A change in surface water beading does not, by itself, identify the next treatment. Finetrack’s current care FAQ starts with contamination and washing residues before discussing further water-repellent care. That sequence gives an owner a more useful question than simply which spray to buy.
Technique and structure
Finetrack identifies dirt, detergent components and additives such as fabric softener remaining on the fabric as possible contributors to reduced water repellency. It says removing dirt and rinsing detergent away can restore repellency in some cases. Cleaning and re-treatment therefore address different possibilities: a surface affected by residue does not automatically establish that another application is the first step. The maker’s conditional wording matters; washing is not presented here as a guaranteed recovery or a test of a garment’s waterproof performance.
Keep the care instructions with the garment
The FAQ advises detergent without fabric softener when using a commercial detergent, and goes on to describe additional care if washing is insufficient. This guide does not turn its ironing advice into a temperature rule for every garment. Check the actual product’s care label and the maker’s complete instructions before selecting a process.
For international readers
Use a change in beading as a reason to check contamination, cleaning and product identity. Overseas availability of the named care products or services has not been verified; this is not a claim that every fabric can be washed or heated in the same way.

撥水性の低下：加工剤を足す前に汚れとすすぎを確認
ファイントラックは、汚れや洗剤・柔軟剤などの残留が撥水性低下の一因になり、洗浄と十分なすすぎで回復する場合があると説明しています。これは回復を保証する話ではありません。同社FAQは洗浄、必要に応じた追加ケアを段階的に扱っています。個々の衣類の表示を確認し、撥水性の話を防水性能や全製品共通の加熱方法に読み替えないことが要点です。
