Grease trap treatment for restaurants, hotels and commercial kitchens.
Busy kitchens generate fats, oils and grease every service. Left alone, FOG coats drain walls, turns grease traps septic and produces the sour smell that gets flagged on hygiene audits. J-All's biological grease trap treatment digests FOG at source — so drains stay clear, smells disappear within days and jetting call-outs drop.
Signals we hear from restaurants & hotels.
- Sour or eggy smell from floor gullies during or after service
- Grease trap needing emptied more often than the contract allows
- Recurring slow drains behind the wash-up or under the wok range
- EHO or hygiene auditor comments on drainage or odour
- Emergency jetting invoices creeping up every quarter
Outcomes for restaurants & hotels.
- FOG digested at source — grease trap stays functional between empties
- Kitchen and back-of-house smells gone in 24–72 hours
- Fewer emergency jetting call-outs and blocked-drain incidents
- Safe for staff, no PPE beyond normal kitchen hygiene
- Documented dosing schedule for your food safety records
Results vary by site. Reduction ranges, timelines and dosing rates shown are typical outcomes from comparable UK installations and depend on influent load, temperature, retention time, existing plant condition and the agreed dosing regime. A J-All specialist will confirm expected performance after a site assessment.
Why chemistry-only keeps failing.
Grease trap odour, FOG build-up, blocked kitchen drains and failed hygiene inspections. These are biological problems at their core, so they keep coming back until the biology gets fixed. Bleaches, acids and dispersants push the symptoms downstream but leave the FOG, sludge, hydrocarbon or ammonia load untouched.
Grease Trap & FOG Treatment
Uncontrolled fats, oils and grease behave like an oil spill inside your drains. J-All's LO-FOGS blend breaks down the carbon links quickly and safely, keeping grease traps sweet, drains free and inspections painless — for restaurants, hotels, care homes, schools, takeaways and food manufacturers.
