naphtha + mineral oil / silicon + naphtha

[Ojaituner2@AOL.COM]

Hello List,

Would like to weigh in on this subject. I too saw demonstration put on by 
Wurlitzer at a National back about 1978. 
I have used the silicone naphtha treatment on a regular basis to deal with 
sluggish centers and have never experienced any of the problems for which it 
has been labeled with.
This stuff works when nothing else will and I have also had sustained success 
on verdigris action centers where I have been able to follow the treatment 
for over ten years.
I also feel that it makes shrinking centers more stable and seems to help in 
not over shrinking.
The main concern is to use it in open air or with good exhaust and give the 
action a chance to air out well before putting it back in the piano. I always 
bring the action back to the shop where I can tighten the flange screws first 
and blow the dirt out so that I am not washing dirt and dust into the works.
Thankyou to the list, for all the good info all around.
