Simple Green Dilution Ratio Chart

Simple Green is one of those cleaners that looks simple on the shelf, then gets confusing once you start mixing it. The bottle is concentrated, which is great for saving money, but it also means you need to know how much water to add. Too weak, and grease laughs at you. Too strong, and you waste cleaner or leave extra residue behind.

The easy starting point is this: use 1 part Simple Green to 10 parts water for heavy cleaning, 1 part Simple Green to 30 parts water for general cleaning, 1 part Simple Green to 50 parts water for light cleaning and floors, and 1 part Simple Green to 150 parts water for glass, mirrors, and very light wiping. Full strength is best saved for tough grease, concrete stains, grills, tools, and other stubborn jobs that can be rinsed well.

High-End Cleaning Setup Picks

A good dilution setup makes Simple Green easier to use and harder to waste. For a premium cleaning station, look at Simple Green All-Purpose Cleaner gallon jugs on Amazon, Simple Green Industrial Cleaner & Degreaser 5-gallon pails, chemical-resistant 32 oz spray bottles, commercial janitorial carts, wall-mounted chemical dilution dispensers, and shop floor scrubber machines. A full garage, shop, or small business cleaning setup with pails, bottles, dispensers, scrubbers, microfiber, protective gloves, floor machines, and storage can pass $2,000 fast.

You do not need a commercial closet to mix Simple Green well. A measuring cup, a labeled spray bottle, and clean water can do most jobs. Think of the concentrate like coffee syrup. A little can flavor the whole cup. Too much turns the drink into a sticky mess.

Simple Green Dilution Ratio Chart

The ratios below use the common cleaning meaning of dilution: Simple Green to water. A 1:10 mix means 1 part Simple Green and 10 parts water. If you use 1 ounce of Simple Green, add 10 ounces of water. The finished mix will be 11 ounces total.

Cleaning Strength Simple Green Ratio Best For Easy Mix
Full strength No water added Heavy grease, grills, tools, concrete spots, engines Use straight from bottle, then rinse well
Heavy cleaning 1:10 Greasy counters, trash cans, tires, workbenches, outdoor grime 1 oz Simple Green + 10 oz water
Medium cleaning 1:30 General spray cleaner, appliances, walls, baseboards, car interiors 1 oz Simple Green + 30 oz water
Light cleaning 1:50 Floors, light dust, mild dirt, routine wiping 1 oz Simple Green + 50 oz water
Very light cleaning 1:150 Glass, mirrors, light fingerprints, display cases 1 teaspoon Simple Green + about 16 oz water

Simple Green Mixing Chart for Spray Bottles

Most home cleaning happens with a spray bottle. The chart below gives easy amounts for 16 oz, 24 oz, and 32 oz bottles. Exact perfection is not needed for basic household cleaning, but close measuring helps you get the same result each time.

Bottle Size 1:10 Heavy 1:30 General 1:50 Light 1:150 Glass
16 oz bottle 1.5 oz Simple Green, fill with water 0.5 oz Simple Green, fill with water 2 tsp Simple Green, fill with water 1 tsp Simple Green, fill with water
24 oz bottle 2 oz Simple Green, fill with water 0.75 oz Simple Green, fill with water 1 tbsp Simple Green, fill with water 1.5 tsp Simple Green, fill with water
32 oz bottle 3 oz Simple Green, fill with water 1 oz Simple Green, fill with water 2 tbsp Simple Green, fill with water 2 tsp Simple Green, fill with water

For most homes, the 1:30 bottle is the workhorse. It handles counters, sinks, stove fronts, plastic furniture, baseboards, trash cans, and light garage mess. Keep a 1:10 bottle for greasy jobs and a 1:50 bottle for floors or light wiping.

What Does 1:10 Simple Green Mean?

A 1:10 Simple Green ratio means 1 part cleaner and 10 parts water. That could be 1 ounce cleaner and 10 ounces water, 1 cup cleaner and 10 cups water, or 100 ml cleaner and 1,000 ml water. The unit does not matter as long as both parts use the same unit.

This is a strong mix. Use it when soil is heavy, greasy, sticky, or old. It is useful for stove areas, garbage cans, patio furniture, greasy tools, tires, grills, and workshop surfaces. Spray it on, give it a short dwell time, scrub if needed, then rinse or wipe clean.

What Does 1:30 Simple Green Mean?

A 1:30 ratio means 1 part Simple Green and 30 parts water. This is a good general-purpose mix. It is strong enough for normal grime but not as heavy as the 1:10 mix.

