Mix the right shampoo strength for carpet cleaning outdoors. Choose soil presets or ratios quickly. Save batches, costs, and notes for future cleaning days.
| Scenario | Area | Coverage | Tank | Soil | Planned batches | Concentrate per batch |
|---|---|---|---|---|---|---|
| Garden entry mat refresh | 120 sq ft | 220 sq ft/gal | 1 gal | Light | 1 | 1.00 fl oz |
| Patio carpet seasonal clean | 400 sq ft | 200 sq ft/gal | 2 gal | Normal | 2 | 3.50 fl oz |
| Greenhouse runner deep scrub | 650 sq ft | 170 sq ft/gal | 3 gal | Heavy | 2 | 7.50 fl oz |
Outdoor carpet runners, patio mats, and greenhouse walkways trap grit, pollen, and algae film. This calculator turns area and coverage inputs into a target solution volume, so you can plan refills and avoid mixing too little. Enter realistic coverage from a small test strip, then scale up. The batch output aligns your sprayer, extractor, or bucket to the same working concentration each refill.
Coverage rate links your tool and technique to solution demand. A higher rate means lighter application and faster drying, useful for routine garden-mat refreshes. A lower rate increases dwell time and agitation efficiency, better for seasonal deep cleans or shaded patios. Because coverage varies with pile height and soil load, the calculator lets you adjust the rate and immediately see how many tanks the job requires.
Soil presets provide practical starting ratios for concentrate strength. Light targets dusty surfaces and quick rinses, Normal supports traffic lanes and mild oils, and Heavy addresses stubborn stains near potting benches. If your label specifies a different dilution, switch to custom ratio and enter it directly. The per-batch concentrate and water outputs help you measure accurately without mental conversions.
Waste allowance adds controlled overage for priming hoses, foaming loss, and leftover liquid in the tank. A default 5% suits most small sprayers; windy outdoor work or long lines may justify 8–12%. The calculator rounds batches up to full tanks, which simplifies workflow: mix, apply, refill. Consistent batch sizing reduces performance swings and helps you compare results across different cleaning sessions.
Cost tracking moves decisions beyond bottle price. Enter concentrate cost per volume unit to estimate total concentrate spend for the planned batches. This supports budgeting for large patio carpets, comparing premium low-foam formulas versus economy blends, and forecasting seasonal maintenance. Use exports to log your inputs and outputs, then refine coverage and ratio after each job to improve accuracy and reduce waste over time. Tracking those changes creates a repeatable process and protects outdoor fibers from over-strong mixes. Year after year.
Measure a small test area and note how much solution you used. Divide tested area by used tank volume to get a realistic rate. Use that value for better batch and refill estimates.
No. Presets are practical starting points for outdoor mats and runners. If your shampoo label specifies a dilution, use the custom ratio option and follow the label as the primary reference.
Outdoor work is easiest with full, repeatable tanks. Rounding up prevents running short near the end of a job and keeps concentration consistent across refills, even if your final tank is not fully used.
Enter the percent of concentrate volume you plan to add as defoamer. The calculator estimates the per-batch and total defoamer amounts. Keep percentages low and compatible with your cleaning equipment.
Yes. Select Metric units to work in square meters, liters, and milliliters. Preset ratios automatically convert to ml/L, and the outputs update to match your measuring tools.
It estimates concentrate-only spend for the planned batches based on your entered unit cost. It does not include water, electricity, equipment wear, or labor, so treat it as a planning baseline.
