The product in detail
Bona SJ346 is a concentrated cleaner for compatible hardwood floors. It is used to prepare a working solution at the label dose and should not be applied like a ready-to-use spray. Before choosing it, identify the wood finish and applicator, then plan a clean, labelled dilution container.
Lifts soil from the surface of the finish. Marks that penetrate the coating need finish repair.
Listed specifications
Supplier specifications. Performance varies with configuration and conditions of use. Follow the supplied product’s manual and label.

Surfaces and compatibility
First identify the wood and its finish: varnish, polyurethane, penetrating oil or another system. A hardwood product is not automatically suitable for every finish, unfinished wood or damaged flooring.
The supplier describes the package as “1 gal (4.5 L)”. This is not equivalent to a 3.785 L US gallon; confirm the actual container volume on the label instead of inferring it from the word gallon.
Preparation and use
Confirm the cleaner is approved for the finish. Measure the label dilution and use the minimum moisture allowed by the method.
- Remove dust with a soft brush or clean dry microfibre pad.
- Check the reference, permitted finish and preparation on the label. Measure concentrate dilution precisely.
- Test the complete method in a hidden area, then inspect the result once dry.
- Apply the permitted quantity to a small area or pad as instructed. Prevent pooling around joints and baseboards.
- Replace the pad when it becomes soiled. Allow the floor to dry before walking on it.
Follow the supplied reference’s label and SDS, plus flooring and machine instructions. Do not mix products. The method guidance below complements manuals and does not set a dilution or contact time missing from them.
Care and storage
Maintain the microfibre pad and sprayer for even application. Wipe up spills promptly. Follow product storage conditions and do not store diluted solution unless the instructions permit it.
Limits and things to check
Avoid saturating wood. Black staining, swollen fibres, peeling finish or wear through to bare wood may require repair. Cleaning cannot correct failed finish or moisture damage.
Equipment, accessories and options
Plan for a measuring device, labelled container and compatible microfibre pad. Confirm exact packaging when ordering.
Practical questions
How do I check this reference suits my floor?
Identify flooring, finish and task, then check both product and flooring instructions. A hidden-area test should reproduce full application and drying. For equipment, also check tools or pads, dimensions and power supply.
Are all accessories and consumables included?
Plan for a measuring device, labelled container and compatible microfibre pad. Confirm exact packaging when ordering.
What information is still needed before purchasing?
Confirm exact net volume, dilution ratio, mixed-solution yield and floor coverage on the packaging.
