you could look into potion craft. a potion is basically any spell that involves liquid. it could be a tea, bath, oil, or brew. very basic is make solar and lunar waters. solar water you place a bowl of water in the sun for a day. lunar you place a bowl of water under the moon for one whole month [keeping it out of the sun]
i think the simplest to start with would be baths. make a milk bath, i have a spell posted for each season milk baths. for the tea's you should look into herbalism a bit. brews are simple also, a basic cleansing brew for washing floors/surfaces is lemon juice, rosemary and sea salt in warm water. stir it and say a protection chant.
the hardest is oils, possibly flavoured waters like rosewater because it involves finding/making an evaporation tank. it's very easy to burn the herbs so you end up infusing your oil with smoke [so to speak] so you should look into that last and just buy essential oils, or non artificial flavouring.
