Dekalin DEKACLEAN Ultra 1 l - fast-drying cleaner and degreaser before bonding and sealing in motorhomes
- Fast, strong cleaner that degreases metals and plastics before bonding and sealing. Evaporates without residue and also removes uncured MS compounds, 1 l bottle.
Dekalin DEKACLEAN Ultra is a fast, strong multi-purpose cleaner. It dries quickly, leaves no residue and is suitable for many surfaces. The manufacturer intends it mainly for cleaning and degreasing substrates before bonding and sealing with Dekalin products. After manufacturing, metals and plastics usually carry a greasy film, which DEKACLEAN Ultra dissolves without affecting the subsequent curing of the compounds.

Key features
- Flashes off quickly, approx. 3 minutes, without residue
- Does not affect the curing of adhesives and sealants
- For aluminium, steel, copper, brass, painted and powder-coated metal
- For glass, GRP, ABS, PVC, PMMA, polycarbonate and polyurethane
- Removes uncured MS compounds from substrates and tools

Use in motorhomes and caravans
DEKACLEAN Ultra is the first step of every job with DEKASYL and DEKASEAL adhesives and sealants: before fitting a roof light, bonding a solar panel, SAT antenna, trim or profile. It also removes fresh, uncured MS compound residues from surfaces and tools.
The 1 l bottle is intended for the workshop and larger jobs. For the on-the-road repair kit the DEKACLEAN Ultra cloth in a sachet is more convenient.

How to use, step by step
- Moisten a clean, lint-free, colourless cloth with the cleaner.
- Fold the cloth several times and wipe the surface in one direction only.
- Turn to a fresh side after each wipe so that dirt is not transferred back.
- Wait approx. 3 minutes to flash off, then apply activator or compound.

Can I use an ordinary thinner or alcohol?
The manufacturer recommends DEKACLEAN Ultra because it leaves no residue and does not affect the curing of DEKASYL compounds. Other products may leave a film that weakens adhesion.
