If you are really concerned about excess fluid somehow getting into the suspension of the cartridge, what you can do is use the applicator to brush the fluid onto the black handled brush that comes with the Stylast. Then use the brush to apply the transferred Stylast to the stylus. I can't believe there could be enough excess fluid this way to cause any concern.
I've been using Stylast for years and have never had any problems with it on the three Lyra cartridges I've used it on.
