TITLE SPOTTING PRODUCTS AND PROCEDURES
FOR HYDROCARBON SOLVENT SYSTEMS

The purpose of this Technical Report is to remind all hydrocarbon solvent cleaners of the proper use of spotting agents and prespotters. The proper use of spotting agents is important to prevent contamination of the drycleaning solvent. For example, drycleaners often use an oily type paint remover as a prespotter, which can lead to the hydrocarbon solvent taking on the characteristic odor of the paint remover. Garments processed in the contaminated solvent may also take on this objectionable odor. Over use of solvent-containing products, such as paint removers, can also lower the flash point of the hydrocarbon solvent. Lowering the flash point of the solvent adversely affects the fire safety of the system.

Proper spotting procedures are the same regardless of the drycleaning solvent of choice. Universally, drycleaning clinics and courses teach the cleaner/spotter the following procedure:

Select the proper spotting agent for the stain.

Apply the spotting agent to the stain.

Dissolve or break up the stain with the proper tool and mechanical action.

Flush the stain and spotting agent with a volatile dry solvent (VDS) if a dry-side spotter was used or with water or steam if a water-based spotter was used.

Finally, dry the treated area with air and vacuum before cleaning the article.

If a wet-side spotting agent was used it is recommended that Stamford SSS be applied as a leveling agent to prevent redeposition.

The above general procedures should prevent solvent contamination by spotting agents and allows cleaners to use the same spotting agents for all drycleaning solvents.

In general, prespotting agents are formulated specifically for drycleaning solvents. Stamford OGR-GES was formulated for use in all petroleum systems including the new high flash hydrocarbon solvents.
