Rust Removal Procedures

1. Assemble all chemicals and custodial hardware prior to beginning procedures. Read safety instructions on MSDS’s and chemical product labels and comply as directed.
2. Move all movable objects from area(s) to be cleaned.
3. Sweep area to remove all loose soil. Use scraper to remove gum, etc. Dispose of litter.
4. Place Wet Floor Signs at access area to foot traffic.
5. Position a Track Off mat at entrance area to be cleaned to serve as a holding area for wet equipment and to clean workers feet prior to entering cleaned area.
6. Mix Ultra Floor Care ‘Stripper’ at 1:3 (43 oz per gallon of water) or at a pre-determined dilution (see note below), in a clean mop bucket with wringer or suitable sprayer.
7. Fill a second suitable container with Ultra Floor Care ‘Neutralizer’, undiluted. Depending upon the size of the area to be cleaned, the container could be an acid resistant trigger sprayer, watering can or other similar vessel.
8. Apply ‘Neutralizer’ to a manageable area and allow 10 to 20 minutes swell time. The ‘Neutralizer’ may effervesce and if this occurs, allow effervescent action to subside before continuing. Do not pick up ‘Neutralizer’. If are(s) begin to dry, begin next step immediately. Do not allow ‘Neutralizer’ to dry-back.
9. Apply ‘Stripper’ to area(s) ‘Neutralizer’ was applied to while still wet using a dedicated stripper mop. Allow 5 minutes dwell time.
10. Light machine scrubbing or hand scrubbing may be required in areas with a high concentration of rust. Visual evidence of these possible requirements will be obvious.
11. Pick up solution with a wet vacuum or squeegee into a sanitary sewer. Do not dispose of solution in a storm sewer.
12. Continue on in this fashion until entire area(s) are completed. Inspect to ensure that complete removal of rust has been accomplished. If necessary, repeat the procedures as and where required.
13. Flood mop, rinse, and hose or pressure clean the area(s) with cold water. Remove excess water with floor squeegee or wet pick up vacuum.
14. If floor finish or seal is to be applied to the surface, check the pH of the surface and adjust as necessary to bring floor to a neutral (7 to 9) pH range.

Alternate Procedure Options
Note: Undiluted ‘Neutralizer’ will etch polished marble, granite and all plated metals or alloys. Do not perform this procedure without proper care and caution to cover/protect these substrates to guard against contact with ‘Neutralizer’

Caution: If heavy soil loads and / or heavy rust deposits are encountered, pre-test ‘Stripper’ at about recommended dilution to determine whether dilution is effective. If required, increase dilution to an acceptable strength to accomplish task easily, effectively and in one application.
