If you run a commercial kitchen in South Africa, grease is your daily enemy. It coats extraction hoods, clogs fryer surrounds, and builds up on tile walls faster than most cleaning schedules can keep pace with. Choosing the right heavy duty degreaser for commercial kitchens is not a minor purchasing decision, it affects hygiene scores, fire risk, staff safety, and your bottom line. This page compares SK7 Superkleen directly against generic chemical degreasers on the metrics that matter most to South African food-service operators: safety, surface suitability, and true cost-per-litre.
Why Commercial Kitchens Need a Heavy Duty Degreaser Built for the Job
Standard household or office-grade cleaners are not formulated for the volume and type of grease a busy restaurant produces. Commercial kitchens generate polymerised cooking fat, baked-on, oxidised residue that bonds to metal, grout, and concrete under repeated heat cycles. A general-purpose cleaner will not shift it without extended dwell time, aggressive scrubbing, and multiple applications.
A degreaser built for commercial kitchen use cuts through that residue on contact, works across multiple surface types, and is safe enough to use in an environment where food is present nearby.
The Real Cost of Grease Build-Up in a Restaurant Kitchen
The costs of inadequate degreasing go beyond a dirty kitchen. Grease fires are a well-documented risk in commercial kitchens, so regular degreasing is a safety and compliance necessity, not just a hygiene preference. A grease-clogged extraction hood is a fire hazard, and a failed health inspection means closed doors and lost revenue.
There are operational costs too. Baked-on grease left too long requires stronger chemicals, longer labour hours, and more product to shift, making poor degreasing a compounding expense. The smarter approach is consistent, effective cleaning with a product that does the job in fewer steps.
SK7 Superkleen vs Generic Chemical Degreasers: Head-to-Head Comparison
Generic chemical degreasers sold in South Africa typically fall into two categories: caustic alkaline formulas (high-pH, sodium hydroxide-based) and solvent-based sprays. Both work on grease, but both carry trade-offs, corrosive residue risk, strong fumes, restricted use near food surfaces, and often poor dilution economy.
Here is how SK7 Superkleen compares directly:
| Factor | SK7 Superkleen | Generic Caustic/Solvent Degreasers |
|---|---|---|
| Harsh chemicals | No caustic or heavy solvents | Often contains sodium hydroxide or petroleum solvents |
| Food-adjacent surface safe | Yes, mild alkaline pH | Risk of residue and corrosion on stainless steel |
| Dilution / yield | Concentrate, 1 L yields multiple litres of usable product | Many are ready-to-use, no dilution benefit |
| Multi-surface suitability | Tiles, stainless steel, concrete, hoods, fryers | Often restricted, caustics can damage grout and aluminium |
| Fume / ventilation risk | Low | High, especially solvent-based products |
| Eco credentials | No harsh chemical formulation | Can be less favourable, some formulations contain solvents or caustics that take longer to break down |
Safety on Food-Adjacent Surfaces
Caustic degreasers work by saponifying fat, a chemical reaction that requires a high pH, typically above 12. That pH level is effective on grease but damaging to surfaces like aluminium extraction fans, tile grout, and sealed concrete. More critically, chemical residue left on a stainless steel prep bench, if not rinsed thoroughly after cleaning, can pose a food-contamination risk.
A restaurant extraction hood cleaned with a caustic degreaser carries residue risk on surrounding stainless steel. SK7's mild alkaline formulation reduces that risk on food-prep surfaces nearby. In a working kitchen where a surface cleaned at midnight is back in food-contact use by 6am, that difference matters.
Cost-Per-Litre and Value Over Time
Ready-to-use solvent sprays are sold by volume, but that volume is mostly water or carrier solvent. You are paying for the convenience, not the chemistry.
A 5 L concentrate that dilutes at a ratio suited for heavy grease yields significantly more usable product than the same volume of a ready-to-use solvent spray. The true cost-per-litre comparison favours SK7 once dilution is factored in. For a busy restaurant or catering kitchen that consumes product daily, that yield difference compounds into meaningful savings across a month.
