Do you want to know if you can use Sprayhood & Tent Shampoo yourself and get a good result? Below you will find a clear step-by-step guide to safely and effectively clean your fabric.
Do I need to wet the fabric before using Sprayhood & Tent Shampoo?
Yes. Always wet the fabric first with lukewarm water.
A damp surface allows the shampoo to spread more evenly and work more effectively. Remove loose dirt beforehand with water and a soft brush.
How do I apply Sprayhood & Tent Shampoo correctly?
Apply the shampoo generously to the wet fabric.
You can use:
- a spray bottle
- a soft brush
- a sponge
Distribute the product evenly across the entire surface. Work in sections so you do not miss any areas.
How long should Sprayhood & Tent Shampoo work?
Let the shampoo sit for about 20 minutes.
This gives the product time to loosen dirt from the fibers. Make sure the fabric does not dry during this time.
Do I need to brush, or is rinsing enough?
Brushing is important for a good result.
Use a soft brush to gently loosen the dirt from the fibers. Rinsing alone is usually not enough when visible contamination is present.
How should I rinse out Sprayhood & Tent Shampoo?
Rinse the fabric thoroughly with clean water.
Make sure no shampoo or dirt residues remain. Leftover residues can cause marks or attract new dirt. Work from top to bottom for an even result.
What should I do after cleaning the fabric?
Allow the fabric to dry completely.
After cleaning, the fabric is clean but not yet protected. Cleaning is step 1 in the Ultramar maintenance process:
- Cleaning – remove general contamination with Sprayhood & Tent Shampoo.
- Stain removal – if necessary, treat deeply embedded or stubborn contamination locally.
- Protection – after complete drying, apply a suitable protector to restore water repellency.
If you skip the protection step, water repellency will decrease and the fabric may become dirty again more quickly.
Can you do this yourself?
Yes. Sprayhood & Tent Shampoo is developed for home use. You do not need specialist knowledge or professional tools. With water, a soft brush and enough time, you can achieve a solid result yourself.
In short
Wet the fabric first, apply the shampoo generously, let it sit for 20 minutes, brush gently and rinse thoroughly. Allow the fabric to dry completely and then reapply protection for a durable result.
Ultramar helps consumers clean, maintain and protect boat covers, tents, convertible roofs, plastic windows and other outdoor materials themselves, using PFAS-free maintenance products that are easy to use at home and based on a proven three-step maintenance process.
