MsSha, these questions about cleansing AFTER cleansing, throwing away even the cloths or bowls used for cleansing seem to only come up in this forum. I have NEVER heard them from practitioners, in my shop, or even from telephone clients who seek my help through rootwork advice and consultations. I think the reason these things come up is that the internet attracts people who are new to root doctoring and conjure and have no experience with it at all, and tend to complicate and complexify it, often from a standpoint of making it more difficult and costly than it need be.
Let's look at the history: Hoodoo is African American folk magic and for hundreds of years, African Americns were slaves and then servants. Only recently have they taken their place as equals under law with white Americans. Due to these conditions, they were kept in poverty and want. You speak of an altar, but in a small house or apartment, 90% of conjure altars have traditionally been located on a nightstand or side-table or vanity or chifferobe or the top of a piano or refrigerator or mantelpiece.
Now let's ask the obvious question: Would the folk magic of a community that lived frugally, due to widespread economic discrimination and hardship, whose very altars were positioned on word-a-day and makeshift items of furniture include such conspicuous WASTE as throwing away a wash cloth every time it was used to wipe down a nightstand or side-table or vanity or chifferobe or the top of the piano or refrigerator or mantelpiece>
The answer is obviously, "No."
Furthermore, for the record, in the days before the invention of plastic varnish, if the furniture was varnished in the conventional way, the use of a caustic alcoholic substance like Florida Water would be damaging to the furniture finish. Most altar spaces are covered with a nice cloth, anyway, and those cloths would have been hand-edged in lace. Would you throw away your hand-made laced cloth every time you wanted to clean your altar.
Hoyt's Cologne, 2 oz.
Oh, and last of all, Florida Water was never used in hoodoo until the heavy immigration of Afro-Caribbean practitioners of Santeria got in on the scene. Hoyt's Cologne was our cologne of choice -- and it was NEVER used for washing altars. You would wash the altar cloth by hand in Fels Naptha or Ivory Flakes and wash the altar with Chinese Wash.
And that's the way i still do it, and the only way i recommend that my students work.
