Hello,
What type of cleaning and rinsing solutions should I use in my L&R Precision Cleaning Machine? It is the type with the little basket that spins in three jars of solution and then in the dryer. I see that L&R makes solutions for ultrasonic machines; are they ok for my machine? Thanks,
Pete Belmonte

peter i use L&r # 111 cleaning solution and #3 rinsing solution in the l&r i have (which i just started using) ..I also use a ultrasonic cleaner and these work good in both machines..

Samie,
Thanks for the info. I see that S. Larose sells both these types, too. I guess that's my next purchase! Thanks again,
Pete

I've heard a lot of talk about ammoniated solutions destroying (stress fractures)on watch parts. Due to this I stay away from them. Do any of you have an opinion on this?

My opinion is, nothing cleans as good as ammoniated solutions.

I'd also like to clean some watches that I've taken apart, but I'm very worried about toxic fumes. Does anyone know exactly which of the cleaning/rinsing solutions (for the ultrasonic cleaners) are non-toxic, or if none are that, which are least toxic? What are the specific ingredients, and what is their toxicity?

In adidition and importantly, what precautions or protections do you use when the solutions are being used?

Thanks, Jessica

As far as I know all cleaning solutions should be used in at least a well ventilated area. In professional shops the use of ventilation hoods like the ones that are over stoves are used.

Jessica,
L&R Manufacturing Co. has posted a listing of Material Safety Data Sheet, which includes a a recommendation of "Exposure Control Personal Protection".

In the words of the great Steve Maddox..."any cleaning solution that is water based...you're asking for trouble"..what ever happened to Steve any way???...Tony c

Thanks, Wayne. I'll check their website (I assume they have one).

I'd be interested in knowing what precautions other people in the chapter take, assuming you don't use a hood, or have a professional business setting.
