I use incense alot to cleanse, like sandlewood.
I also use it to cleanse my tarot deck too.
After awhile you don't want different energies of differest things phucking up your tarot deck and anything else, that can channel energy.

damn, and i never once cleansed my own tarot deck after giving my siblings and other relatives small readings

I think you'll be okay.
Did you know that you can actually piss of your Tarot deck?
At least that's what someone told me...
If the deck is inactive or not treated well, it won't let itself be used for the person who mistreated it.

I think that is why cleansing and management are so important.
