A small panel-beating workshop generates engine oil, brake fluid, and transmission grease spills daily. Left untreated for weeks, those contaminants absorb deep into concrete pores, making removal progressively harder and turning the floor into a genuine slip hazard. If you've been putting off a proper clean because you're not sure where to start, this guide covers how to degrease a workshop floor on any surface, step by step, using the right product from the start.SK7 Superkleen is a concentrated multi-purpose cleaner with strong degreasing power, which means the same product used on a greasy workshop floor can also be diluted for tools, workbenches, equipment, washable walls and other workshop surfaces.
Why Workshop Floors Need a Proper Degreaser
Oil and grease don't sit on the surface waiting to be mopped up. On concrete especially, they penetrate, and every fresh spill on top of an old one compounds the problem. A standard mop-and-bucket approach moves the grease around more than it removes it.
Slip-and-fall incidents on greasy workshop floors are among the most common causes of workplace injuries in small manufacturing and automotive environments. Regular degreasing is a practical first line of defence, not just a housekeeping task.
Using the right workshop floor cleaner matters because:
- Mopping without a degreaser leaves a greasy film that dries invisible but stays slippery.
- Harsh acid-based cleaners can etch concrete and damage sealed or tiled surfaces.
- The longer grease sits, the deeper it bonds, and the more effort removal takes.
A purpose-built degreaser breaks the bond between oil and the floor surface, so rinsing actually clears the contaminant rather than spreading it.
Choosing the Right Degreaser for a Concrete, Tiled, or Sealed Floor
Not all floors are the same, and the degreaser you use should reflect that. Surface type determines dilution ratio more than the level of soiling does, a sealed epoxy floor needs a weaker mix to avoid breaking down the sealant, while bare concrete can handle a stronger concentration for deep penetration on set-in oil stains.
SK7 Superkleen is a multi-purpose degreaser for every job, water-based, free from harsh acids and solvents, and safe across concrete, tiled, and sealed workshop floors when used at the right dilution.
Degreaser for Concrete Floors: What to Look For
Bare concrete is porous. A good degreaser for concrete floors needs to penetrate the surface rather than just lift what's sitting on top. Look for:
- A water-based, alkaline formula, these emulsify oil without corroding the concrete.
- The ability to work undiluted on heavy soiling for older, set-in stains.
- No residue that leaves the surface slippery once dry.
SK7 Superkleen meets all three. At full concentration, it tackles deep-set oil and grease on bare concrete without requiring a pressure washer or specialist equipment.
Tiled and Sealed Floors: Avoiding Surface Damage
Tiled and epoxy-sealed floors are less porous, so grease sits closer to the surface, easier to lift, but the surface itself is more vulnerable to aggressive chemicals.
Avoid anything acid-based or solvent-heavy on these floors. With SK7, a more diluted mix (typically 1:10 to 1:20 with water) is sufficient for regular cleaning and won't break down grout, tile glaze, or epoxy sealants. For heavier build-up, step the concentration up incrementally rather than going straight to undiluted product.
How to Degrease a Workshop Floor: Step by Step
This is the practical core, a process that works whether you're cleaning a domestic garage or a small commercial workshop.
What You'll Need Before You Start
- SK7 Superkleen (concentrated)
- A clean bucket and measuring jug
- A stiff-bristle deck brush or scrubbing brush
- A mop or sponge for application (optional on large areas)
- A garden hose or buckets of clean rinse water
- A floor squeegee to push rinse water to a drain
- Safety gloves and eye protection
Clear the floor of tools, vehicles, and equipment before you start. Good ventilation helps drying time.
The Cleaning Process: From Pre-Sweep to Final Rinse
Step 1, Dry sweep the floor. Remove loose dust, metal filings, and dry debris with a broom. A degreaser works on oil and grease, not on grit that blocks it from reaching the surface.
Step 2, Dilute SK7 to the right concentration. For regular maintenance on tiled or sealed floors, mix 1 part SK7 to 10–20 parts water. For heavily soiled bare concrete, use a stronger mix, 1:1 for heavy-duty degreasing, or undiluted on localised stains.
Step 3, Apply the solution. Pour or mop the diluted SK7 onto the floor in sections. Make sure the surface is thoroughly wet rather than just damp, SK7 needs contact time to break down grease.
Step 4, Allow dwell time. Leave the solution to work for 5–10 minutes on regular soiling, and 10–15 minutes on heavier build-up. Don't let it dry on the surface. On a hot day in a South African workshop, work in smaller sections to keep the product active.
Step 5, Scrub. Work a stiff-bristle brush in overlapping circular motions. On concrete, apply firm pressure, you're working the emulsified grease out of the pores, not just the surface. On tiled floors, lighter pressure is fine.
Step 6, Rinse thoroughly. Flush with clean water, using a squeegee to push dirty rinse water towards the drain. A second rinse is worth doing on concrete to clear all emulsified residue.
Step 7, Allow to dry before use. A clean, dry surface confirms the job is done. A still-slippery feel after drying usually means a second pass is needed on that area.
Tackling Stubborn Oil Stains: Tips for Heavy-Duty Grease Removal
Old, set-in oil stains on a concrete garage floor are a different problem from fresh spills. Motor oil that's been ground in by vehicle tyres for months has bonded into the concrete at depth, and most household degreasers don't have the concentration to reach it.
For a domestic garage floor with a years-old motor oil stain, apply SK7 undiluted directly to the stain. Leave it to dwell for 10–15 minutes, then scrub with a stiff-bristle brush before rinsing. This approach consistently lifts staining that general-purpose cleaners fail to shift, without damaging the concrete surface or requiring a pressure washer.
For very stubborn stains, a second application is more effective than scrubbing harder on the first pass. Apply, dwell, scrub, rinse, then repeat on the problem area. The formula is strong enough to handle the job; it just needs adequate contact time.
As an oil stain remover for floor surfaces, SK7 works because it emulsifies rather than displaces, the oil bonds to the solution and lifts out with the rinse water, rather than being pushed to the edges of the floor.
Home Workshop Cleaning Tips: Staying on Top of Grease Build-Up
The easiest way to manage a workshop floor is to not let grease accumulate in the first place. These home workshop cleaning tips keep maintenance straightforward:
Spot-treat fresh spills immediately. A fresh oil or grease spill takes minutes to wipe up with a diluted SK7 solution. Left overnight, it starts bonding into the concrete and takes significantly more effort to remove.
Keep a ready-to-use dilution on hand. A spray bottle with a 1:10 SK7 mix is enough for day-to-day spot cleaning. Apply, leave for two minutes, wipe down.
Degrease the whole floor regularly. For a busy home workshop or small garage, a full degrease every four to six weeks keeps the surface manageable. A commercial workshop with daily spills benefits from a fortnightly routine.
Use the right size for your usage. SK7 Superkleen is available in 1 L, 5 L, and 20 L sizes. A 5 L bottle covers regular maintenance for most home workshops, while a 20 L drum makes sense for any small business cleaning weekly.
Keeping a larger bottle on hand means you're never rationing product, which is when people skip the dwell time and get a worse result.
