pH7X® FAQ

pH7X® is a non-caustic, oxygen-based cleaning powder for beer lines, beverage lines, transfer hoses and brewery equipment. It is made in the USA and distributed by SNP Distributors.

Yes. In our national restaurant field evaluation, 1% pH7X® delivered cleaning performance comparable to the tested 2% caustic protocol, considering ATP readings and DipSlide observations. Read the evaluation for the methods and operating conditions.

When dissolved, its sodium percarbonate releases hydrogen peroxide for oxygen-based cleaning. Disodium metasilicate contributes alkalinity and buffering. The formulation helps loosen organic residue so it can be rinsed from the equipment.

No. The reported 1% solution tests measured pH 8.6 to 8.9 in distilled water initially at pH 7.0. This is mildly alkaline. Readings vary with source water and concentration.

pH7X® uses oxygen-based cleaning at a milder working pH. The routine beer-line concentration is 1%; the national restaurant evaluation compared it with a 2% caustic protocol. Its green dye helps show when cleaning solution is present. Follow the approved handling and rinsing instructions.

Yes—repeated caustic cleaning can damage vinyl beer-line tubing over time. A 2024 study co-authored by Dr. Darla M. Goeres at Montana State University examined vinyl tubing conditioned to simulate one, two and five years of caustic and acid cleaning. Older tubing accumulated more biofilm, and biofilm in the five-year-aged tubing recovered faster after cleaning.

“While effective at controlling biofilm, repeated exposure to caustic cleaning damages tubing.”

For routine cleaning, use 38 g per US gallon or 189 g per 5 US gallons of water at 90 to 105°F. Add half the water, dissolve half the powder, then add the remaining water and powder while stirring. The guide’s household measures are approximate; weighing is preferred. Double the powder for 2%. Do not use boiling water.

For routine cleaning, recirculate for 15 minutes or allow a static soak of at least 20 minutes. The guide provides extended-soak instructions for stubborn buildup. Confirm equipment compatibility before extended soaking and rinse thoroughly afterward.

We recommend a 2% overnight soak for the first cleaning of problematic or neglected beer lines, followed by routine 1% cleaning. Confirm equipment compatibility and follow the approved mixing, handling and rinsing instructions.

Yes. Flush thoroughly with clean water and complete your rinse-verification procedure before returning the system to service. The green dye is a visual aid and does not replace rinse verification.

Yes. Contact info@snpdistributors.com for CIP dosage suited to your vessels, soils and cleaning process, and for bulk ordering. Include your vessel type, cleaning-solution volume, equipment materials, available temperature and circulation method.

Yes. We recommend quarterly acid cleaning for beer lines, with the schedule adjusted for local water hardness and mineral buildup. Follow the acid cleaner and equipment instructions. Use a separate cleaning step with thorough rinsing between chemicals; do not mix acid cleaner with pH7X®.

Cleaning and sanitizing serve different purposes. Follow the sanitation procedures required for your brewery and equipment. The reported ATP and DipSlide cleaning observations do not establish a sanitizer claim.

Wear chemical-resistant gloves and tightly sealed goggles as directed by the posted SDS. Avoid eye contact, prolonged skin contact and swallowing the product. Follow the product label and SDS for handling, storage and first aid.

Do not mix with products containing ammonia, chlorine or bleach, or with other cleaning chemicals. Do not mix or store the solution in a sealed container because pressure can build up. Follow the label and SDS.

Confirm compatibility with your equipment manufacturer for the material, dilution, temperature and contact time, especially for extended soaks. Contact us with the materials and equipment details for application guidance.

Follow the posted SDS and applicable wastewater requirements. The current SDS states that the product must not reach sewage; that wording is under review with our blender. Contact us for guidance for your application. A milder working pH alone does not establish permission to discharge used solution.

In the reported 15-minute restaurant field comparison, faucet ATP readings after cleaning were 1 and 0 on the two 1% pH7X® lines and 2 and 0 on the two 2% caustic lines. DipSlide observations also supported comparable cleaning performance under the tested conditions. The treatments used different lines with different starting conditions; see the complete methods and results.

Yes. Following two eight-week evaluations, the national restaurant and brewhouse group approved pH7X® and made the switch. The published report records approval by its brewing leadership and Board for use across all 219 locations at the time. The linked evaluation identifies the customer and explains the results.

Yes. During the evaluation, Oscar, the group’s West Covina Head Brewer, filled a particularly dirty, problematic beer line with a 2% pH7X® solution for a nine-hour soak. The following flush released accumulated material identified by the evaluation team as biofilm. Watch the demonstration and read the accompanying field evaluation.

Breweries, restaurants and beer-line service companies use pH7X®. Examples include New York Beer Project in Lockport, New York; Alvarado Street Brewing; Big Trout Brewing; Monolith Brewing; and Aggieville Brewing Co.
