Hi, just aquired a tub of the above. Im just wondering two things. Its marked woolsafe, but just how good a cleaner is it?
Secondly, with regards to powder products, just how long do they keep? Ie for how long are worth using? I have no idea how old this tub is, it was part of a job lot i bought. Never heard of it before. I usually use liquid f90 on wool (at correct dilution).
