[Harp-L] Re: Ultrasonic Cleaners

Hello, Ultrasonic Harpers.
 
An ultrasonic cleaner is a machine that uses a suspended parts basket  
containing whatever you want to 
be cleaned, submerged into a cleaning solution in a tub. The basket  holds 
the pieces while the vibrating machine creates bubbles in the  solution, 
cleaning the materials. Ultrasonic cleaners don't damage any 
materials. No scratches, breaks, etc. Just a total cleaning of the  surfaces.
 
Ultrasonic cleaners are not recommended for use with porous materials (wood  
combs, wood covers,etc.) 
The ultrasonic cleaner machine may damage porous materials. It's designed  
for use with non-porous materials, like synthetic harmonica combs, reeds, reed  
plates, harmonica covers, screws, mouthpieces, slider parts. 
 
The Ultrasonic cleaner should not be used on enameled (painted)  harmonica 
covers, wood combs or wood covers.
 
I found a good model at _www.micromark.com_ (http://www.micromark.com) .
 
Look in the section titled "Cleaners, Solvents, Etc." You'll find 2 models,  
one for small parts, and one for larger parts. For me, the larger one works  
well. It can hold items as long as 11.5", and as wide as 4". 
I don't remember the measurements of the smaller model, but it would  
probably hold items less than 6" 
long.
 
The larger machine sells for about $250, and the smaller one is priced  under 
$100, if my memory is correct.
 
Micromark is a small-parts and small-tools company, doing business mainly  
with model railroaders, model airplane hobbyists, etc. But it sells many tools  
of high quality, useable for harmonica maintenance and repairs.
 
I'm not affiliated in any way with the Micromark company.
