Want to know how much Ultramar Power Cleaner you need for your tent, boat cover or fabric convertible top? Below you’ll find clear, practical guidance so you can order the right amount.
How much Power Cleaner do I need?
The required amount depends on three factors:
- The level of contamination
- The thickness and condition of the fabric
- Whether you are treating the entire surface or only specific areas
Average guideline for heavy contamination:
- Awning (polyester): approx. 1 litre
- Boat cover (sloop): approx. 1 litre
- Convertible soft top: approx. 1 litre
- Small sprayhood or spot treatment: approx. 0.5 litre
If you are only treating specific problem areas, you will naturally use less.
Is 1 litre of Power Cleaner enough for my application?
In most cases, 1 litre is sufficient for a full deep cleaning of an average-sized convertible top, boat cover or awning.
You use Power Cleaner specifically for:
- deeply embedded stains
- stubborn contamination
- difficult-to-remove discoloration
- heavy contamination
If you use it only on affected areas after regular cleaning, 1 litre can often be enough for multiple treatments.
Very old or heavily contaminated fabric may require more product.
Why does heavily soiled fabric require more Power Cleaner?
Deep contamination often sits in multiple layers within the fibres.
Power Cleaner needs sufficient product to gradually loosen and remove these layers. In some cases, multiple applications are necessary for optimal results.
Older or dried-out fabric may also absorb more product than newer or well-maintained material.
Can I use Power Cleaner locally?
Yes. Power Cleaner is specifically developed as a targeted stain remover.
After completing the first cleaning step with Sprayhood & Tent Shampoo, you apply Power Cleaner only to the areas where contamination remains.
This approach ensures efficient use and prevents unnecessary product consumption.
Is it useful to keep Power Cleaner on hand?
Yes, that is often a smart choice.
Deep contamination can occur unexpectedly due to prolonged moisture, storage conditions or intensive use.
Having Power Cleaner available allows you to act quickly before stains become more difficult to remove.
Does Power Cleaner fit into a complete maintenance routine?
Ultramar works with a fixed 3-step maintenance process:
- Cleaning – Base cleaning with Sprayhood & Tent Shampoo
- Stain Removal – Deep cleaning with Power Cleaner
- Protection – Protecting the clean fabric with the correct Ultramar protector
If you want the best long-term result, follow all steps in the correct order.
Ultramar offers maintenance bundles that combine the right products. Bundles are often more cost-effective than buying products separately and ensure you don’t run out during treatment.
Do not be too economical with product use. Using too little can affect the result. Choosing slightly more product is often more practical and leftover product can be used for future touch-ups.
Summary
For most standard applications, 1 litre of Ultramar Power Cleaner is sufficient. For older or heavily contaminated fabrics, more product may be required, especially if multiple treatments are needed.
Use Power Cleaner selectively after the initial cleaning step and always re-protect the fabric afterwards for long-lasting performance.
Ultramar helps consumers clean, maintain and protect boat covers, tents, convertible tops, plastic windows and other outdoor materials themselves with PFAS-free maintenance products that are easy to use and designed for home use, based on a proven three-step maintenance process.
