Freiclean LSR-1 is an acidic cleaner developed specifically for cleaning scale off laser cut steel.
Freiclean LSR-1 is designed for immersion or spray applications and is a liquid material for ease of handling.

Fill the process tank to two-thirds level with water and add the required concentration of Freiclean LSR-1 with stirring. Bring the bath up to operating temperature and level.

Concentration can range from 5 to 20% by volume depending on the severity of the oxide and the amount of cleaning time available.

Temperature can range from 120°F to 140°F with process times normally in the range of 30 seconds to 5 minutes.

The concentration of the Freiclean LSR-1 solution may be determined by the following method:

Free Acid:
Pipet a 1 ml sample of the solution to be tested into a 125 ml Erlenmeyer flask or suitable
beaker and add 5-10 drops of Indicating Solution 11 (Bromophenol Blue) and titrate with Testing Solution 11 (0.1 N NaOH) to a blue-green endpoint (absence of yellow). Record the buret reading as the Free Acid.

% by volume Freiclean LSR-1 = 1.49 x mls Testing Solution 11

Ferrous Iron Content:
The concentration of ferrous iron in a Freiclean LSR-1 cleaning solution can be used to estimate when to dump the bath. Each application will have a ferrous iron level at which the Freiclean LSR-1 bath will become ineffective. This level can be identified through experience on the particular line.

Procedure: Measure a 10ml sample into a beaker and add about 15 drops of Testing
Solution #44, then titrate with Testing Solution #18 to a pink color that last 20
seconds. Each point (1.0ml) of Testing Solution #18 is equivalent to 0.1% iron in
solution.
