Ok, I have been working with hanes men's undershirts, just to test out the whole salt soak thing...to make a reg. tee have a vintage softness.
At first I attempted the sodium carbonate & salt in the washing machine, did it about 4 times...shirts still stiff.
Right now I have a few shirts soaking in the salt and water for the past day or so...letting them soak for 3 days.
The shirts are 100% cotton and I am wondering why this has not worked yet. I am doing this from home, am not interested in attempting an enzyme wash myself and was wondering if anyone knew a sure way to turn a regular tee vintage tee soft from home...even feeling the tees that I currently have soaking, feels like they are still rough.
Also, I am doing some tie dye designs and if I find a way to soften the shirts, do I soak them first then dye them or should they be dyed first??
Thanks, hope this made sense
Vintage salt wash or new tshirt...help!
