I should first start off by saying I am diagnosed with OCD and I have a terrible fear of chemicals and the damage they can cause on the human brain/body.

Yesterday as I was returning from the bathroom I caught my 4 year old spraying raid on the terrace.
Instantly I took it away from him washed his hands but I worry he sprayed it inside the apartment (as I only saw him when I was coming back) 
It’s a lavender/ no chemical order spray so I had a really hard time telling if it was sprayed anywhere else.. 

I may just be overthinking but I haven’t been able to sleep and I keep washing his toys alongside everything else on the terrace &amp; What I can’t wash I’ve been wiping repeatedly out of fear. This can claims to have residual effects for up 4 WEEKS and I don’t want my child anywhere near where it was sprayed but that’s usually where he plays. How can I try to relax myself feeling like the house is contaminated with a neurotoxic nerve agent that I don’t even know where exactly has been sprayed.. 

any tips or advice would be greatly appreciated. Apologies if I sound overly paranoid but I haven’t been able to get any sleep.
