What is Polyglaze Interior Protectant, and where should you use it?
Polyglaze Interior Protectant is a spray-on dressing for a car's interior surfaces that cleans, shines and protects in one step. Selleys describes it as giving dash and trim protection for a long lasting shine, and the formulation is specified to leave no oily residue — which is the characteristic that separates it from the greasy dashboard dressings the category is known for.
It is suitable for use on vinyl, leather, rubber and plastic, and it comes in 500mL bottles. The one limitation to settle before you spray anything is that it is not for use on treated surfaces. If a trim panel, seat or dash has already had a coating, sealant or aftermarket treatment applied to it, this is not the product for it.
Technical specification
| Property | Typical result |
|---|---|
| Appearance | White opaque liquid |
| Specific gravity | 0.98 – 1.01 |
| Odour | Fresh citrus odour |
| Pack size | 500mL bottle |
| Suitable surfaces | Vinyl, leather, rubber and plastic |
| Shipping / dangerous goods | Not restricted |
These figures are indicative data from the product's technical data sheet and are not intended for the preparation of specifications.
What the specification tells you in practice
A specific gravity of 0.98 to 1.01 puts the product at essentially the density of water. That is consistent with a thin, sprayable liquid rather than a heavy cream, and it is part of why the application method is spray-and-wipe rather than apply-and-buff. It goes on wet, spreads easily with a cloth, and does not need to be worked into the surface.
The white opaque appearance is worth knowing simply so you are not alarmed by it. The product looks milky in the bottle and on the surface; the finish it leaves is not white. Wiping over with a clean cloth, as the directions require, is what takes it from a milky film to an even sheen.
The "not restricted" dangerous goods classification means there are no special transport controls on it. That is a shipping classification, not a licence to be casual — the safety directions still apply, and they are listed further down.
The most useful line in the whole data sheet is the one about repeat application. Selleys does not give a coverage figure or a set number of coats; instead it says to repeat application depending on the condition of the surface, or until you are satisfied with the appearance. That is a deliberate instruction rather than vagueness. A sun-faded twenty-year-old dash absorbs far more than a two-year-old one, and the right number of passes is the number that gets an even finish on the panel in front of you.
Where to use it
- Dashboards
- Interior trim
- Vinyl surfaces
- Leather
- Rubber
- Plastic
The stated purpose is to keep the car looking new by cleaning, shining and protecting these surfaces together, rather than cleaning first and dressing second with two products.
How to apply it
- Spray the product onto the surface.
- Wipe over with a clean cloth. The cloth needs to be clean — a cloth carrying grit from earlier work will drag it across a soft vinyl or leather surface.
- Repeat the application depending on the condition of the surface, or until you are personally satisfied with the appearance.
- Wipe off any overspray on glass areas.
Step 4 is easy to skip and annoying to fix later. Overspray landing on the inside of a windscreen leaves a haze that scatters light exactly where you are looking through it, and it is far easier to wipe off while it is still wet than to clean off a windscreen afterwards. Doing the glass last, after the trim, is the simplest way to be sure you have caught it.
Limitations — where it should not be used
- Not for use on treated surfaces. This is the manufacturer's own stated limitation and it is the one to respect. Where a surface has already had a treatment or coating applied, use a product intended for that surface.
Beyond that, the safe interpretation of the compatibility list is the conservative one: vinyl, leather, rubber and plastic are what the product is stated for. A surface not on that list — glass, paintwork, fabric upholstery — is not covered by the data sheet, and overspray onto glass is specifically something to wipe off rather than leave.
Safety and storage
The stated safety directions are short and worth following:
- Avoid contact with skin and eyes.
- Use in a well ventilated area. In practice, that means opening the doors while you work rather than treating a dash in a closed cabin.
- Wash your hands after use, and before eating, drinking or smoking.
- Keep out of reach of children.
For storage, protect the product from freezing, store the container out of sunlight, and keep it tightly closed. A car care product that lives in the boot spends its life in a hot, sunlit space, which is the opposite of those conditions — a garage shelf is the better home for the bottle between uses.
