Twin Power
Outdoor Express

The Twin Power Outdoor Express made a very good impression in our test. The environmentally neutral cleaning agent consists of two transparent, odourless components. It is supplied in child-safe bottles, which are connected by a common spray head and enable precise dosing on the surface to be treated. The effect was convincing in the practical test. The cleaner was able to break down and dissolve soiling (organic compounds) quickly and effectively . Overall, Twin Power Outdoor Express impresses with its effectiveness, user-friendliness and sustainability.

  • Quick and thorough cleaning
  • Reusable spray head
  • Generous filling quantity
  • Sustainable formulation
  • Potentially corrosive to metal

Packaging and contents

Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

The Twin Power Outdoor Express is supplied in an attractively designed box that makes a positive impression as soon as it is opened.

The cleaning agents with the spray gun are securely placed inside the packaging, with additional protection of the spray nozzle provided by a special film. The use of this film is both sensible and necessary due to the material to ensure the integrity of the product during transport and storage. Overall, the packaging exudes a high-quality and well thought-out design that leaves a lasting positive impression.

Twin Power Outdoor Express makes a very good visual impression. The special cleaner is supplied in two 400 ml bottles with a childproof cap. The spray head supplied enables precise dosing on the surface to be treated. The workmanship is of high quality and flawless, so there are no faults to report. The cleaning gun is also surprisingly solid and therefore makes a very high-quality impression. Both components are transparent and odourless. The product is also environmentally neutral and contains no microplastics, chlorine, silicones, solvents, preservatives or synthetic colourants. The product is labelled with warning notices . The cleaning agent must be kept out of the reach of children .

The Twin Power Outdoor Express product test was carried out using a basic cleaning of the patio. Firstly, the product was sprayed generously onto the concrete slabs and worked in with the outdoor brush provided. After a reaction time of around 10 minutes, the surface was rinsed with water and scrubbed again with the brush. This cleaning process effectively removed almost all dirt. In the case of more stubborn weathering, the cleaning process was repeated until all residues were completely removed. The product is primarily used outdoors on patios, balconies and awnings and removes traces of weathering and plant residues. Before using Twin Power Outdoor Express, it is recommended to test the compatibility of the cleaning components on an inconspicuous area to avoid possible damage. It should also be noted that the product can have a corrosive effect on metal.
A particular highlight of the Twin Power Outdoor Express is the reusable spray head and the generous filling quantity of 2 × 400 ml, which guarantees a long service life. Both cleaning components can be reordered online. The high yield ensures effective cleaning while at the same time conserving resources.

At the time of testing, the product was not yet officially listed on Amazon. Therefore, there are no further reviews, so this point is neglected in the evaluation.

Prices of up to €46 are charged on the Internet for equivalent products. Very cheap products are available from as little as €6 . The Outdoor Express from Twin Power is therefore currently in the middle price segment with a price of €17.99. For the quality and performance received, the price-performance ratio is good.
