Only one Metho that I know of. Look on the Internet you will find recipes to make Wool Wash. I have made a few times and it was LuxFlakes and I can’t remember if a cup of flakes so best to look on the internet but it makes a bit and depends how many times you will need it and if not it depends if worth all the mucking around making or just buy a bottle of Wool Wash.

Thank you everyone Ellen exactly what methylated spirits do you use?

Wpw, so many useful uses for metho. I learn something new every day

PS. I’ve no experience with using lanolin for this

Do not make my own wool wash as there are plenty of good ones to purchase in store.

Wool Wash Recipe

Pure Soap Flakes ½ packet (300gm)
Methylated Spirits 1 cup (200ml)
Eucalyptus Oil 50mL

Wool Wash Recipe

Mix methylated spirits with soap flakes. Add eucalyptus oil and stir.
Store in wide necked screw capped jar (large coffee).
Use one tablespoon mixture per garment. Dissolve in small quantity hot water and then pour into lukewarm wash water.
Hand or machine wash on wool cycle.
No need to rinse unless white garments are to be stored for a long period (rinsing reduces the risk of yellowing).
Squeeze and roll in towel to remove excess water.
Keep garments in shape while drying out of direct sunlight.

Never heard about using it in washing ( only to clean floors or glass)