Hazard classification
Polyglaze Interior Cleaner & Protectant is not classified as hazardous under the criteria of Safe Work Australia GHS 7. No hazard class is assigned to it, so it carries no hazard statements and no signal word. It is also not classified as Dangerous Goods by the Australian Code for the Transport of Dangerous Goods by Road & Rail, the New Zealand NZS5433, the IMDG Code for sea freight or the IATA Dangerous Goods Regulations for air freight — which is the same finding as the "not restricted" shipping line in the specification above, stated from the safety data sheet rather than the technical one.
What is in it
| Chemical entity | CAS number | Proportion (w/w) |
|---|---|---|
| Ingredients determined to be non-hazardous or below reporting limits | — | 100% |
The composition section of the safety data sheet is a single line. Nothing in the formulation is classified, and nothing is present above the concentration that would require it to be named, so the entire product is accounted for in one entry. That is the chemistry behind the product's own description of itself: a water-density, spray-and-wipe dressing rather than a solvent-borne one.
It is worth comparing against a stablemate. The Polyglaze Auto Protectant Wipes do the same job in wipe form, and they are classified — skin sensitisation Category 1 and eye irritation Category 2A. Two products for the same surfaces can have genuinely different hazard profiles, so a wipe being convenient does not make it the milder option.
Not classified is not the same as harmless, and the safety directions already on this page still stand. The two that have a reason behind them are ventilation and eyes. This product is sprayed, and a spray in a closed cabin is inhaled mist however benign the liquid is — open the doors. The safety data sheet notes that natural ventilation is adequate under normal conditions of use, which is what an open car door provides and a shut one does not.
Protection and storage
- Eye protection — safety glasses, if you are spraying overhead or into a confined footwell.
- Gloves — nitrile rubber is suitable for intermittent contact. Glove construction and conditions vary, so make your own final assessment.
- Ventilation — natural ventilation is adequate under normal conditions of use.
- Wash hands before smoking, eating, drinking or using the toilet, and wash contaminated clothing before reusing it.
- Storage — cool, dry and well ventilated, out of direct sunlight, away from foodstuffs and from sources of heat or ignition. Keep the container upright, tightly closed, check it for leaks, and protect it from freezing.
First aid
| Exposure | What to do |
|---|---|
| Eyes | Wash out immediately with water. In all cases of eye contamination it is a sensible precaution to seek medical advice. |
| Skin | Remove contaminated clothing and flush the skin and hair with running water. If swelling, redness, blistering or irritation occurs, seek medical assistance. |
| Inhalation | Remove the person from exposure without becoming a casualty yourself. Remove contaminated clothing and loosen the rest. Let them take the most comfortable position, keep them warm and at rest until fully recovered. Seek medical advice if effects persist. |
| Swallowed | Rinse the mouth with water. Do not induce vomiting. Give a glass of water to drink. Never give anything by mouth to an unconscious person. If vomiting occurs, give further water. Seek medical advice. |

Common questions about Polyglaze Interior Protectant
What size does it come in?
500mL bottles.
Will it leave the dash greasy?
No. The product is specified to leave no oily residue.
Can I use it on leather seats?
Leather is listed among the suitable surfaces, along with vinyl, rubber and plastic.
Can I use it on a dash that has already been treated with something else?
No. The data sheet states it is not for use on treated surfaces.
How many coats should I apply?
As many as the surface needs. The instruction is to repeat the application depending on the condition of the surface, or until you are satisfied with the appearance — an older, more porous surface will take more.
Do I need to buff it afterwards?
The directions call for spraying on and wiping over with a clean cloth. There is no separate buffing step.
It looks white when I spray it. Is that right?
Yes — the product is a white opaque liquid. Wiping over with a clean cloth evens it out.
What happens if I get it on the windscreen?
Wipe any overspray off glass areas. Doing it while the overspray is still wet is much easier than cleaning a hazed windscreen later.
