ICS Promo Codes & Coupons February 2026

At ICS car washes, enter your 4-digit PLU code on the payment terminal's numeric keypad after selecting your wash package but before final payment.

1. Drive up and select your wash via the kiosk
2. At the payment terminal, choose your wash package
3. Press the "PLU/Discount" button (often labeled as such or under "Extras")
4. Input your 4-digit code on the numeric keypad
5. Hit enter to apply the discount
6. Confirm the discount shows before completing payment

Note that PLU codes typically only apply to base services, not add-ons like wax upgrades. If you see "Invalid PLU" flashing, your code may have expired or your vehicle height might exceed limits (e.g., over 7ft for certain promo washes).

Most ICS discount codes are valid Monday-Friday 9AM-5PM, one per vehicle, and cannot be stacked with app deals. Many codes don't work during peak hours after 6PM.

Pro tip: Test PLU codes mid-morning on weekdays when systems sync fresh promo data from ICS's central server for highest success.

ICS PLU discount coupons at Auto Sentry kiosks apply only to the base wash package, not extra services like tire shine or undercarriage clean. This is due to ICS policy that limits promotions to core wash items only.

You may see "Discount Applied to Base Only" or no price change on extras because ICS separates base washes from upsells in their pricing structure. This is especially common during busy hours when kiosks may not properly cache data.

If you're experiencing this issue:

1. Enter your PLU after selecting the base wash
2. Either skip extras or pay for them separately
3. If there's a system glitch, ask an attendant to restart the kiosk

Remember that extras will always ring at full price, codes typically expire at month-end or after 1000 uses site-wide, and you cannot combine PLU codes with loyalty points.

Pro tip: Consider bundling extras into a single "Ultimate" package first—many PLU codes cover the whole tier, saving you the hassle of re-entering information.

"No Discount Applied" or a blank discount field on the ICS Touch POS means your code is expired, ineligible for your selected items, or was entered incorrectly. This commonly happens when PLU/coupon codes don't match the terminal's active promotion list.

This issue often occurs during checkout when POS synchronization fails, especially after midnight system resets. ICS policies prevent discount stacking or applying codes to already-discounted items.

To resolve this issue:

1. Double-check your code for case-sensitive entry
2. Verify your order meets minimum requirements (similar to the $100 minimum for bulk discounts)
3. Void the transaction and re-scan all items
4. Call an attendant for a manual override if "Promo Inactive" appears

Note that most ICS codes are only active during business hours (Monday-Saturday 8AM-8PM), and vehicle type or height restrictions may invalidate certain promotions.

Pro tip: Screenshot your code's source (email/app) before arriving; attendants can verify and process your discount faster when you have proof.

Call your local ICS car wash or check their app/website promotion page to verify code validity. Most ICS locations list dates, times, and vehicle height restrictions explicitly for their promotions.

Since there's no central verification tool for PLU codes, you'll need to:

1. Visit the ICS site or app and search for "promotions" or "promos"
2. Carefully read the fine print (e.g., "Valid M-F 10AM-4PM, sedans only")
3. Text the code to the ICS service number or call your local store directly
4. If uncertain, test the code at an off-peak time when kiosks are available

Be aware that many ICS promotions time out after 100 uses or at the end of the month. Height restrictions are automatically enforced by sensors that will reject taller vehicles even if you have a valid code.

Pro tip: Measure your vehicle height at home and try to arrive about 30 minutes before the promotion window ends to avoid cutoff synchronization delays.

ICS may occasionally offer discount codes, but currently, there are none available. However, customers can still save money by taking advantage of other promotional offers or sales available on the website, or by using credit card points to make purchases.

We couldn't find any available data on how often ICS releases new discount codes. Based on historical data, the average time between ICS coupon releases is approximately 30+ days.
