Then remove the aqueous silica filter off by washing with distilled water until a neutral. Then remove the silica to bake at a temperature of 70 ºC is at 72 hours and then store in a jar used to moisture absorption.
Then the solution is secondary silica by washing with water until neutral. Then silica baked at a temperature of 70 ºC for 72 hours and then stored in a humidity chamber to the next.
The solution, so two silica out by washing with water until it is neutral. The silica to bake at 70 º C for 72 hours. And keep in the jar, moisture absorption for use the next job.