Food Safe Degreaser South Africa: What the Labels Don't Always Tell You
In South Africa, food-contact cleaning chemicals are generally expected to be formulated so they won't contaminate food, and disinfectants used in food environments can fall under standards such as SANS 1828 or the Foodstuffs, Cosmetics and Disinfectants Act. Not every product on the market carries formal third-party certification for every use case, so it's worth understanding what "food safe" means in practice rather than relying on the phrase alone.
In a South African food-service context, "food safe" for a degreaser practically means three things:
- Mild alkaline pH, the cleaner does not leave a chemically active residue that alters food or damages food-contact surfaces.
- No persistent solvent or heavy metal content, the formula rinses clean and does not accumulate in grout lines or porous surfaces adjacent to food prep.
- Safe handling without specialist PPE, staff can use the product without respirators or full chemical-resistant gear, reducing the risk of errors in a fast-moving kitchen environment.
SK7 Superkleen's formulation avoids harsh caustics and heavy solvents, which is designed to reduce residue risk on food-adjacent surfaces compared with high-pH caustic alternatives. SK7 does not currently hold formal food-safety certification (such as SANS 1828), so if your kitchen has a specific compliance requirement, check our Safety Data Sheet or get in touch to confirm SK7 is the right fit.
Where SK7 Works in a Commercial Kitchen Environment
SK7 Superkleen is not a specialist product designed for one surface. That versatility is a practical advantage, one product, one dilution system, across the whole kitchen.
Industrial Kitchen Degreaser Applications
As an industrial kitchen degreaser, SK7 handles:
- Extraction hoods and canopy filters, heavy, polymerised grease that accumulates fastest
- Fryer surrounds and splash zones, high-temperature cooking fat that bonds to painted and bare metal
- Stovetops and burner surrounds, carbonised residue requiring dwell time and agitation
- Tile walls and splashbacks, grease that migrates and settles on vertical surfaces
- Concrete kitchen floors, oil and fat that penetrates if left unaddressed
As a grease remover commercial operators rely on, SK7 cuts the cleaning cycle on these surfaces, reducing product volume and labour time compared to weaker alternatives that require repeat application.
Surfaces SK7 Is Safe to Use On
SK7 is suitable for use on:
- Stainless steel benches and equipment
- Ceramic and porcelain tiles
- Oven doors (external surfaces)
- Extraction hoods and ductwork (accessible sections)
- Painted concrete and sealed floors
- Aluminium surfaces (where caustic alternatives would corrode)
This range makes SK7 a true multi-purpose degreaser for every job in a commercial kitchen, rather than a product you use only on the fryer before reaching for something else on the tiles.

How to Use SK7 as a Restaurant Kitchen Cleaner: Dilution and Application
SK7 Superkleen is a concentrate, so dilution ratio determines both performance and economy. Getting this right means you use less product, cut grease faster, and avoid waste.
Dilution guide:
- Light grease / daily maintenance, dilute at a higher ratio (more water per part SK7). Apply, wipe, and rinse. Suitable for daily wipe-downs of benches and stovetops.
- Heavy grease / weekly deep clean, use a stronger dilution (less water, more SK7 concentrate). Apply directly to the surface, allow a dwell time of 3–5 minutes, agitate with a brush or cloth, then rinse thoroughly with clean water.
- Extraction hoods and fryer surrounds, apply the heavier dilution undiluted to the worst build-up areas, allow to dwell, then work in sections with a stiff brush before rinsing.
Application tips:
- Pre-rinse the surface with warm water to loosen surface debris.
- Apply SK7 solution evenly, a spray bottle works well for vertical surfaces.
- Allow full dwell time before agitating. Do not rush this step.
- Rinse completely with clean water to remove all residue.
- No specialist PPE is required for standard use, but gloves are recommended for concentrated applications.
Used consistently as a restaurant kitchen cleaner on a daily and weekly schedule, SK7 prevents the heavy build-up that makes deep cleaning a multi-hour ordeal. The concentrate format means a 5 L or 20 L purchase goes further than the label volume suggests, making it the straightforward, cost-smart choice for South African commercial kitchens ready to move away from outdated caustic chemistry.