For a 32 oz spray bottle, add about 1 oz of Simple Green, then fill the rest with water. This is one of the easiest bottles to keep under the sink because it works for many everyday jobs. It is the cleaning version of a comfortable pair of shoes.

What Does 1:50 Simple Green Mean?

A 1:50 mix means 1 part Simple Green and 50 parts water. This is a light cleaner. It works well when the surface is not very dirty or when you are cleaning a large area, like a floor.

For floor mopping, 1:50 is a smart place to start. Stronger mixes can leave more residue if the floor is not rinsed well. A light mix cleans routine dirt without making the floor feel tacky afterward.

What Does 1:150 Simple Green Mean?

A 1:150 mix is very light. It is often used for glass, mirrors, windows, and light fingerprints. For a 16 oz spray bottle, about 1 teaspoon of Simple Green is enough. Fill the rest with water.

Glass cleaning needs a light touch. Too much cleaner can streak, like too much soap left in a drinking glass. Use a small amount, wipe with a clean microfiber cloth, then buff dry.

Simple Green Dilution for Kitchens

For kitchen counters, stove fronts, sinks, cabinet fronts, and small appliances, start with 1:30. If the area is greasy, use 1:10. For ovens, grill grates, and heavy grease, full strength or 1:10 may be needed.

Food-contact surfaces should be rinsed with clean water after cleaning. Do not leave cleaner sitting on cutting boards, dishes, utensils, or counters where food will touch. Clean first, rinse next, then dry.

Simple Green Dilution for Bathrooms

For bathroom sinks, counters, tubs, showers, toilets, and trash cans, use 1:10 to 1:30. Use 1:30 for light soil and 1:10 for soap scum, body oils, and grime around tubs or shower doors. Let the cleaner sit briefly before scrubbing, but do not let it dry on the surface.

For mirrors, use 1:150. A stronger mix can leave streaks. Spray the cloth instead of soaking the mirror, then wipe in smooth passes.

Simple Green Dilution for Floors

For regular floor cleaning, start with 1:50. For a bucket, that means about 1 ounce of Simple Green in 50 ounces of water, or about 2.5 ounces in 1 gallon of water. For dirty garage or shop floors, use 1:10 to 1:30 depending on the soil.

Use less cleaner on shiny floors, sealed floors, or floors that streak easily. Rinse if needed. Too much cleaner can leave a film, and that film can pull dust back like a magnet.

Simple Green Dilution for Cars

For car interiors, vinyl, plastic trim, mats, and door panels, use 1:30 and test first. Spray the cloth, not electronics, screens, or controls. Wipe gently and dry with a clean towel.

For wheels, tires, and greasy areas, use full strength to 1:10. Rinse well. Avoid letting strong cleaner dry on paint, polished aluminum, or delicate finishes. Work in shade when possible because hot surfaces can dry cleaner too fast.

Simple Green Dilution for Concrete and Garage Floors

Concrete can handle stronger cleaning than many indoor surfaces. For oil spots, grease, and old grime, use full strength or 1:10. Wet the surface first, apply the cleaner, scrub, then rinse well.

For general garage floor cleaning, 1:30 may be enough. For routine mopping after the heavy dirt is gone, 1:50 can work. Concrete is tough, but residue still matters. Rinse well so the floor does not feel slick.

Simple Green Dilution for Tools and Parts

For hand tools, toolboxes, and greasy shop surfaces, use 1:10 to full strength. For parts washing, some jobs may need a stronger mix, often around 1:2 to 1:5 depending on the soil and the cleaning method. Always rinse and dry metal parts to reduce the chance of spotting or corrosion from trapped moisture.

Do not soak delicate metals without checking compatibility. Aluminum, bare metal, and specialty coatings deserve extra care. Test a small spot first, and do not let strong cleaner sit longer than needed.

Simple Green Dilution for Glass and Mirrors

For glass, mirrors, windows, and display cases, use 1:150. In a 16 oz spray bottle, that is about 1 teaspoon of Simple Green topped off with water. For a 32 oz bottle, use about 2 teaspoons.

Use a clean microfiber cloth or lint-free towel. If you see streaks, the mix is probably too strong, the cloth may be dirty, or the glass may need a dry buff after wiping.

Simple Green Dilution for Laundry

For laundry stains, a 1:30 pre-treat mix is a good place to start. Spray the stained area, let it sit briefly, then wash. For heavy stains, use a stronger mix, but test fabric first. Do not use on fabrics that cannot be washed with water.

