Purple Power Dilution Calculator

Purple Power dilution from heavy to light

Purple Power's published guidance runs on a scale of strength. Full strength is for heavy grease, engines and industrial equipment. 1:1 is for heavy general degreasing, shop floors and tools. 1:3 is for everyday cleaning, painted surfaces and marine use, and 1:4 or weaker is for light-duty household surfaces. Purple Power's page does not spell out what the ratios mean, so this calculator reads them as parts of Purple Power to parts of water, and your bottle wins if it says otherwise.

Because the label bands are wide, the practical rule is to start weak and go stronger only if the soil holds on. A weaker mix is cheaper, easier to rinse, and gentler on paint and plastics. Most household jobs sit at 1:3 or 1:4.

Aluminum and clear coat are the two big cautions. Purple Power's website lists aluminum among the surfaces it works on and says to test a small, inconspicuous area first, but its safety data sheet lists polished aluminum under 'do not use on' and notes mild reactivity to aluminum (the pH is 11 to 13). Retailer label text also warns that full strength can leave white streaks or a hazy film on aluminum and stainless steel. Avoid full strength on clear-coat automotive finishes and use 1:3 or 1:4 there, rinsing thoroughly. Keep contact short and do not let it dry on the metal.

It is a heavy degreaser, so wear gloves and eye protection, rinse the area well, and follow local rules for disposing of used solution. Keep it away from unsealed wood and food-contact surfaces you will not rinse.

Never mix Purple Power with bleach, ammonia, acids or other cleaners. Mixing can release harmful gases. If it already happened, get to fresh air, open windows, and call Poison Help at 1-800-222-1222 (US); call 911 for trouble breathing, chest pain or collapse. Formulas change by version, so confirm on your bottle before you mix.

Spray bottles are the most common use, and a 24 oz bottle at 1:3 needs 6 ounces of Purple Power and 18 of water. Add the water first, then the concentrate, and label the bottle. Do not reuse an old food or drink bottle, and keep the mix away from children and pets.

Where these numbers come from

The formulas and default values in this calculator are based on:

• Purple Power Industrial Strength Cleaner/Degreaser product page and dilution guide (purplepowerinc.com)
• Purple Power Industrial Strength Cleaner/Degreaser Safety Data Sheet
• America's Poison Centers. Note: the page does not define what 1:3 means and some label versions use a different scale, so confirm on your bottle's label

This is general household-cleaning guidance and planning math, not medical or professional advice. Product formulas change, so the label on your bottle always wins: follow its directions and warnings, test a hidden spot first, and never mix cleaning products. For a poisoning emergency call Poison Help at 1-800-222-1222 (US), or 911 if someone has trouble breathing.
