Supply & Chemical Inventory: the full procedure
Count, reorder, and rotate chemicals and consumables so the site never runs out and stock is stored safely.
- Applies to: Shift leads, inventory lead, owner
- Frequency: Weekly count; reorder at par
- Scope: Covers counting, reordering, and rotating wash chemicals and consumables. Chemical storage, handling, and disposal DEFER to the product SDS and OSHA Hazard Communication; this SOP owns the counting, par-level, and reorder process.
What you need
- Inventory count sheet with par levels
- SDS binder
- Vendor/order contacts
- Labeled storage shelving with containment
- Towel/consumable stock area
- Reorder log
The procedure, step by step
- Count to the same sheet every time — Walk the storage area and count chemicals and consumables (towels, applicators, tire dressing, etc.) on the standard count sheet on the set day.
- Compare each item to its par level — Flag anything at or below par for reorder so the site never runs dry mid-shift.
- Place orders against par, not guesswork — Order to bring each item back to par with the approved vendor; record the order in the reorder log.
- Receive and verify deliveries — Check incoming stock against the order, confirm intact containers and intact labels, and reject damaged or unlabeled chemical containers.
- Rotate stock first-in-first-out — Shelve new stock behind existing so older product is used first; check any dated product for shelf life.
- Store safely per SDS — Place chemicals on containment shelving with compatible classes separated and labels facing out, per the SDS and Hazard Communication.
- Log usage trends for the owner — Note unusually fast or slow movers so the owner can adjust par levels and spot waste or over-dilution issues.

This is a free, source-anchored standard operating procedure (SOP) you can print and hand to staff. It documents the work sequence for a Car Wash business — not safety or regulatory rulings, which defer to the cited authorities, the applicable code, and your own health-and-safety plan.

Frequently asked questions
How do par levels prevent running out of supplies?
A par level is the minimum quantity that triggers a reorder, set per item by the owner. Counting on a fixed schedule and reordering anything at or below par keeps the site from running dry mid-shift. Recording each order in a reorder log makes usage trends visible so par levels can be tuned.
How should incoming chemical stock be stored?
Verify deliveries against the order, reject damaged or unlabeled containers, rotate stock first-in-first-out, and shelve on containment with incompatible classes separated and labels facing out. All storage, separation, and disposal rules defer to the product SDS and OSHA Hazard Communication — the SOP standardizes the counting and reorder process around them.
