I re-applied lanolin to my Trapper Point blanket a week ago. This blanket was made in the mid 1920's and is irreplaceable.
You may want to practice with an old sweater until you get comfortable with the process.
This method can be used on any wool item you want rain proofed.
The Eucalan wool wash already contains natural sheep lanolin but we are going to add more.
This recipe is especially good for older point blankets.
Things I used:
Eucalan wool wash - Lavender.
1.4 oz tube of HPA pure lanolin. Doesn't have to be this brand.
Large extra fine pet grooming slicker brush.
Bathtub!
Clean 5 gallon bucket
USGI hammock
Drying rack
Steps took:
Take the Eucalan bottle and squeeze about half the tube of HPA Lanolin inside it.
Set in the sun to warm and shake until mixed properly. Or if you do this in winter warm the Eucalan bottle with hot water.
No solvent needed. The Eucalan does the work.
It does not take a ton of heat to melt the extra Lanolin into the Eucalan wool wash.
A clean bathtub about half way filled with hot water less than 100*f. In my case by the time the tub is at the level I need it the water isn't over hot, it's just right at 85*.
I guess it depends on your tub, ambient temps etc.
Add 1/2 cup of your Eucalan/lanolin mixture to the tub and stir it around.
Place the blanket into the tub and GENTLY push it around until it's completely submerged. Don't agitate it too much.
After the tub water has cooled to ambient air temp. (about 40 minutes) I take the wet blanket and place into a clean 5 gallon bucket.
Then outside I put the wet blanket in my USGI hammock and swung it around until it was as dry as it could get. You'll get dizzy...
Never wring out or squeeze by hand.
From there I spread it out flat in the shade on my lawn. Make sure it's a nice warm day when you do this.
Flip it over every so often.
After it was completely dry I rolled it up and put it in the freezer for a couple days to kill any moth larva or other things that may have climbed onto it.
The final step is to hang the blanket on a strong rack and use the pet grooming slicker brush UPSIDEDOWN. Brush it the same direction the nap goes. This way you will NOT lose any of that precious nap.
