After a scene, another thing you’ll need to do is clean up. How exactly you do so is entirely dependent on what you’ve been doing, and what implements you have used. Since there’s an almost endless variety of situations and cleanups you might encounter, I won’t try to cover them all here, but will just share a few common practices.
First, make sure you wipe down any surfaces and any equipment used particularly if playing in a public space or dungeon. It’s only polite, and demonstrates a courtesy towards the next people to use whatever piece of equipment it is.
If something has gotten blood on it, make sure to clean it very thoroughly – with sterilising agent or at a high temperature if possible. Leave it to dry out for as long as you can – preferably several weeks – to ensure that there’s no possibility of transmitting blood borne diseases to the next person to use the toy or implement.
Dispose of anything with poses a risk of infection (fresh blood, bodily fluids, etc) in a safe and responsible manner. If clinical waste bins are available, dispose of it there. If not, bag it up and dispose of it as you normally would, after making sure that it’s thoroughly sealed.
Dispose of any used sharps in a sharps bin, or at the very least in a rigid container. A bleach bottle makes a good stand in for a real sharps bin, but if you plan to use sharps on a regular basis I’d thoroughly recommend investing in a bin.
If your play regularly involves bodily fluids and the spilling thereof, it’s a good idea to invest in equipment to clean up with – or else take precautionary measures, such as putting down a towel or tarpaulin to protect the area that you’re using. Most serious players I know have developed some kind of system for ensuring that they don’t make a terrible mess every time they open up the toy bag.
Finally, some items are only single use. It may be possible to rinse them off and use them again, but it is unwise to do so. If something is made to only be used once and then discarded, then that is what you should do. Speculums and TENS machine pads, for example, are designated single use for the very good reason that – even after a single usage – they can carry disease which can be passed onto the next user. If something is single use, bin it after using it.
