@fab01 What is your goal? Clean, sanitize, or disinfect? Because those are 3 very different things and need different approaches.
If you are looking to clean washing in soapy water and rinsing will do the trick. If you are wanting to sanitize or disinfect you need to boil, steam, or apply a chemical for a set period of time (about 2 minutes to sanitize and about 10 minutes to disinfect - depending on the product in question and its concentration, always read product label for detailed instructions)
My recommendation would be diluted bleach. But you'll have to follow the instructions to properly sanitize or disinfect if that's the goal. It dissolves into salt and water (which evaporates) making it safe for use. A few problems: it may discolour toys, it can leave behind a white powder (salt residue). Bleach is also rendered inactive by organic material (visibly dirty objects) so in cases where you wish to sanitize or disinfect the first step would be to clean and remove any visible debris.

quick spraying the toys down with whatever you ultimately end up choosing isn't likely to achieve any of these goals: you won't scrub enough to clean and contact time won't likely be long enough to sanitize or disinfect. You can always test how long the product stays wet to determine if it achieves the proper contact time based on the amount you sprayed.
Basically when it comes to cleaning (but especially sanitizing or disinfecting) one needs to do it the right way.
