ShelfYears, the garage shelf-life reference

Field notes

ShelfYears compares sealed and opened storage windows rather than treating expiration as a single date. Its entries connect deterioration to a practical consequence, such as equipment damage from old gasoline or a safety issue from degraded brake fluid. The homepage divides the subject into six racks containing 69 listed products in total, including fuels, automotive fluids, cleaning chemicals, paints and adhesives, shop consumables, and yard, pool and pest chemicals. It also points readers toward label-date and SDS-reading explainers.
