    Default cleaning wool "4 loop" and synthetic fabric conical filters

    Hi from Missouri- Is it OK and safe to clean these filters with bleach/water solution? I know that soaps/detergents should not be used, but I believe bleach water would not leave a residue or taste, all would evaporate. We just made 3.5 gallons today of beautiful gold first run syrup before the snow hit. Filtering was a slowdown, lots of sugar sand so we used countless conical synthetic filters and were discussing how to get these filters clean.
    2020: 220 trees, most smaller than 20" diameter, made 25 gallons
    remote location in western Cole County

    Rinse them with hot water only. Do not wring them out.. Hang them up to dry. When I use my filters both the pre filter material and felt/wool I get them damp with really hot water before filtering the syrup. They seem to work better. I would not use any kind of bleach until you are done for the season, and very little. Make sue it is un-scented.

    I put mine in the washing machine on hot water and the light/gentle cycle with no soap or bleach. After they run I hang them to dry. They get a lot cleaner than just rinsing. I'm sure someone is going to gasp and post, "you should never put them in a washer", but I have done it for years and I still get clear syrup and nice clean soft filters. Oh I forgot these are all orlon synthetic.

    I do the same thing as Buckeye. It accomplishes the washing really well and without wringing. Super easy.
