Degreaser Bath Life Calculator

How many parts a soak bath treats before recharge, how often that falls, and the chemical cost of one part.

Inputs

Range: 1–500 gal

Enter the measured quantity in the unit shown.

Range: 1–100

The share of the bath that can be lost to drag-out before the concentration falls below the working strength. Half is typical for a soak bath.

Range: 0.001–5 gal

Measure it: weigh a part dry, dip it, let it drain the usual time, weigh it again. A complex part with blind holes carries far more than a flat plate.

Range: 0–1,000,000 per gallon

Enter the current purchase price in US dollars for the unit shown.

Range: 1–10,000

Enter the measured or label value in the units shown.

Reading: what this result means for the job
A normal recharge interval. The bath life is a planning figure and an upper bound: soil loading also weakens the bath, so a bath that looks usable at the arithmetic interval may already be cleaning slowly.
Applicability limit
Bath life here is set by drag-out, which is measurable, and by nothing else. The model gives an upper bound on parts per bath: soil loading, oil carry-in and evaporation also change the bath, and none of them appear in the arithmetic. This is a planning figure for the values entered, not a measured result. Coverage rates, product yields and application rates are properties of a specific product, applicator and substrate, and the label or data sheet for the product you are using always takes precedence over the default here.

What to check

  • Measure drag-out on a representative part rather than assuming a film thickness.
  • Check the actual bath volume to the fill line, not the nominal tank size.
  • Confirm the recharge fraction against the concentration the work needs.

Bath life depends on drag-out, which is measurable: weigh a part dry, dip it, drain it as usual and weigh it again. A bath also loses strength to soil loading, so the drag-out model is an upper bound on parts per bath, not a guarantee.
