Why not use the soak-in version of Sawyers (aka "military style"). You
dilute the product 2:1 or 3:1 and let the clothing soak in the mixture as
long as you like (at least 2 hours).

Unfortunately, the soak-in  version is harder to find than the spray. REI
for example stocks only the spray, I believe.

It is sold online here:

But it has the *identical* ingredients as the spray, so you can always buy
the spray version but follow the instructions for the soak-in. Roll the
clothes into a tight bundle and tie with string. Put it in a plastic bag
(supplied with the soak-in product; find your own if using the spray-on).
Mix 6 oz. of the product with 12 to 18 oz. of water. Pour into the bag and
squeeze the contents so that the fluid fully soaks into the clothing. Wait
at least 2 hours. Then hang the clothes to dry.

Since the military uses the stuff at 80 times the concentration of the
civilian version, you could consider buying a lot of the civilian version
and using it at full strength rather than diluted. But that would be quite
expensive. Like  $35 for a single clothing set. Might last longer than the
diluted method however (6 weeks).
