Shall I rinse the garment after washing with wash-in waterproofing?

For the OrganoTex Wash-In Textile Waterproofing available in Reima stores and online, detailed instructions can be found online. The garment is first washed normally, then washed briefly using the Waterproofing liquid instead of detergent, and then dried in a warm room, drying cabinet or tumble dryer. If you do the washing and waterproofing by hand, use protective gloves and rinse the garment thoroughly.
