Benefits of D/2 Biological Solution

Effective Against Biological Stains

D/2 is specially designed to remove biological stains from mold, mildew, algae, and lichens. This makes it an excellent choice for high-moisture areas such as kitchen countertops, bathroom walls, and floors, where these stains are common.

Improved Aesthetic Appeal

Regular use of D/2 helps maintain the clean and pristine appearance of floors, walls, and countertops, enhancing the overall aesthetic appeal of your home or business. Clean surfaces create a positive impression on visitors and clients.

Environmentally Friendly

D/2's biodegradable and non-toxic properties make it safe for use in environments where children and pets are present, as well as in commercial spaces where environmental regulations are stringent. It’s a responsible choice for maintaining cleanliness without harming the environment.

Safe for Users and Surfaces

The absence of harsh chemicals reduces the risk of skin irritation or respiratory issues for users. Its gentle formula ensures that surfaces are not damaged during cleaning, preserving the longevity and beauty of floors, walls, and countertops.

Long-Term Maintenance

After initial treatment of substrate, a once-a-year light spraying will help maintain a clean, stain-free surface.

Important Information

Heavy biological deposits may require repeat applications of D/2 cleaner to achieve complete cleaning after detachment. Alternatively, heavy growth can be detached by manual scraping using wooden or plastic tools immediately after application. D/2 should not be used in temperatures below 45 degrees.

This makes it environmentally friendly and safe for use around plants and on various surfaces without causing damage. It is also safe for metal and glass surfaces.

How Long Does It Take D/2 Cleaner to Work?

D/2 Biological Solution typically starts working within minutes of application. After spraying the undiluted solution on the affected area, it should be left to sit for 10 to 15 minutes. During this time, the solution penetrates and loosens biological stains. For optimal results, scrubbing with a soft brush may be necessary to fully remove the stains.

Can You Use D/2 on Granite?

Yes, D/2 Biological Solution can be used on granite. It has a pH-neutral formula that is gentle and safe for use on various stone surfaces, including granite. The solution effectively removes stains without damaging the integrity of the granite, preserving its appearance and durability.

Do You Mix D/2 with Water?

No, D/2 Biological Solution is designed to be used undiluted. The product comes ready to use, and mixing it with water is not necessary for effective cleaning.

By applying the undiluted solution directly to the stained area, users can ensure maximum efficacy in removing biological and air pollutant stains.
