When performing egg washes for Monarch eggs, instead of using a coffee filter, try using a non-gauze milk filter. These can be purchased from Ken Ag (800) 338-7953. They are 6-1/2″ round disks that are used to filter the milk as it goes into a bulk storage tank. These filters hold up better than coffee filters and let the liquid flow through faster than coffee filters. The Ken Ag company is located in Ashland, Ohio and price is $3 for 100. Other dairy supply companies sell these filters, too.
This tip came from Dale Belt of Dream-Away Acres, to Linda Rogers. Dale has good luck using these neat filters.
