PolyJohn Hot Flakes De-Icer, CK01-0120

When winter temperatures drop below freezing, untreated waste in portable restroom holding tanks can freeze solid — making units difficult or impossible to service until they thaw. The PolyJohn PRO's Choice Hot Flakes De-Icer (CK01-0120) is a pellet-based de-icer that, when added per the manufacturer's usage chart, prevents holding tank contents from freezing down to -25°F (-31°C). It is supplied in a 30-pound pail and is dosed by pounds per gallon of water based on the lowest expected temperature, with a 5-gallon net charge as the chart's reference baseline.

Hot Flakes Usage Chart

Dosing is based on the lowest expected ambient temperature. The chart below is per the manufacturer and is calculated for a 5-gallon net charge in the holding tank.

• 30°F: 0.25 pounds per gallon (ppg)
• 20°F: 1.35 ppg
• 10°F: 2 ppg

Key Features

Freeze Protection Down to -25°F
The PRO's Choice Hot Flakes formula is rated by PolyJohn to keep portable restroom holding tank contents from freezing down to -25°F (-31°C) when dosed per the usage chart. This makes it useful for winter portable restroom service in cold-weather regions where overnight lows can drop well below 0°F.

Pellet Form for Easy Dosing
Hot Flakes is supplied as pellets in a 30-pound pail. Operators scoop the chart-specified amount and add it directly to the holding tank — no measuring liquids, no mixing, no separate dispensing equipment. Dosing is straightforward to standardize across a winter route.

Temperature-Based Usage Chart
PolyJohn publishes a six-step usage chart (30°F down to -20°F) that ties dose rate to the lowest expected temperature, with 5 gallons as the reference net charge. This makes it possible to dial dose rates up or down by route, region, or forecasted overnight low rather than over-treating every unit.

Designed for Portable Restroom Service Operations
Hot Flakes is sold by PolyJohn as part of their portable restroom service consumables line and is intended for use in portable restroom holding tanks during winter service. It is not a roadway de-icer or a general antifreeze — it is formulated for tank-content freeze prevention so units stay serviceable and pumpable in freezing weather.

Application Guidance

Add Hot Flakes to the holding tank according to PolyJohn's usage chart and the amount of water in the tank. To calculate the dose, take the lowest expected temperature for the service interval, find the matching pounds-per-gallon (ppg) rate on the usage chart, and multiply by the gallons of water in the tank. The published chart values assume a 5-gallon net charge, so a tank with a different water volume should be dosed proportionally. Always treat to the coldest expected temperature between service visits, not the average — a single sub-rated overnight low can freeze a tank that was dosed for milder conditions.

Frequently Asked Questions

How cold can Hot Flakes De-Icer protect down to?
PolyJohn rates PRO's Choice Hot Flakes to prevent holding tank contents from freezing down to -25°F (-31°C) when dosed per the published usage chart. The chart's coldest line is -20°F at 3.3 pounds per gallon, with -25°F representing the lowest effective temperature stated by the manufacturer.

How much Hot Flakes do I add per unit?
Dose is set by the lowest expected temperature and the unit's net charge in gallons. The PolyJohn chart starts at 0.25 ppg for 30°F and scales to 3.3 ppg for -20°F, calculated against a 5-gallon net charge. Multiply the chart's ppg value by your actual charge volume to get the per-unit pellet weight.

What size container does Hot Flakes ship in?
The CK01-0120 ships as a 30-pound pail of pellets. Listed shipping weight is 35.0 lb, which accounts for the pail and packaging in addition to the 30 pounds of product.

How do I apply Hot Flakes to a portable restroom tank?
PolyJohn instructs operators to add the appropriate amount per gallon of water in the holding tank, using the published usage chart. The chart's pounds-per-gallon value at the lowest expected temperature is multiplied by the gallons of water in the tank to determine the per-unit pellet weight. Standard practice is to dose during winter service when the tank is recharged with fresh water and deodorizer.

Can I use Hot Flakes in any portable restroom?
Hot Flakes is a PolyJohn-branded consumable in their portable restroom service line and is intended for portable restroom holding tanks. It is not a sidewalk or driveway de-icer and is not formulated for vehicle radiators, plumbing lines, or potable water systems — it is a tank-content freeze inhibitor for service operators.

What is the lead time on the CK01-0120?
The CK01-0120 typically ships in 25 business days. For winter routes, order ahead of the first hard freeze of the season to avoid running short during the period when demand peaks across the industry.

Why does the chart say 5 gallons — what if my unit uses a different charge volume?
The PolyJohn usage chart is calculated on a 5-gallon net charge as the reference baseline. If your service charge is more or less than 5 gallons, scale the dose proportionally — for example, a 10-gallon charge at -10°F (3 ppg) would call for roughly twice the per-unit pellet weight of the 5-gallon chart figure.
