Troubleshooting My Philips Garment Steamer leaves stains on the garment If your Philips Garment Steamer leaves stains, or you notice impurities coming out from it, there might be a simple solution. Just read along. The steamer needs to be descaled If your steamer is not descaled regularly, it is normal for scale to build up in your garment steamer, and this can cause it to release some impurities or produce stains. To solve this, you should descale your steamer. The descaling process depends on your product and series.
