Safe to use white vinegar to disinfect...

[Tilia]

...my baby's hard plastic toys such as little people and balls? Even though she puts everything in her mouth?? Should I dillute to half water?

Hard plastic or hard toys are fine with straight white vinegar, no need to dilute. If something has puff paint or some sort of fabric with a special finish on it, don't use it. Around the house, don't use vinegar at all on marble, some special stones. Use diluted or no vinegar at all for tile grouting.

If you can, leave the vinegar on it for a little bit and then rinse it off with water.
