If you need to disinfect your equipment between users, like loaner equipment. Here are some ideas.
Synthetic WasterThe grip area is of concern. I'd use a non-alcohol cleaner. Alcohol ones may break down the glue on the grip. For extra protection, I'd probably put some coats of polyurethane over the grip. Just goop it on and let dry. Then you can be more aggressive cleaning it. About 20 minutes in the sun will kill COVID. Do both sides. Just don't leave it in hot sun over an hour, it will start to flex more and be prone to warping.
Wooden Waster
I think any alcohol disinfectant would eventually dry out the wood. I don't know how long, like maybe a year, maybe 10 years. So it may not be a big deal for a quick wipe. The non-alcohol ones, if its a wipe-on-wipe-off quickly, should be fine. But wood doesn't like moisture at all. What I probably would do, is put a 2-3 coats of polyurethane on the grip guard and pommel. Not so much the blade, it will just get chipped off. That will give you a plastic/glossy smooth finish to work with. then you can probably use any cleaner on that, and it would be easy. About 20 minutes in the sun will kill COVID as well. Do both sides. Just don't leave it in hot sun over a couple hours, the wood will dry out and start to warp.
Steel Swords
Anything will be fine. Don't let liquids sit on the steel or it would rust. I'd oil afterwards. Again, the grip is at issue. If its cord wrapped, see the synthetic above. If its leather. Stick with the non-alcohol cleaners, spray on wipe off.

Clothing and masks.
Hopefully everyone has their own by now, but a good spray of disinfectant. Leaving in the sun for 20+ minutes will kill COVID as well. But getting all the hidden spots in fabric products will be more difficult. Check if alcohol cleaners will bleach the fabric. Wash clothing according to instructions
