Professional Application Tips

Tip 1: Correct dosage
Less is often more. Apply the product specifically to the stained areas. A thin layer is usually sufficient.

Tip 2: Observe dwell time
Give the product time to work. For fresh primer, 2-3 minutes are sufficient; for dried primer, up to 5 minutes.

Tip 3: Right tools
Use lint-free cloths or microfiber cloths. For hard-to-reach areas, we recommend the 50ml pen.

Tip 4: Combination with other products
For adhesive residues, use our Adhesive Residue Remover, for glazes, the Glaze Remover.

Tip 5: Storage
Store the product in a cool, dry place. Close the bottle tightly after use.

Frequently Asked Questions about the 500ml SPECIAL

How much area can I clean with 500ml?
This depends on the degree of contamination. For spot stains, 500ml is sufficient for approx. 50-100 m² of area. For large-area stains, for approx. 20-30 m².

Can I also use the SPECIAL for light stains?
Yes, but for light stains, the 750ml Standard Version is more economical.

Is the SPECIAL more aggressive than the standard version?
No, it just has a higher concentration of active ingredients. It is just as gentle on the skin and environmentally friendly.

Does it also work on old, dried primer?
Yes, that's exactly what it was developed for. Even primer that has been dried for weeks can be removed with it.
