You can use your credit card on the soft touch and touch less, the was yourself is still coins or cash.
The car wash requires coins/quarters. They have a machine where you can buy them with cash/credit/debit card for no additional fee. You can either use quarters (8 quarters = 4 minutes) or their Liberty Car Wash tokens (2 tokens = 4 minutes and each token costs $1 unless you buy in bulk)
