Rinse heavy mud off trailers with clear water (a soap solution will hinder the effectiveness of the Aluma-Brite).
Apply the foam generously to one side, back and front of trailer.
IMPORTANT: Spray from bottom of area to top. DO NOT get on painted surfaces.
Allow it to penetrate for 3-5 minutes. Flush off foam with high pressure washer, holding end of wand 1-3 feet away. Repeat procedure on the other side, front and back of trailer. After rinsing, wash trailer with a light solution of Power-Pro 2000 to neutralize the acid.
Use 4 oz to 1 gallon of water for pail and brush washing.
In foaming units, set dilution screw until rich foam appears.
Note: **High acid content. If splashed in eyes or on skin, flush with water for 10-15 minutes and seek medical attention.**
