Forget the Scotchguard! Go buy yourself a gallon of Thompson's Water
Seal; yes, the stuff for wood decks, etc. Then, spread the blanket out
on the floor, or a piece of plywood over 2 saw-horses (that works better
if you aren't up to crawling around on the floor!). Get a big paint
brush, dump some of the Thompson's into a small container and paint
This has worked on any blanket that is NOT a 100% nylon exterior. The
nylon won't absorb the Thompson's but any natural or part natural fabric
will very well. I've used this on New Zealand rugs that I washed in the
washing machine and then dried in a dryer. I just don't think that
field washing gets them clean enough after a whole Winter! So, I drag
them to the laundromat in the Spring when the horses are through with
them and wash them, dry them, then paint with 2 coats of Thompson's.
Have also made some cheap canvas blankets and a couple of cloth ones,
including a Baker blanket, waterproof the same way. Always use 2 coats,
let dry in between coats, and the blankets will last all season.
Have used this too on Gortex stuff that had lost its waterproof
capability after one too many washings.
Hope this helps,
