This is a general purpose bath. You need:
A handful of any of the following:
- Bay Leaves
- Eucalyptus Leaves
- Pine Needles
- (Or check with your tradition to find traditional cleansing ingredients)
And a washcloth.
Consider wrapping your ingredients in a coffee filter (I saw that tip on Tumblr!) so you don’t have to pick little bits of herbs out of the tub for an hour.
Draw a hot bath. Dusk or dawn is an opportune time, but do it whenever you have time for yourself. Put the salt and vinegar in first. Stir the bath a bit to let them dissolve and ask them to strip away all evils, bad energies, and unwanted spirits connected to you.
Put the herbs in second. Continue stirring the bath (even if the herbs are not loose) and ask the plants individually to add their powers (rosemary for protection, garlic to banish spirits, etc).
Get in the tub when it is cool enough. Again ask the powers present to fully cleanse you of what ails you; state specifically that you wish to be totally purified. Call upon the powers of your gods if you have any. Wash yourself vigorously from head to toe - specifically start at the top of your head and wash down to your feet. Rub your scalp, and every part of your body you can reach, including the soles of your feet.
As you do so, imagine the generous powers you have evoked washing away every negative thing attached to you. The cloud of steam and water around you dissolves negativity and refills your aura with pure and powerful vibrations.
Soak in the bath for as long as you desire. If you are religious, read prayers or parts of your holy book. This is a good time to state positive affirmations as well. When you are ready, get out and allow yourself to air dry (putting your hair in a towel is fine). If you are sticky, remain sticky for as long as possible before going back for a quick rinse.
Now that you are cleansed, immediately shield or put on protective amulets.
