Low foaming mildly acidic cleaner/brightener for aluminum.

FREICLEAN 61-LF is a mildly acidic cleaner/brightener for aluminum and can be used on other metals (however, may have a shorter service life when used on ferrous materials). FREICLEAN 61-LF is designed for Spray or immersion applications and is a liquid material for ease of handling.

All equipment used for processing and handling this product should be stainless steel or plastics that can handle the operating temperatures during processing. Carbon steel should not be used as the material will attack it.

The cleaner solution is usually built up at concentrations of 1 to 10% by volume, depending on the soils to be removed. Cleaning temperatures can range from 90°F to 180°F with immersion times of 2 to 10 minutes. For Spray applications use a build up concentration of less than 5%. Higher temperatures in the sump will result in lower foam build-up.

The concentration of the FREICLEAN 61-LF solution may be determined by the following method:

Pipette a 2 ml sample of the solution to be tested into a 300 ml Erlenmeyer flask or suitable beaker and dilute with 200 mL of D.I. water. Then add 5 to 10 drops of Indicating Solution 3 (Phenolphthalein) and titrate the cloudy white solution to the first pink endpoint with Testing Solution 11 (0.1N NaOH).

When testing a bath used to clean aluminum or iron add 10 ml or more of Testing solution
#37 (25% Potassium Fluoride dihydrate solution.) before titrating the endpoint.

% by volume FREICLEAN 61-LF = 0.765 x mL’s Testing Solution 11
