14.7.2.3 Spotting procedure
Correct procedure for spotting
It is recommended to integrate the three stages of spotting
• Brushing
• Special spotting
• Post-spotting
into the process of textile cleaning. Perform brushing and special spotting when examining
and sorting the textiles to be cleaned.
Brushing
Examine textiles for excessive dirt, particularly at collars, pockets, sleeves, and trouser legs.
If textiles are to be dry cleaned check them particularly for stains originating from food or
body secretions.
If the textiles are to be wet-cleaned check them particularly for greasy stains. Apply a
small quantity of brushing agent onto the stained areas and allow to react for 10-20 minutes
before loading the cleaning equipment.
Special spotting
Intensive staining found during the examination of the textiles can be treated with special
spotting agents. The stain substance must be identified and related to one of the following
categories:
• coffee, tea, fruit, red wine, grass, urine
• blood, food, pigments, sweat
• wax, paint, lacquer, make-up, pen ink, adhesives
Depending on the category of the stain substance, apply the special product with the
dripping spouts in the work bottle onto the stain and tamp it gently with a soft spotting
brush. Allow to react for 10-20 minutes before loading the cleaning equipment.
Post-spotting
Stains that could not be removed during dry-cleaning or wet cleaning with machines are
subject to post-spotting. Proceed as follows:
• Place the garment with the stain area onto the perforated vacuum surface of the
spotting table.
• Identify stain, drip appropriate product undiluted onto the stain and tamp it gently
with the brush.
• For stubborn stains, allow product to react for up to 3 minutes.
• Use vacuum to remove product and rinse spotted area with steam gun.
• Dry with compressed air, moving the air gun from the edges to the center of the
spotted area.
Hidden spot test
If it is suspected that a stain cannot be removed safely due to the textile material, the compatibility
of the spotting agent should be checked by applying a small quantity of the agent
at a hidden part of the garment. If the garment passes the test, the spotting agent is expected
to be successful without damaging the garment.
