Why do you need to clean tent fabric before impregnating it?
Tent fabric should always be cleaned thoroughly before impregnation, as dirt, dust and other contaminants prevent the impregnating agent from adhering well to the fibres. A dirty surface causes the water-repellent coating to be applied unevenly and to be less effective.
Impregnating tent fabric without prior cleaning creates a barrier between the fabric fibres and the protective agent. Green deposits, mould and other dirt prevent the impregnating agent from penetrating deeply enough. The result is a tent that leaks after the first rain because the protective coating does not adhere sufficiently.
Moreover, impregnating dirty tent fabric can cause stains to become permanently fixed. The impregnation locks the dirt in, so to speak, making it much more difficult to remove later. A clean base is therefore essential for optimal water-repellent properties and a longer life of your tent.
What products do you need to prepare tent fabric for impregnation?
To prepare tent fabric for impregnation, you need a suitable detergent specially designed for outdoor textiles, a soft brush, clean water and enough time to allow the fabric to dry completely. The choice of cleaning agent depends on the degree of soiling.
For light soiling, such as dust, leaves and superficial green deposits, a mild tent shampoo is sufficient. These products are specially formulated to clean tent fabric without damaging the fibres. For stubborn stains, mould or ingrained dirt, you need a more powerful cleaner that can penetrate deeper into the material.
Avoid household cleaners such as bleach, detergent or all-purpose cleaners. These can damage your tent's water-repellent coating or attack the fibres. Pressure washers are also not recommended, as the powerful water jet can damage the coating and force water through the seams.

How to clean tent fabric step by step before impregnation?
Start by setting up the tent on a flat surface and rinse the cloth with lukewarm water to remove loose dirt. Then apply the detergent to the damp cloth and let it soak in for a few minutes before gently brushing with circular motions.
Work systematically from top to bottom, paying extra attention to heavily soiled areas, such as the underside of the tent and areas around zips and seams. Use a soft brush to avoid damaging the fibres. For stubborn stains, you can leave the cleaner on longer, but always follow the instructions on the packaging.
Then rinse the tent fabric thoroughly with clean water until all foam and soap residue has disappeared. Residues of detergent can interfere with impregnation later on. Especially check the seams and folds, where soap residue can easily accumulate. Proper rinsing is crucial for the success of subsequent impregnation.
How long does tent fabric need to dry before impregnation?
Tent fabric must be completely dry before impregnation, which takes 24 to 48 hours in normal weather conditions. The canvas should no longer show any damp spots and should feel dry all over, including seams and thicker parts.
The drying time strongly depends on the weather, humidity and thickness of the tent material. Canvas tents need more drying time than thin nylon tents. Ensure good ventilation by fully opening the tent and opening all zips and flaps. In humid weather, drying can take up to three days.
Test if the fabric is completely dry by putting your hand on several spots, especially at seams and reinforced parts. If you still feel moisture or coolness, wait longer. Impregnating on damp fabric significantly reduces its effectiveness, as water prevents the impregnating agent from adhering properly to the fibres.

How often should I clean and re-impregnate my tent fabric?
This depends on how often you use the tent and under what conditions. For recreational use, annual cleaning and impregnation is usually sufficient. For intensive use or after exposure to a lot of rain, sun or dirt, you may need to repeat this process every 6 months. Test the water repellency by dripping some water on the canvas - if it no longer beads off, it is time for new impregnation.
Can I clean tent fabric in the washing machine before impregnating?
This is only possible with small tents that fit in the machine and if the manufacturer allows it. In that case, use a special tent washing detergent and wash at low temperature (30°C) without spinning. Large tents are better cleaned manually as the washing machine can damage the material and affect the coating.
What do I do if there are still stains on my tent fabric after cleaning?
Stubborn stains often require a second treatment with a more powerful cleaner such as Heavy Duty Cleaner. Leave the product on longer (up to 15 minutes) and brush gently. For very old stains, you can repeat the process, but accept that some stains may be permanent without affecting the functionality of the tent.
Is it bad if I accidentally apply impregnation agent on still damp tent fabric?
This significantly reduces the effectiveness of the impregnation because the water prevents the agent from adhering properly to the fibres. Stop impregnating, let the fabric dry completely and then reapply impregnating agent. It is better to wait patiently than to have to redo the process.
Can I use different brands of detergent and impregnating agent interchangeably?
Although technically possible, we recommend using products from the same brand that are coordinated with each other. Different chemical compositions can counteract each other or reduce effectiveness. The Rokimi system, for example, is specifically designed to work optimally together for best results.
How do I avoid damaging my tent during the cleaning process?
Always use soft brushes, not hard abrasives, and brush with circular motions without applying too much pressure. Avoid high-pressure sprays and only use products specially designed for tent cloth. Test new products first on a small, inconspicuous piece of cloth to make sure no discolouration occurs.
