Cotton tents can be cleaned easily. However, bear the following in mind. Often, older cotton tents are still watertight thanks to the original impregnating agent, dirt on the tent cloth and all the cotton fibres shed by the yarn, for example. After all, cotton wears.
This is removed by cleaning and often leaves you with a tent canvas that needs to be impregnated once or numerous times. It is preferable to do this while the canvas is under tension.
- First, clean the canvas with lukewarm water and a strong, soft brush.
- Then spray Ultramar Sprayhood & Tent Shampoo on the tent while it is still wet and thoroughly brush the dirt loose.
- Leave the product to soak in for about 20 minutes, then remove the shampoo and dirt with plenty of water and a brush. Rinse well.
- Now, allow the canvas to dry.
- For heavy soiling, treat additionally with Ultramar Power Cleaner.
- Spray Power Cleaner onto the tent and leave to soak in for about 1 hour. Spray a little extra every hour if necessary. Only do this until all soiling has disappeared. (First test Power Cleaner for colourfastness on an inconspicuous area)
- Finally, use Canvas & Cotton Protector to make the tent watertight again.
