Sow Kheng

I have had OCD since my childhood over 50 years. I wipe all sorts of things Shopping Items mostly things that come from outside the house I have a real problem when anything I drop or my husband drops on the floor/ground. It could be a set of keys or anything he has handled after picking anything something that has touched the floor/ground. I have clean it multiple times. I wipe with paper towels up to 20 times Does anyone else have this type of problem Any suggestions
