Cleaning Mats and Shared Gear at Gyms and Studios

Cleaning mats and shared gear at gyms and studios is a surface routine you can run between classes and again at close of day: take off visible soil, then apply a tested batch of HOCl you make on site. This page is for yoga and pilates studios, martial-arts schools, and small gyms that wipe mats, blocks, bells, and other shared items. It is a handling and volume-planning guide.

The machine this site walks through is the Eco One, which makes a 1 L batch. HOCL LLC sells machines only; it does not sell bottled HOCl. If you do not yet have a making routine, start with How to Make Hypochlorous Acid at Home.

What you are cleaning

Mats. Yoga mats, grappling mats, and flooring tiles that people stand or lie on. These pick up sweat, dust, chalk, and tracked-in dirt. A dry sweep or a detergent wipe comes first; HOCl goes on the cleared surface.

Shared gear. Blocks, straps, rings, dumbbells, kettlebells, jump ropes, mitts, and similar hard or wipeable items that pass from person to person. Check that the material can take a water-based spray. Do not soak electronics, and do not use this routine on anything the manufacturer says to keep dry. Wipe metal gear dry afterward.

Other shared hard surfaces. Door handles, light switches, railings, the front-desk counter, and fountain or bottle-fill buttons. On switches and buttons, spray onto a cloth, not directly onto the fixture.

This page does not cover skin, feet, or any product applied to a person. This routine stays on the equipment and the floor.

If the studio also uses a separately labeled product for some surfaces, follow that product’s own label for that product. It is a different item from the solution you make in the Eco One. This page does not name those products, and it does not treat the Eco One or the solution it makes as a stand-in for another product’s label.

Between classes and at close of day

A between-class wipe is short and local. A close-of-day pass is the full room.

Between classes. After a group leaves, hang or roll personal mats if that is your rule, then wipe the shared mats and the gear that was just used. Remove chalk, hair, and visible dirt with a cloth, then spray and wipe with HOCl. You do not need to mop the whole studio between every class if the floor is already clear; focus on the surfaces that were just in use.

Close of day. Sweep or vacuum the floor first. Wash obvious soil off mats, gear, and counters. Then spray and wipe all shared mats, all shared gear, and the handles and switches. Mop hard floors last, with a liter you have planned for that pass. Let mats dry before you stack or roll them for the night, so you are not trapping moisture in a pile.

Work with cloths you can launder. Do not dip a dirty cloth back into the storage jug. Never mix HOCl solution with ammonia, bleach, strong acids or other cleaners; mixing with ammonia can release chloramine gas, and mixing with strong acids can release toxic chlorine gas. Add only the vinegar or additive your manual specifies, in the amount it specifies. If someone breathes in fumes or swallows solution, call Poison Help at 1-800-222-1222 (poisonhelp.hrsa.gov). If a different product was used earlier in the day, rinse that surface before HOCl goes on.

Batch planning: how many liters in a week

The Eco One makes 1 L at a time in a 1.5 L pitcher; fill only to the 1 L line. A standard cleaning liter is the 200 ppm recipe in the how-to: 2 g of food-grade, non-iodized kosher salt, 1 teaspoon of 5% distilled vinegar, the lid fitted, Setting 3 run twice (16 minutes), then a check of ppm and pH. The target pH is 5–6. How to read the papers is in HOCl PPM and pH Basics.

There is no single published “liters per studio” figure, because class count, mat area, and whether you mop all change the volume. Use these as planning ranges and then log what you actually pour for a week:

• A between-class wipe of a small yoga room, using an 8 oz spray bottle and a cloth, may use well under a liter. One 1 L batch can feed several short wipes if you cap the bottle and keep the rest in a closed jug.
• A close-of-day pass that includes mopping can use most of a liter, or more than a liter in a larger room. Plan a dedicated close-of-day batch so you are not finishing the floor with an empty bottle.
• A small studio that runs a light between-class wipe and one close each day might use one to two liters in a day, or several liters across a week. A busier martial-arts schedule, with more mat area and more closes, will use more.

An 8 oz PET spray bottle holds a little under 0.25 L, so one Eco One liter fills three bottles and still leaves a top-up in the jug. Make the close-of-day liter before the last class starts, test it, and cap it, rather than starting a 16-minute run when the room is already waiting.

If 1 L runs cannot keep up with a full week of mats, the Hypo 7.5 makes a 7.5 L (2-gallon) batch. When to step up in volume is on Choosing an HOCl Generator and compare. Machines and supplies for this use are on the store page.

Application and storage

Pour tested HOCl into a closed PET spray bottle for mat and gear wipes. A cloth or mop applies the rest to floors. Spray enough to wet the surface, wipe, and let mats dry before stacking. Do not leave an open pitcher on the front desk.

Store leftovers closed, protected from light, at room temperature or cooler, in HDPE, LDPE or PET, and re-test after storage. The full conditions and the Eco One manual’s storage statement are in HOCl Storage and Shelf Life. A studio spray bottle is a working bottle: cap it, keep it out of sun and heat, and refill it from the closed jug. Label the jug with the date, the ppm reading and the pH.

If you use a handheld sprayer, fill it only with already-made, tested solution, follow that unit’s manual, and do not skip the wash pass. This page does not give occupied-space advice or air claims. Spray only onto surfaces, never toward a person, and clear the room while you spray.

A weekly checklist

1. Count your classes and closes for the week, and estimate liters from the ranges above.
2. Keep salt, 5% distilled vinegar, test papers, and clean cloths on hand.
3. Make and test each batch; confirm pH 5–6. Do not use or store a batch below pH 4.
4. Between classes: soil off, then spray and wipe the mats and gear that were just used.
5. At close: sweep, wash, spray and wipe, mop, and let mats dry before you stack them.
6. Recap bottles, launder cloths, and re-test any jug you hold overnight or over a weekend.

Do not apply this solution to skin or to an open cut, and do not treat this routine as care for a person. Keep the work on the mats, the gear, and the room.

For the first liter, start with the Eco One and the how-to. Log what a normal week actually uses, then adjust the number of runs rather than guessing at a single published volume.
