How BrightShield works
BrightShield is Guardian’s engineered chemical cleaning program for industrial equipment. Every job follows the same six steps:
- Insight Audit. A Guardian account manager surveys the system and the people who run it, learns its history, agrees the objectives and sets the KPIs the clean will be judged against. Audit guides cover exchanger fouling, oil removal and after filters, amine systems, H2S scavenging and wash bays.
- Foulant Fingerprint Analysis. Our lab identifies what the deposit is made of and how severe it is, using a standard test matrix of internal and external analyses.
- Precision Chemistry Selection. We bench-test candidate chemistries against your deposit, alongside a blank and your current program, and set the application method: online or offline, once-through, circulation or soak, temperature, flow, volume, injection points and materials compatibility.
- Program Proposal. You get a written program built from the audit, the analysis and the screening results.
- Implementation and Assurance. Guardian supports the job on site with live monitoring, working with your crew or your preferred application contractor. Your account manager stays involved through the application.
- Validation Report. After the clean, we report the results against the KPIs agreed in the audit.

What Happens When You Request a Recommendation
A Guardian industrial cleaning specialist will contact you to understand your application, your deposit, and your cleaning challenges.
Our team will review your deposit, surface, and operating conditions — and if needed, our lab will test your soil to identify the most effective chemistry.
We’ll provide a product recommendation, application guidance, and a quote — with no obligation to proceed.
If the solution makes sense for your operation, we’ll arrange supply, provide application training, and support you from day one.
Why off-the-shelf cleaning falls short
Industrial fouling is rarely one thing. Heavy hydrocarbons, asphaltenes, scale, iron sulphide and solids build up in layers, and the mix changes from one unit to the next. Cleaning without knowing the deposit leads to extra chemical, repeat cleans, mechanical work and waste you did not plan for. It also leaves hazards such as H2S, LEL vapours, benzene and pyrophoric iron sulphide to be handled on the fly.
BrightShield starts by identifying the deposit, then designs the chemistry and the method around it.
Published BrightShield results
- Heat exchangers: two fouled exchangers at an oil sands facility back in service in under 24 hours without mechanical lancing, with flow up 150% on one unit and 400% on the other.
- CSS exchanger, Cold Lake: flow raised from under 20 m³/h with the valve fully open to 50 m³/h at half open, using 50 L of product and no shutdown.
- Produced water coolers: chemical use per cleaning cut by more than half and cleaning frequency nearly halved, then a further 13.4% cost reduction after moving to a two-product program.
- Oil removal filters: walnut shell media cleaned without caustic, avoiding the pH damage the previous program caused.
- Tank cleaning: more than 700 m³ of sludge removed, H2S eliminated and mercaptans cut 77%, with solids kept suspended for compliant disposal.

Chemistry is half of it. The other half is who picks up the phone.
Guardian has manufactured specialty chemicals since 1960. BrightShield brings together the account manager who knows your site, a subject matter expert and our lab, and the account manager stays involved through the application. When something is not working the way it should, you call someone who has seen the unit.
Custom Formulations
We don’t force-fit products from a catalog. Our R&D lab analyzes your deposit and formulates the right chemistry for your exact application—deposit, surface, temperature, and operating conditions.
Technical Support
Product selection is just the start. We provide deposit analysis, dilution guidance, field trials, application training, and ongoing program optimization. We’re there when you need us.
Safety-Forward Chemistry
High flash points (>95°C), ultra-low VOC, and VOC-free formulations, with less fire risk and solvent vapour than conventional solvents. Our chemistry meets or exceeds Canada’s VOC legislation.
Proven in the Field
65+ years serving oil sands, mining, manufacturing, transportation, and heavy industry. 4,000+ clients across North America trust Guardian.

Frequently Asked Questions: BrightShield
BrightShield is Guardian’s engineered chemical cleaning program for industrial equipment such as heat exchangers, produced water coolers, filters, vessels, tanks and pipelines. It runs in six steps: an Insight Audit, a Foulant Fingerprint Analysis, bench-tested chemistry selection, a written program proposal, on-site implementation with live monitoring, and a validation report.
It is the first step of a BrightShield job. A Guardian account manager reviews the system, its history and your objectives, and agrees the KPIs the cleaning program will be measured against.
A standard lab analysis that identifies what your deposit is made of and how severe it is, using a combination of internal and external tests. The results drive which chemistries are screened.
Heat exchangers, produced water coolers, piping, vessels, storage tanks, oil removal and after filters, transport tankers and pipelines. Insight Audit guides also cover amine units and industrial wash bays.
Often. In one published job, two fouled exchangers were back in service in under 24 hours without lancing, with flow up 150% and 400%.
Yes. Degassing and decontamination are part of the program. In one tank cleaning job, H2S was eliminated and mercaptans cut 77% while vapour levels were monitored continuously.
Your crew or your preferred application contractor, with Guardian on site to monitor and support. Your Guardian account manager stays involved through the application.
A validation report compares the results with the KPIs agreed in the Insight Audit, such as flow rate, pressure, sludge volume or vapour levels.
Yes. Programs are planned around your turnaround window, and chemistry and method are chosen with the time available in mind.
