Using the cleaning tablets is easy – you only need the reusable SINI bottle and a tablet that fits in your pocket.
1) Fill the bottle with warm water.
2) Add a tablet and let it dissolve for 30 minutes.
3) Attach the nozzle and start cleaning!
The water should be hot, around 55°C. When using hot water, the tablet dissolves faster. It takes approximately 30 minutes for the tablet to fully dissolve in water. When using cold water, the tablet dissolves more slowly, in approximately 60 minutes.
The ready solution is usable for approximately a 6 months when it is stored at room temperature. The water quality and its cleanness level also affect the preservability. If you notice any changes in the solution’s colour, scent or consistency, we recommend you empty the bottle, rinse it thoroughly and prepare another bottle of cleaning spray. The products contain safe, food grade preservatives. Please note that if the cleaner is not used for a longer period of time, little build-up may appear at the bottom of the bottle. This is normal. Shake the bottle before use if build-up has formed.
The tablets keep in their packaging for 2 years as long as the packaging stays air and moisture tight.
Citric acid occurs in different fruits and the human body, for instance. The citric acid we use has been industrially manufactured as a raw material for the food industry, where it can be used as an acidity regulator or a preservative. Citric acid removes limescale efficiently and helps the cleaning tablet dissolve faster. Citric acid is a biodegradable and environmentally safe raw material.
Sodium bicarbonate is a salt that occurs in nature. It is often used in baking, where it acts as a leavening agent. In the SINI cleaners, sodium bicarbonate helps remove grease and burnt dirt.
Potash is a salt similar to sodium bicarbonate that also occurs in nature. The potash from birch ash has formerly been used to make lutefisk. Potash is commonly used in cleaners. It reduces surface tension and thus helps clean surfaces, which is why it is also used in SINI cleaners.
Sodium benzoate, also known as benzoic acid, is a preservative commonly used in the food and cosmetics industry. Benzoic acid naturally occurs in berries, especially lingonberries, cranberries and cloudberries. The acid and its salts are efficient against yeast, mould and certain bacteria in acid food products. In SINI cleaners, sodium benzoate is used as a preservative.
All colours used in our cleaners can be used as raw materials in the food industry and are thus very safe, food grade and biodegradable.
Aromatic, natural scents can often cause allergies, which is why we have used synthetic scents that cause less allergies and are suitable for most users. The scents we use have been certified to be extremely safe and to not contain any known allergens.
Surfactants, such as soap, are an effective agent commonly used in cleaners. Anionic surfactants help remove small particles efficiently and foam strongly.
Biodegradable cleaners break down into smaller compounds, such as water, carbon dioxide and different mineral salts and are therefore environmentally friendly. The Nordic Swan Ecolabel guarantees that the SINI cleaners are biodegradable. The criteria for the Nordic Swan Ecolabel include biodegradability and avoiding the use of harmful chemicals
No, the SINI cleaners are not tested on animals. The products have been tested at our in-house test laboratory in Kokemäki, Finland on different surface materials. Our products are also tested at the SGS international test laboratory, but never on animals.
The SINI cleaners have been awarded the Nordic Swan Ecolabel, which means that their environmental impact has been evaluated and that the products remove tough stains efficiently. Products cannot be awarded the Nordic Swan Ecolabel if they are not as efficient as a similar product that has not received the certificate. It proves that the product is both environmentally friendly and efficient. The criteria take the product’s life cycle and its environmental impact, such as global warming, eutrophication and chemicalisation of the environment, into account.
No. The SINI cleaners have been manufactured from the best possible raw materials without any harmful substances. Sometimes it might be difficult to know which substances are harmful. We have a practical mnemonic: always avoid biocides. According to specialists, cleaners with biocides should not be used. Biocides are antibacterial and too powerful for cleaning at home. They often cause allergies and are harmful to both the environment and the users. Biocides can also indirectly affect the evolution of antibiotic resistant bacteria. Biocides are not needed for cleaning, because the cleanness level achieved by regular cleners is more than enough. Avoiding biocides is also beneficial for human health since biocide-containing cleaners remove the normal flora from our environment. Less is more when it comes to cleaning!
The SINI cleaners’ pH-values have been designed to remove dirt as efficiently as possible from different surfaces. The bathroom cleaner has a pH of 4, as an acid solution removes limescale and rust efficiently. The kitchen and universal cleaner as well as the dish spray have a pH of 6–8. An alkaline solution removes grease efficiently.
The SINI cleaners have been designed to be as suitable and safe for as many consumers as possible. The products do not contain any known allergens. However, allergic reactions are very individual, which is why we recommend that people with allergies and sensitivities test the products before using them on a larger scale.
When using a sprayable cleaner, some residue might occur on the surfaces, but the amount is very small. The cleaned surface can be wiped down with a damp cloth if desired. When the cleaner has been wiped off the surface, the surface is safe to use. All the raw materials we use are food grade and harmless.
We have tested the cleaners on different surface materials. In our tests, the solutions have not stained any surfaces. The most sensitive material the products have been tested on is a sauna bench made of light, untreated lumber. We recommend being careful when testing the products on sensitive and porous surfaces, such as natural stone. The cleaners are not made for cleaning textiles.
