Hello Albert,
I knew that you were most likely using the bottle that I'd sent you earlier. I hadn't considered suppying empty bottles; I know that my Distributor would be against it, and besides with my method, they are not required. In my opinion, we have designed a product that works well as it is.
My method, Albert, is very close to yours: I remove the brush cap, clean the stylus, then squirt my LP#9 brush off with just a few drops of Super Vinyl Wash, followed by the pure compressed air. This works great, keeps cross contamination very low and avoids the possibility of bottle polymer contamination. I'd hate to see someone repackage my product, chose an improper bottle, and ruin what is already a great product. Glass is still the best choice for the LP#9 solution, which is why we use it. Glass is more expensive, but is the best suited container considering the composition of the solution.
To avoid chemical contamination, we have not only spec'd out the brush material, but the bonding glue for the brush and the cap material as well. We've looked at contamination issues from many angles on all of our products.
Most LP#9 users just use it as it was intended, removal of the brush, cleaning the stylus, and placing it back into the bottle. I've know several that use 2 bottles of LP#9, one for cleaning the stylus, one for cleaning the brush. I've also heard that some drip the LP#9 fluid over the cap brush to rinse it after use. Both of these methods may work well, but sound like an expensive approach of brush cleaning.
To the many LP#9 users worried about cross contamination, try my method, it works well.
Kind regards,
