Create a Custom Saturated Surface Wiping System with PRO-SERIES Wipers and Charging Buckets from MDI


Read the instructions thoroughly before you begin

Fill out and apply the enclosed label or the label supplied by the chemical manufacturer

Place the desired amount of PRO-SERIES wipers into the bucket

Press firmly on the lid until it snaps securely in place

Locate the triangular cutouts on the rim of the lid and break the plastic tab

Detach the tear strip by pulling toward the front of the lid

Fold back the large section of the lid until it snaps into the open position

Prepare your liquid chemical according to the manufacturer’s Directions for Use

Slowly and evenly pour the solution over the wipers and allow 1-2 minutes for the wipers to become fully saturated

Always close the lid securely

Firmly grip and lift the large section of the lid to dispense

Quarterfolded towels may be refolded to expose up to eight clean surfaces for wiping

When the bucket is empty, lift the large section of the lid and refill with dry PRO-SERIES wipers

Be sure to add the same chemical solution indicated on the label