Some Simple Green guidance lists 1/4 cup for a full laundry load for certain products, but product type and machine type matter. Avoid adding concentrated cleaner to high-efficiency machines unless the product label allows it. When in doubt, pre-treat and rinse instead of pouring cleaner into the machine.

How to Mix Simple Green Correctly

Start with a clean bottle. Add water first, then Simple Green. This helps reduce foaming. Leave a little space at the top of the bottle so you can shake it gently. Add the sprayer, tighten it, and turn the bottle over a few times to mix.

Label the bottle with the ratio and date. Write “1:10 Heavy,” “1:30 General,” “1:50 Floors,” or “1:150 Glass.” A label keeps your cleaning shelf from becoming a guessing game.

Should You Use Hot or Cold Water?

Simple Green can be mixed with hot or cold water for many cleaning jobs. Warm water can help with grease because it softens oily soil. Cold water is fine for routine cleaning and spray bottles.

Do not use boiling water in plastic spray bottles. Heat can soften plastic, build pressure, or make the bottle warp. Warm tap water is enough for greasy kitchen or garage jobs.

Do You Need to Rinse Simple Green?

Rinsing is a good habit, especially on food-contact surfaces, floors, metal parts, glass, and any surface cleaned with a strong mix. A light wipe may be enough for some general cleaning, but stronger mixes should not be left behind.

Rinse when the surface will touch food, bare skin, pets, children, or heat. Rinse when the surface feels slippery, sticky, or dull after cleaning. Rinse when you are not sure. Clean water is the reset button.

Surfaces to Test First

Always test a hidden spot before using Simple Green on painted surfaces, polished metals, plastics, fabrics, upholstery, stone, sealed wood, laminate, rubber, and older finishes. A cleaner can be safe for many washable surfaces and still disagree with one coating, dye, or finish.

Do not use Simple Green on leather or non-washable surfaces. Avoid soaking wood. Avoid spraying electronics directly. For screens, keyboards, and controls, spray the cloth lightly, then wipe.

Full Strength vs Diluted Simple Green

Full strength is tempting because it feels like the fastest route. Sometimes it is. Heavy grease, concrete oil spots, grills, tools, and old grime may need it. But full strength is not the answer for every mess.

Diluted cleaner often works better for everyday surfaces because it spreads well, rinses more easily, and costs less per use. A concentrate is like a loaf of bread. You do not eat the whole loaf for one sandwich.

How Much Simple Green per Gallon of Water?

For a 1:10 heavy mix, add about 12 to 13 ounces of Simple Green to 1 gallon of water. For a 1:30 general mix, add about 4 ounces of Simple Green to 1 gallon of water. For a 1:50 light mix, add about 2.5 ounces of Simple Green to 1 gallon of water. For a 1:150 very light mix, add about 0.85 ounce, or roughly 5 teaspoons, to 1 gallon of water.

For mopping, the 1:50 mix is usually a better start than a strong bucket. If the floor is very dirty, clean once with a stronger mix, rinse, then maintain with a lighter mix.

Simple Green Ratio Mistakes

One common mistake is mixing every bottle full strength. This wastes cleaner and can leave residue. Another mistake is using the same bottle for glass, grease, and floors. Glass needs a much weaker mix than greasy tools.

A third mistake is not labeling spray bottles. A clear bottle of cleaner can look like every other clear bottle. Labeling takes ten seconds and prevents the wrong mix from landing on the wrong surface.

Quick Simple Green Dilution Guide

Use full strength for heavy grease, grills, tools, oil spots, and tough concrete stains. Use 1:10 for greasy kitchens, trash cans, tires, workbenches, tubs, and outdoor grime. Use 1:30 for general cleaning, appliances, counters, walls, car interiors, patio furniture, and baseboards. Use 1:50 for light cleaning, routine floors, and mild dirt. Use 1:150 for glass, mirrors, display cases, and light fingerprints.

Start with the weakest mix that may work, then move stronger if needed. That saves cleaner, lowers residue, and makes rinsing easier. A good dilution should cut the mess without leaving its own mess behind.

Final Answer: Best Simple Green Dilution Ratio

The best Simple Green dilution ratio depends on the job. For heavy cleaning, use 1:10. For general cleaning, use 1:30. For light cleaning and floors, use 1:50. For glass and mirrors, use 1:150. Use full strength only for stubborn grease, concrete stains, tools, grills, and other hard jobs that can be rinsed well.

Mix with clean water, label each bottle, test hidden spots first, and rinse surfaces when needed. With the right ratio, one bottle of concentrate can stretch a long way, like a small key opening a whole row of doors.
