Usage instructions:

Important warning: This is an acidic product. Always use appropriate personal protective equipment (PPE) including protective gloves and goggles! Before application, thoroughly test the product on a small, inconspicuous area.

1. Dilution: Depending on the degree of soiling, dilute the product with water in a ratio of 1:5 to 1:20 (e.g., 1 part Hull Precleaner Acid to 5-20 parts water). For extreme yellowing, a stronger dilution or undiluted product may be used (only with extreme caution and testing!).

3. Dwell time: Allow to dwell for 1-3 minutes. Do not let the product dry on the surface!
4. Mechanical assistance: In case of heavy deposits, use a soft brush or sponge for gentle mechanical cleaning to loosen dirt.
5. Thorough rinsing: Immediately and thoroughly rinse with plenty of clean water, ideally using a high-pressure cleaner, to remove all product residue and dirt. Ensure that water with the product does not run onto unprotected, sensitive surfaces.
