I know some people say rubbing alcohol is fine to use, but it is quite harsh and I personally have experienced an unbalanced ph of my vagina by using this method, even when rinsing. Not everyone is the same, so you might be fine. I wouldn't recommend it personally and harsh cleaners like alcohol also have the potential to cause minor imperfections in toys. This link (awesome blog) will tell you that alcohol should be used sparingly Sex Toy Care and Maintenance
You can use vaginal wipes, there are anti bacterial brands, toy cleaning wipe and toy cleaner. Mild antibacterial soap and hot water as well. These should all be more than sufficient to clean your toys thoroughly. MILD soap is important! I actually use a PH balanced vaginal wash to be safe before I use my toys and an antibacterial soap and hot water after use. Obviously that may be a lot more work than you're looking for, but it's a suggestion and can be done in the shower.
The best part is, your toy is silicone, you only have to worry about surface bacteria. If you have washed it thoroughly with antibacterial soap and hot water, you really should be fine
I hope that is helpful!
