Abrasion damage is often mistaken for colour loss. Classifying silk with robust loads but protecting it with a net bag can cause abrasion damage. This can be identified by viewing the affected area obliquely across the fabric. Small local areas of abrasion damage can be masked using a very light spray of zip lubricant. Larger areas should be treated by cleaning the garment in a solution of suede and leather oil or liquid paraffin (available from the local pharmacy). This solution should be in the ratio of 7 fluid ounces of oil to around 5 litres of solvent. Specialist products for application from an aqueous solution are also available.
Removing stains from silk requires great care. I recommend avoiding kit chemicals unless they are specifically recommended for use on silk. Use pure chemicals, after testing for colour safety. They are much safer on silk than kit products. This applies particularly to acetic acid.
Pre-spotting should be avoided as it is not possible to test externally for the conditions that prevail during the cleaning process. Where appropriate use localised pre-cleaning stain removal techniques on the spotting table. Make sure the treated area is dry before cleaning.
The following points are vital.
Inspect garments at the counter for signs of abrasion damage.
Designer items are high risk – the higher the value, greater the risk.
Make a separate classification for silks – lightweight, delicate fabrics.
Never place a silk garment in a net bag and clean it with a normal load of work.
Never use a spatula for stain removal – tamp with a soft brush.
If you dryclean a silk always use a gentle cycle suitable for garments with a circle P underlined label, if possible with interrupted cage rotation.
