Hermann Sachse
Hard oil

In our test, the hard oil from the Hermann Sachse brand left a very good impression. As well as offering a very high level of protection for the wood, the product is also extremely easy to use. What’s more, the oil is vegan and has been produced as naturally as possible in Germany. Nevertheless, a more pleasant odour during application would have been desirable. After drying, the odour is no longer noticeable.

Advantages

✅ Extremely high protection for the wood
✅ Vegan
✅ Simple application

Disadvantages

❌ Unpleasant odour during application


The first impression

The packaging and labelling

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. Of course, adequate protection of the product must also be ensured.

The hard oil from Hermann und Sachse arrived in the typical Amazon box . The box was undamaged and could be easily opened with a knife. The box contained the tin of hard oil wrapped in plastic film. The plastic bag might not have been necessary, but it also contained the product instructions. In this case, the product was completely protected and the can of hard oil was therefore in perfect condition. The packaging of the hard oil is partially recyclable. Unfortunately, the plastic bag is not recyclable, but the Amazon box is.
Overall, the Hermann und Sachse hard oil makes a very good impression. The hard oil tin was not damaged and the parcel was in very good condition.

After unpacking

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the pack complete and does the manufacturer make it as easy as possible for me to use the product straight away?

Theplastic bag contained a beautifully designed tin of hard oil. Visually, the tin has a nice look. Instructions for use and further information can be found on an extra label. As the instructions are enclosed in 8 languages, they are a little confusing. Contact information is provided. As this product is a utility product, the delivery is absolutely sufficient and efficient.

The first time in your hand

Product processing and appearance

ℹ️ Before we start the practical test, we take a close look at the product processing. How high quality are the materials used? Is the look and feel satisfactory?

*The maximum score is 100 points

The hard oil comes in a beautifully designed aluminium can. In the hand, this has a stable effect and shows the high-quality production. The oil itself is 100% solvent-free and is also labelled as suitable for children’s toys. The oil is also vegan. This makes the product very sustainable. Unfortunately, the cap on the tin is not very suitable for dispensing the oil. However, it is fitted with a child safety lock so that children cannot get hold of the oil.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

*The maximum score is 100 points

The Hermann Sachse brand hard oil is very easy to use as it is explained in detail in the instructions. Once the oil has been applied, the wood is very well protected and water-repellent. The oil is also excellent for indoor use. The oil is 100% solvent-free and is only made from natural raw materials. However, the appearance of the wood after application is not quite as described. As you can see from the picture on the right, the oil is not completely transparent, but slightly darker than before. However, it was also described in the instructions that the colour shade differs depending on the type of wood.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we look at how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also analyse consumer reviews and check whether the critical and positive reviews are actually justified.

*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.6 stars. The fact that it is not transparent as described is often criticised. Many customers like the fact that the oil provides excellent protection. In our practical test, we were able to confirm that the wood protection was very good and that the colour of the oil was not so good.

Prices of up to €15 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €8. With a price of €11.99, Hermann Sachse’s hard oil is currently in the middle price segment. The price ratio is very good for the quality and scope of services you get.
