Clean 'n Etch :

Product Description
Clean 'n Etch is a concentrated, water-reducible phosphoric acid and detergent blend formulated to both clean and profile concrete, masonry, steel, galvanized and zinc surfaces before applying a coating, stain or sealer. Clean 'n Etch is an economical concentrate which is diluted with water before use. The favorable safety and environmental attributes of Clean 'n Etch reduce liability and improve productivity without a performance sacrifice.

Advantages
On concrete, Clean 'n Etch reduces preparation time by eliminating the separate pre-cleaning and rinsing operation before acid etching.

On Passivated Galvanized, Clean 'n Etch degrades the passivation coating on galvinized steel and impoves coating adhesion.

On steel, Clean 'n Etch cleans, degreases and provides a phosphate conversion coating for improved corrosion resistance and enhanced coating adhesion.

Clean 'n Etch has no acidic vapors eliminating the accidental corrosion of ductwork, electrical contacts in machinery and equipment and other sensitive parts.

Additionally, Clean 'n Etch is ideal for use in areas with limited ventilation such as basements, swimming pools, containment areas and pits.

Clean 'n Etch is odorless, non-flammable and is safe to use near vegetation.

Uses
Concrete
Cleaning, degreasing and profiling the surface to prepare it for coating, staining or sealing. Removes many "cure & seal" compounds.

Masonry, Brick
Cleans mortar joints, removes excess mortar and dissolves efflorescence

Steel
Cleans, degreases, derusts and creates a phosphate conversion coating.

Galvanized
Removes the passivation film on galvanized steel to improve coating adhesion

For Concrete Floors

1. Select proper dilution (see Dilution Guide).
2. Add concentrate to water and mix. If available hot water will accelerate cleaning and etching.
3. Sweep loose debris. Dampen surface with water
4. Apply solution to a 10' x 10' section so that a uniform film of the solution covers the area. Note: If no bubbling occurs, a coating, sealer or curing compound is preventing solution contact with the concrete. Remove before reapplication.
5. Allow 5 minutes contact time and scrub with a broom or brush until the bubbling stops
6. Triple rinse with water and scrub while rinsing.
7. Allow surface to dry thoroughly and check the pH of the surface with pH indicator. If the pH is below 7.0, repeat steps 5 and 6.

For Steel
Brush or spray solution onto surface or immerse parts in Clean 'n Etch solution. Refer to Dilution Guide for recommended concentrations. Allow 1 - 3 minutes contact time and rinse with hot water or wipe and force dry immediately.

For Shiny Galvanized
Spray 2 parts water:1 part Clean 'n Etch solution onto surface. Allow 5 - 10 minutes contact time, rinse thoroughly with water.

For Hot Water Parts Washing:
Concentration: 1 oz. to 4 oz. per gallon
Temperature: 120°- 180°F
Pressure: 800 - 3,000 psi

1. Thoroughly wet all surfaces of small parts. For larger parts, treat one section at a time working from top to bottom.
2. Spray each side of the part with the wand tip 6" - 12" from the surface A 45° contact angle provides maximum soil removal. Use an overlapping spray pattern to insure complete coverage. Tilt parts to aid draining and reduce drying time.
3. Rinse with hot water to prevent flash rusting.

For Derusting Steel Surfaces
Spray 2 parts water:1 part Clean 'n Etch solution onto surface. Allow 5 - 10 minute contact time. Rinse surface with warm or hot water. Heavily rusted parts may require scrubbing while rinsing.

Dilution Guide
Clean 'n Etch concentrate is intended to be diluted before use. Dilution rates vary with substrate, surface conditions, application method and the results desired. To determine the dilution for a specific job, mix test solutions based on the chart and compare the effect of different solutions.

Coverage Calculator

To determine how much Clean 'n Etch will be needed for a specific cleaning job, use the following guide:

To determine the approximate gallons of Clean 'n Etch required for Concrete:

1. Select Light, Medium or Heavy Duty from the chart (below).
2. Find the Square Feet of Coverage closest to the Total Surface Area in Square Feet to be cleaned.
3. Use the number in the "Gallons of Concentrate" column for the number of gallons needed to clean a flat, smooth surface using a low pressure spray applicator.

Note: For rough, porous or corrugated surfaces, multiply gallons X 1.2.

For high pressure spray application multiply gallons X 1.3.
