How would you apply ERP to this OCD situation?

[canigetawitness]

Went to get cloth to clean fingerprints off TV.

Before wetting cloth, my mind said "You need to pump soap on that cloth and rub it on your TV screen for a theraputic exposure."

I thought, "That's a weird thought. I'll just use water. Soap isn't meant to be rubbed on TV screens."

Then, after wiping fingerprints off TV my mind says "Did I actually pump soap onto that cloth and rub it on the screen? I can't remember."

Now, what do I do? Do I need to rub soap on my TV for therapy or leave it alone? If there's soap on my TV, shouldn't I get a cloth to remove it? Do I need to rub soap on my TV for therapy or leave it alone? If there's soap on my TV, shouldn't I get a cloth to remove it?

This is the OCD cycle I'm caught in and I'm not sure how to break it. Also, I wouldn't even know how to describe this "theme" really.

Thanks in advance for any help/advice.
