What we do
Pool acid washing that brightens without damaging
An acid wash strips a thin layer off the surface of your marbelite, taking iron stains, calcium scale, algae shadows and years of dirt with it. The result is a pool that looks two shades lighter, often dramatically so, without the cost or downtime of a full remarble.
It is a chemical process and it has to be done right. Skynet Pools uses correct concentrations, full neutralisation and a thorough rinse so the surface is brightened, not eaten away. Done well, an acid wash can buy your pool another five to seven years of life.
Our pool acid washing crews work across Pretoria East, Centurion, Waterkloof, Lynnwood, Menlyn, Garsfontein, Wapadrand, Mooikloof and the surrounding suburbs every week.

Why acid wash
What a proper acid wash does for your pool
Six reasons Pretoria homeowners book an acid wash before committing to a more expensive remarble or fibreglass lining.
Stains stripped
Iron stains, copper marks, algae shadows and calcium streaking are removed where brushing and chemicals have failed.
Brighter colour
The original tone of the marbelite is exposed again, lifting the look of the pool by several shades almost instantly.
Cheaper than remarbling
An acid wash is a fraction of the cost of a remarble and often delays a full resurface by another five to seven years.
Fast turnaround
Most acid washes take 1 to 2 working days. The pool is back in use in a week, not a month.
Proper chemistry
Correct concentrations, full neutralisation and thorough rinse so the surface is improved, not damaged.
Honest assessment
If your pool is too thin or too far gone, we will say so. We do not acid wash pools that need a remarble instead.
Our process
How we acid wash your pool
A clear path from drain down to a bright, clean surface and balanced water. Done properly, every time.
- 01
Free site visit
We inspect the surface, measure the marbelite thickness where possible and decide whether your pool is a good acid wash candidate.
- 02
Quote and plan
You receive a written, itemised quote with the wash scope and any optional grinding or refinish work. Approve before any work begins.
- 03
Drain and protect
The pool is drained safely, lights and drains are masked, and surrounding paving and plants are protected from acid splashes.
- 04
Apply the acid solution
A controlled acid solution is applied evenly, brushed into the surface and given the correct contact time to lift stains.
- 05
Neutralise and rinse
The acid is fully neutralised with soda ash and the pool is rinsed thoroughly so no residual acid is left in the shell.
- 06
Refill and balance
We fill the pool, balance chemistry, commission the equipment and walk you through how to look after the brighter surface.
Stains we remove
What an acid wash actually clears
From mineral marks to old algae shadows, acid washing handles the staining that brushing and dosing cannot.
Calcium scale
Hard white scale from high pH or hard fill water, lifted away to expose the original surface.
Iron stains
Brown and rust marks left by old fittings, borehole water or steel debris in the shell.
Copper stains
Blue and green marks from copper pipes or over-dosed algaecides, removed cleanly.
Algae shadows
Darker patches left after a green pool has been cleared, brightened back to a uniform tone.
Mottled surfaces
Patchy, blotchy marbelite evened out so the surface reads as one consistent colour again.
General dullness
The grey, tired look of an older pool replaced with a noticeably brighter, fresher surface.
How it works
Done properly, every time
Acid washing is not a casual job. The chemistry, contact time, neutralisation and rinse all matter. Done well, your pool comes back to life. Done badly, the surface is gone in five years.
Correct dilution
Acid is diluted to the right strength for your specific surface so it lifts stains without eating into the plaster.
Controlled contact time
The solution is left on long enough to work but not long enough to damage. Time matters as much as concentration.
Full neutralisation
Soda ash neutralises every drop of acid before disposal so no residual acid sits on the surface or harms the garden.

Frequently asked
Pool acid washing questions, answered
The questions Pretoria homeowners ask us most before booking a pool acid wash.
How long does pool acid washing take in Pretoria?
A standard pool acid wash takes 1 to 2 working days from drain down to refilling. Larger pools, heavily stained surfaces or grinding-plus-acid-wash combinations may take a day longer. We confirm timing before we arrive.
What does pool acid washing actually do?
Acid washing removes a thin layer of stained, scaled or discoloured plaster from the surface of the pool. It strips iron, calcium and dirt stains and brightens the pool back towards its original colour, often dramatically.
How much does pool acid washing cost in Pretoria?
Pricing depends on pool size and the level of staining. After a free site visit we send a written, itemised quote so you see exactly what is being done before approving the work.
How often should a pool be acid washed?
A well maintained pool typically only needs an acid wash every 5 to 10 years. Repeated acid washing wears the surface, so we only recommend it when staining or scale really justifies it.
Is acid washing the same as a remarble?
No. Acid washing only cleans and lifts the existing surface. A remarble removes the failed surface entirely and replaces it with new plaster. We will tell you which one your pool actually needs after a site visit.
Will acid washing damage my pool?
Done correctly, no. Done badly, it can. Our crews use the right concentrations and rinse thoroughly so the surface is brightened without being eaten away. We will not acid wash a pool that is too thin to take it.
Is the runoff safe for the garden?
We fully neutralise the acid with soda ash before any runoff is disposed of, and protect surrounding paving and plants while we work. Done correctly there is no lasting impact on the garden.
