Hi @christy6,
You’ve already got some great cleansing suggestions from the coven - adding another vote for the sprays and sound/music. Those are great ways to clean and as a bonus, they don’t require any cleaning up!
For cleansing a large space, sprays and sound are great methods that don’t involve smoke. For cleansing tools and small items, my current favorite cleanser is salt 
Using sea salt taps into Ocean Magick and the immense power of the sea. It helps to wash away negativity or things you need to let go of, and bring in a wave of abundance and vitality.
Salt is a general cleanser, but it is also incorporated into specific cleansing spells - such as hex/curse removal, banishing illness, and removing stress from the mind and the body.
I hope you can find some cleansing methods that work well for you, Christy - good luck and blessed be!
