Strengthening a very light, solid colored silk dress I have shown courage, and despite the reference to the bottle "Not suitable for silk" with this product achieved an optimal result.
I proceeded as follows:
1) Soak the dress completely in water
2) Then put the wet dress in the starch solution prepared according to the manufacturer's instructions, in which I have added an additional tablespoon of vinegar essence, gently swirl the dress in the solution for even distribution.
3) hang dress dripping wet
4) Then iron damp dress
For me, the result was great.
