UPDATE. On my SML. alto the lower stack D and E keys started sticking again so that’s 9 months or so. What I don’t know is whether I put to little or too much as they are the only 2 that show any signs of it returning and I had all the springs retensioned in November Too make them faster.
so I drenched one and went sparingly on the other.
for sticky pads i always used to use lighter fuel until the sainted willy garnett in putney gave me a little colman's english mustard bottle containing paraffin. since then i always tell people i clean them with mustard. paraffin works really well and seems less drying than lighter fuel.
