GENERAL PURPOSE CLEANING SOLUTION

HI7061L is a general purpose cleaning solution that can be used for a variety of applications

Electrodes can become dirty from use and will produce inaccurate results even as they read correctly in a pH buffer. Hanna’s cleaning solutions eliminate impurities and residues that are left on electrode surfaces when immersed in samples during measurement or when stored incorrectly. Hanna suggests cleaning the bulb and junction of your electrode on a regular basis to ensure that the probe is always clean and to prevent any clogging of the junction.

• Specially formulated for cleaning electrodes
• Air tight seal to ensure quality
• Expiration date and lot number

The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note, because during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration. pH meters on the market today will allow an offset voltage of approximately ±60 mV. The deviation from 0 mV is not unusual but ideally should be no greater than ±30 mV. The calibration process compensates for the change in offset voltage.

If the mV offset continues to deviate and the meter is calibrated with a dirty electrode then inaccurate readings will result. Cleaning is a fast and effective routine that should be performed on a regular basis as a preventative measure against using a dirty electrode and to ensure that the junction is not clogged. By simply immersing the electrode in the HI7061L cleaning solution for 15 to 20 minutes will dissolve any mineral deposits or other coatings.

Q&A

What is a general‑purpose cleaning solution?

A general‑purpose cleaning solution is a ready‑to‑use or concentrate cleaner formulated to remove a wide variety of common soils such as dirt, grease, oils, dust, and grime from many water‑safe hard surfaces. It is designed for everyday cleaning tasks rather than specialized jobs like heavy degreasing or electronics cleaning.

Where can a general‑purpose cleaning solution be used?

These cleaning solutions can be used on many surfaces including floors, walls, countertops, sinks, cabinets, tiles, and more. They are suitable for homes, offices, kitchens, bathrooms, and commercial spaces when used according to the label directions. 

What ingredients are typically found in general‑purpose cleaners?

General‑purpose cleaners often contain surfactants to help wet and lift soils, solvents to dissolve dirt and grease, and chelating agents to bind minerals. They may also include mild detergents and pH adjusters to improve cleaning effectiveness while being safe on common surfaces. 

Are general‑purpose cleaners safe for daily use?

Many general‑purpose cleaners are formulated to be safe for daily use on most water‑safe surfaces. Some eco‑friendly options use biodegradable ingredients and avoid harsh chemicals, making them safer for use around people, pets, and food preparation areas when used as directed. 

How do you use a general‑purpose cleaning solution?

Depending on the product form, a general‑purpose cleaner can be sprayed directly on a surface and wiped with a cloth, diluted with water for mopping or larger surface cleaning, or applied via sponge or mop. Instructions on dilution and contact time are provided by the manufacturer.

What is the difference between a general‑purpose cleaner and a specialized cleaner?

A general‑purpose cleaner is designed for broad, everyday cleaning tasks across many surfaces, whereas specialized cleaners are formulated to handle specific challenges such as heavy grease, mineral scale, or delicate materials like electronics or fabrics. 

Do general‑purpose cleaners also disinfect?

Some general‑purpose cleaners include disinfecting agents, but not all do. Products labeled solely as general‑purpose cleaners focus on removing soils, while disinfectants specifically kill microbes. Always check product labeling for sanitizing or disinfecting claims.

Why choose a general‑purpose cleaning solution?

Using a general‑purpose cleaning solution simplifies routine maintenance because one product can handle a wide variety of common cleaning tasks, reducing the need for multiple specialized cleaners in everyday environments.
