That's a nice box to find.
(Yes, I see it.)
TROUSER EXPERIMENT REPORT
Warning: Spoiler! (Click to show)
In Phase 1, now complete, I tested the following:
Enzyme based detergent (Tide)
Non-enzyme based detergent (wisk)
In addition to straight soaks, I also ran one set of trou in each of the above soaks with a pre-treat of eachn of the following (each on different trou)
Lanolin based hand cleaner
As a method, the pretreats soaked for 48 hours. For the soaks themselves (again, 48 hours), the trou were suspended from the left leg, dipping the right waistband only into the soak, allowing a comparison of unsoaked and soaked. I also assigned each lining a rating from 1-10 before the soak, with 10 being the most severely stained. I measured outseam and cuff width, to track shrinkage.
I was planning a full scientific writeup, but
Suffice it to say that most did nothing or very little. Enzyme/Tide was not color safe. Non-enzyme/Wisk seemed best. Damage to the wool seems to be minimal, if the proper steps are followed, including: Rigorous rinse soak to remove the residual detergent; slow, careful drying, NOT hanging the garment or otherwise putting it under stress or pressure (i,e, no wringing or strong agitation; dried laid flat). If followed, the results with Wisk can be quite dramatic. One pair went from a soil level of 8, I think, to a 1 or a 2.
Note that metal clasps rusted in the various soaks.
Results of Phase 1 can be viewed here:
Phase 2 will be to break all trou into piles of similar color. Then all trou will be soaked in wisk, full emersion. This will re-test color fastness (since I only ran wisk on a limited subset of colors).
No need to thank me; just send me your NWT E. Marinella and E.G. Cappelli ties and John Lobbs.
Last week for the hell of it I threw a pair with a stained crotch into the washer just to see what would happen. The stain came out. I had to take them to the dry cleaners to be pressed because the inside of the pants were so badly wrinkled.
