How To Clean Sofas – The Shrinkage Test
This shrinkage test is usually carried out on cotton and button backs, pleats, and sofas that have been reupholstered. This is test is part of a wider survey we should carry out before any cleaning is done. As a professional upholstery cleaner you should have this survey recorded for insurance reasons. Any issues found with shrinkage or any of the other areas within the survey should be signed off from the customer.
As well as all the risks involved with cleaning upholstery you should always set expectations for the results. Dirt can hide a lot of wear and this can be very shocking to people. Some of the other areas that we would want to talk to customers about is. Colours loss due to sunlight, or abrasions. weak areas around the seats and arms of the sofa. stains, any existing damage, issues with the stuffers and fillers.
