Mice got in Lascalas


Recommended Posts

I recently bought a pair of 1986 Lascalas and am in the process of sprucing them up. I've removed the network, tweeter, squawker and woofer from one speaker so that I can repair and refinish the cabinet. When I removed the woofer access panel I found that mice had been in the speaker.

 

The mice left droppings inside the cabinet and dirtied the woofer. Luckily, they didn't chew anything. I can clean the cabinet easily enough, but I'd like recommendations on how best to clean the woofer.

 

I'm leery of using a vacuum for fear of tearing the cone. I was planning to use a dry paintbrush, followed by a dry microfibre cloth to wipe the obvious dirt off the woofer cone. However, the cone has some areas of discolouration, I''m guessing from mouse pee. I was thinking I'd attack those areas with a damp cloth. 

 

Apart from the dirt, the woofers don't appear to be damaged, so that I'm hoping that a good cleaning will take care of things. I'd like to avoid having to re-cone them.

 

I'd welcome any suggestions on how to clean the woofers.

I would be leery of wetting the cone too much. Some others with restoration experience may have more precise recommendations.

 

I do advise wearing an good mask and eye protection and latex/vinyl or nitrile gloves when cleaning areas contaminated with rodent droppings. In my part of the country the rodents carry various viruses (Hanta; West Nile; etc.) and these may be transmitted by the urine and feces.

 

Enjoy the ‘Scalas!

 you  can  blow air on the speaker while using a soft  brush , so an air hose can  do , by adjusting the air pressure   stay clear of the dust cap , except with the brush  then , use some  diluted Detol cleaner on a microfiber cloth and gently wipe the cone ,, do the same inside the dog house

Randy, do you mean Dettol? I had never heard of that before.

 

I would think you would definitely want something that would neutralize the urine and not attack the paper. Those woofer cones are pretty tough and durable, though.

As @JBCODD said above, wear a mask and gloves when cleaning up rodent droppings.  My nephew was hospitalized recently with a life threatening virus (leptospirosis) contracted while cleaning up a rats’ nest in Chicago.

 

Thanks to both of you for highlighting the need to take precautions when cleaning up the mouse nest.
