Delta Sonic Chicago Charge: How to Cancel and Dispute the Fee

A Delta Sonic Chicago charge on your card statement is a recurring monthly fee from Delta Sonic Car Wash for an unlimited wash membership tied to one of its Illinois locations. The company bills these plans automatically on the first of every month, and the charges continue until the member cancels. If you didn’t realize you signed up for an ongoing membership, or thought a promotion would end on its own, the charge is almost certainly an auto-renewing unlimited plan.¹

Each plan is tied to a single vehicle through a barcode sticker placed on the rear driver-side window at signup, and it allows one wash per day at any Delta Sonic location. The first month is prorated; after that, the full monthly rate hits your card on the first.¹ Delta Sonic also reserves the right to raise membership fees, with notice stated to be provided on receipts before the new charge processes.²

How to Cancel the Membership

Monthly plan holders can cancel at any time after the first full month’s charge has been processed. You have three options:

Online through the Unlimited Member Portal on Delta Sonic’s website, or the dedicated cancellation form.
By phone at 1-800-843-5477 (1-800-THE-KISS).
In person with a cashier at any Delta Sonic location.

Have the “Unlimited number” from your windshield sticker or the original receipt ready. Cancellations take 24 to 48 hours to process.¹

What You’ll Pay Before Cancellation Takes Effect

Delta Sonic issues no refunds or credits when you cancel a monthly plan. The membership stays active through the end of the month already paid for, and then stops.¹

Annual plans are different. If you paid for a full year up front, Delta Sonic’s policy is that the plan cannot be canceled before the one-year term expires and is non-refundable.³

If You Can’t Resolve the Charge With Delta Sonic

Some customers have reported difficulty getting cancellations processed. One complaint filed with the Better Business Bureau described a 45-minute phone call to secure a cancellation and refund after a location was closed for equipment failure. Another customer reported being charged $19.99 per month for more than two years after a single visit, only noticing when reviewing old statements; Delta Sonic responded that the customer’s card had been physically present at enrollment.⁴

If the company won’t resolve the charge, federal law gives you a path through your card issuer. Under the Fair Credit Billing Act, you can send a written dispute to your credit card company within 60 days of the first statement that showed the error. Send it to the billing inquiries address (not the payment address), with your name, account number, and a description of the charge. The issuer must acknowledge the dispute within 30 days and resolve it within 90 days.⁵

While the dispute is open, you can withhold payment on the disputed amount. The issuer cannot close your account or report you delinquent on the disputed charges during that period. Federal law also caps liability for unauthorized credit card charges at $50.⁵

Illinois Auto-Renewal Law and the Pending Class Action

Because your charge comes from an Illinois location, state law may be relevant. The Illinois Automatic Contract Renewal Act (815 ILCS 601) requires sellers of auto-renewing subscriptions to clearly disclose, before the contract is fulfilled, that the agreement continues until the consumer cancels, the deadline to cancel before the next charge, the recurring amount and any potential price changes, and the length of each renewal term. The seller must obtain affirmative consent before charging the payment method and must provide a retainable acknowledgment that includes the cancellation policy and instructions. Customers who sign up online must be given a way to cancel entirely online.⁶

A violation is treated as an unlawful practice under the Illinois Consumer Fraud and Deceptive Business Practices Act. The law includes a safe harbor: a company can avoid liability if it has written compliance procedures, the violation resulted from an error, and it provides a full refund or credit from the renewal date through the termination date.⁷

In early 2026, a customer named Marianne Stacey filed a class action in Will County, Illinois, on behalf of a proposed class of more than 40 people who bought memberships at any of Delta Sonic’s 10 Illinois locations. The suit, brought by attorney Matthew T. Peterson, accuses Delta Sonic of violating both statutes above. Stacey, a Joliet customer, alleged that Delta Sonic failed to provide the required acknowledgments of renewal terms, cancellation policy, and cancellation instructions, and that when she tried to cancel through an attendant she was redirected to corporate and continued to be charged. The complaint seeks a declaration that the practices violate Illinois law, refunds for unauthorized recurring charges, and attorney’s fees. As of April 2026, a summons had been issued but Delta Sonic had not entered an appearance or filed a response.⁸
