I like a clean car. My head is clearer to do things when I clean the car. I won’t wash my car on chol hamoed, but I just want to clean dirt off the windows and car exterior/interior with a rag and some window liquid cleaner. May it be done by me?
Thank you for your question.
Although it may not be in the spitir of Yom Tov, technically there is no prohibition against washing a car on Chol Hamoed.
