D/2 Biological Solution - 5 Gallon Pail

$207.95
Add Drum Faucet - 3/4" Opening?

Size: 5 Gallon Pail

The large cap on the 5 gallon pails is very tight. If you do not have a faucet, we highly recommend adding the reusable faucet. Puncture the spot where the faucet screws in, and screw faucet into place.  Otherwise, large pliers can be used to remove the entire cap.

D/2 Biological Solution is a biodegradable, easy to use liquid that removes stains from mold, algae, mildew, lichens and air pollutants. It is effective on marble, granite, limestone, brownstone, travertine, masonry, terra cotta, concrete, stucco, wood, and other architectural surfaces including monuments, sculpture and headstones. A contact time of only 10 to 15 minutes followed by scrubbing with a soft nylon or natural bristle brush will loosen most biological and air pollutant staining.

D/2 Biological Solution is effective for removing harmful biological and air pollutant staining from many building materials including masonry, marble, granite, limestone, brownstone, travertine, terra cotta, concrete, stucco, wood, canvas and vinyl & aluminum siding.

  • How much would it be to ship a 5 gallon container of D/2 to the zip code 75801 (Palestine, TX)? Thank you.

    The easiest way to find out shipping cost is to add the product(s) to your cart and go to through the checkout.
    The shipping will be calculated and tell you the total before you pay.

  • Can the quart spray bottle of D2 Biological solution be used to refill the gallon solution?

    Yes, I would advise to use a funnel when filling spray bottles.

  • Is there an "average" number of headstones (typical size - not large monuments) that can be cleaned with a 5 Gallon undiluted solution? I need to clean approx 50 headstones. Thanks!

    The manufacturer specifications estimate coverage of 250-350 square feet per gallon. A 5 gallon container will do 1,250-1,750 square feet. The range depends on the porosity of the stone.
    About 35 upright marble veteran tablet stones (like in Arlington National Cemetery) can be cleaned with 1 gallon of D/2 Biological Solution.
