dirt and wipe dry. It leaves no residue and no artificial shine.

Can 7WASH Air Freshener be used through the air conditioning?

Yes. Set the air conditioning to cold and recirculation mode and spray 1–2 bursts into the passenger footwell. Otherwise spray lightly onto carpets, upholstery or into the interior air; do not oversaturate and do not spray onto face or body.

What are the specifications of the 7WASH cordless foam sprayer?

The 7WASH cordless foam sprayer is electric, runs on a rechargeable 12V lithium battery and delivers a constant pressure of 3.6 bar, so no manual pumping is needed. It is used for pre-washing with snow foam, car shampoo or pre-cleaners on cars, motorcycles, wheels and bicycles.

What sizes are the 7WASH microfiber towels and how do I wash them?

The premium microfiber cloth measures 40 × 40 cm (single or 2-pack) and the car drying towel 60 × 90 cm. Both are reusable: rinse after use or machine wash without fabric softener.
