Odour removal in seven steps<\/h2>\n\n\n\n
The order is important. If the source isn\u2019t removed first, the smell will often return, no matter how strong the cleaning products you use.<\/p>\n\n\n\n
1. Remove the source and any coarse debris<\/h3>\n\n\n\n
Start by removing the source of the odour. This could be food residues, liquids, organic matter, damaged materials or porous surfaces that cannot be cleaned properly.<\/p>\n\n\n\n
Anything that continues to emit odours or cause contamination must either be removed or assessed for further decontamination. The aim is to eliminate the cause before odour treatment begins.<\/p>\n\n\n\n
2. Treat odours with Biofresh<\/h3>\n\n\n\n
Once the source has been removed, you can begin odour treatment with Biofresh. If necessary, heat the room to approx. 25 \u00b0C before treatment \u2013 heat activates the odour and ensures the product works more effectively on the materials.<\/p>\n\n\n\n
Use Biofresh undiluted or diluted up to a ratio of 1:10. On particularly affected areas, you can use a more concentrated solution. Leave the product to work for 5 to 30 minutes. For strong or deep-seated odours, a longer application time may be required.<\/p>\n\n\n\n
3. Wash thoroughly with ProffOx Lemon<\/h3>\n\n\n\n
After the initial odour treatment, wash water-resistant surfaces thoroughly with ProffOx Lemon. Use the product undiluted or diluted up to a ratio of 1:50, depending on the surface and the level of soiling.<\/p>\n\n\n\n
Clean the surfaces mechanically wherever possible. It is important to actually remove organic contamination, not just wet the surface with chemicals. Rinse thoroughly where necessary, particularly before applying Biofresh \u2013 Biofresh is not compatible with acidic agents.<\/p>\n\n\n\n
4. Disinfect as required<\/h3>\n\n\n\n
Once the surfaces have been cleaned, they can be disinfected if necessary. Use ProffOx DES, either undiluted or diluted 1:2, on water-resistant surfaces. On surfaces susceptible to bleaching, textiles or more delicate materials, Proff Elyte should be used instead.<\/p>\n\n\n\n
Always test on a small area first, and choose a product suitable for the surface. Disinfection should not replace cleaning \u2013 it should be carried out after organic matter has been removed.<\/p>\n\n\n\n
5. Treat the area again if the smell persists<\/h3>\n\n\n\n
If the odour is still noticeable after washing, drying and airing, Biofresh can be reapplied.<\/p>\n\n\n\n
Before repeating the treatment, you should consider whether there is a hidden source of odour or contamination. The odour may be trapped in porous materials, under floors, behind skirting boards, in cavities or in materials that should have been removed. Do not treat the same surface repeatedly without checking that the source has actually been eliminated.<\/p>\n\n\n\n
6. Dry fog for extreme odours<\/h3>\n\n\n\n
In cases of extreme odours that persist after removal, cleaning, disinfection and after-treatment, dry fogging may be used as a final method. Use ProffOx Max as a ready-to-use solution with the PN1500 thermal fogger.<\/p>\n\n\n\n
Use a dose of 1 litre per 100 m\u00b3 \u2013 measure the volume of the room before you start, rather than guessing. Before treatment, ensure that ventilation is switched off and all ignition sources are removed, and that the room is clear of people and animals. After treatment, ventilate the area thoroughly for 2 to 24 hours.<\/p>\n\n\n\n
7. Check and document<\/h3>\n\n\n\n
Only assess the results once the area is completely dry and well ventilated. Document which surfaces have been treated, which products have been used, the mixing ratios, dosage, exposure time, what has been removed or discarded, and whether further decontamination is required.<\/p>\n\n\n\n
If the odour persists, you should check whether the source has been removed, whether porous materials are still emitting odours, or whether the treatment has not reached the area where the odour is coming from.<\/p>\n\n\n\n

Key rules of chemistry<\/h2>\n\n\n\n\n- Do not mix chemicals<\/li>\n
- Rinse thoroughly before using Biofresh if acidic products have been used<\/li>\n
- Biofresh must be allowed sufficient time to take effect<\/li>\n
- ProffOx DES is used on water-resistant surfaces \u2013 Proff Elyte should be used where ProffOx DES may cause discolouration or be too harsh<\/li>\n
- Dry fogging is only used once the source has been removed and the surfaces have been cleaned<\/li>\n<\/ul>\n\n\n\n
<\/div>\n\n\n\n
Why temperature and exposure time determine the result<\/h2>\n\n\n\n
Two factors have a significant impact on the result: temperature and exposure time.<\/p>\n\n\n\n
The room should be heated to around 25 \u00b0C before odour treatment. This activates the odour and allows the chemicals to work more effectively on the materials. On cold surfaces, the process is slower, and the product often penetrates less effectively into the areas where the odour is present.<\/p>\n\n\n\n
The application time is just as important. Biofresh should not simply be applied and wiped off straight away. The product should be left to work for 5 to 30 minutes, and in the case of strong odours, it may take longer. If the odour persists after applying the product at the correct temperature and for a sufficient duration, this is often due to a hidden source. In that case, you should look for it before proceeding to dry fogging.<\/p>\n\n\n\n
<\/div>\n\n\n\n
The products in the method<\/h2>\n\n\n\n
The method uses products that serve different purposes: Biofresh provides an immediate solution to odours and acts as a finishing treatment if the odour persists. ProffOx Lemon is used for thorough cleaning of water-resistant surfaces, ProffOx DES disinfects cleaned surfaces, and Proff Elyte is used on surfaces susceptible to bleaching, textiles and other sensitive materials. A low-pressure sprayer and wet fogger are used for controlled application, whilst ProffOx Max with the PN1500 thermal fogger is used for extreme odours that require a final dry fogging treatment.<\/p>\n\n\n\n
