This is probably alloy oxidisation. This is a natural effect common on exposed aluminium and Simoniz Alloy Wheel Cleaner is ideal for removing it. However if your alloy wheels are coated with a lacquer and you are seeing this white material, it suggests that the lacquer is beginning to break down, allowing air and moisture to reach the alloy. It will be more difficult to clean and in severe cases you may need to have the wheels stripped and re-lacquered.

Yes. BS6580:1992 includes requirements to ensure that the anti freeze meets stringent corrosion protection standards. Holts antifreeze meets these standards and helps prevent corrosion build up in the cooling system. This is why it is recommended that anti freeze is maintained at the correct strength all year round.

Yes. M.E.G. remains unaffected by heat and therefore will not evaporate and lose its effectiveness, unlike methanol based antifreezes.

Yes. All the components of Holts antifreeze including the corrosion inhibitors are chosen to be compatible with both cast iron and aluminium engines.

Yes. They contain a blend of several silicones to assist application and to give long lasting protection.

Yes. The materials used are actually colourless and therefore suitable for all colours. The name Back to Black derives from the time when you could have any colour trim "as long as it was black."

To remove any streaking work white spirits into the area with a toothbrush. Clean the surface and apply Simoniz Back to Black. To achieve the perfect finish a number of coats may be required.

Yes. It is able to be used on most chrome objects, but we would always recommend that you test the product on a small inconspicuous area first to ensure suitability.

Due to the resin system used in this specialist decorative paint it is not recommended to overcoat the product. Some measure of protection can be achieved by a very gentle application of a very mild or non abrasive polish such as Simoniz Max Wax.

Ensure the dashboard is free from any wax based cleaning agent and then polish with Simoniz Dashboard Shine. Keep a Dash Bright to hand for easy valeting.

Use Simoniz Matt Dashboard Cleaner which cleans and removes ingrained dirt and superficial marks from the dashboard. It leaves a natural, non-reflective finish with no slippery residue.

Colour Restorers should only be used infrequently to restore badly faded or oxidised paintwork. They contain an abrasive that removes a very thin layer of paint which then exposes a layer of fresh paint. The new layer of paint should be protected by a good quality polish such as Simoniz Max Wax or Simoniz Original Wax.

No. De-Icer contains a hydrocarbon propellant which is a highly flammable propane / butane mix and also contains agents which can affect plastic etc used on domestic appliances.

Upholstery Cleaner is general purpose cleaner which will remove everyday dirt and soil from a variety of materials and surfaces. It will also remove some light stains of some substances. However this will depend on several factors such as what has caused the stain, what the stained material is and how long the stain has been there. If Upholstery Cleaner is unsuccessful it will be necessary to use a specialist stain removing product.

For best results apply the paint on a warm, dry day or inside a heated, but well ventilated garage. To achieve a professional finish ensure the surface is dry, clean and grease free before use.

When spray painting in good conditions (above 15°C, dry conditions, etc) we would recommend the following timings/instructions:

1. Primer coatings:  Apply several light coats, leaving about 10-15 minutes (allow the paint to become 'tacky') between each one, which makes sure that all solvents have evaporated off and will not be trapped between the layers which can lead to bubbles forming between the layers.
2. Primer -> Colour:  The primer stage once completed should be left to dry for at least 2 hours, wet and dry paper should then be applied to achieve a smooth finish.
3. Colour coatings:  Apply several light coats, leaving about 10-15 minutes (allow the paint to become 'tacky') between each one, which again makes sure that all solvents have evaporated off and will not be trapped between the layers which can lead to bubbles forming between the layers.
4. Colour -> Lacquer:  We would recommend that the lacquer is applied 45-60 minutes after the last coat of the metallic colour paint.
5. Lacquer coatings:  Again apply several light coats, leaving about 10-15 minutes (allow the lacquer to become 'tacky') between each one, which makes sure that all solvents have evaporated off and will not be trapped between the layers which can lead to bubbles forming between the layers.
6. Finishing Touches:  If any finishing touches are required (removing overspray etc) we would then recommend leaving the lacquer and paint to fully dry/harden for a week (7 days), before anything is used to cut it back etc.

If spraying in colder conditions we would recommend extending the drying times, but please be aware that when spray painting in cold conditions dampness from the atmosphere has the potential to be picked up by the paint and cause a few different problems including a matt/flat finish or a milky bloom forming.

No, and is safe in temperatures up to 1000oC.

The cause is probably residual road grime on the windscreen wipers spreading across the screen when you switch on the wipers. The best way to avoid this is to clean the wiper blades using glass cleaner on a clean cloth or tissue at the same time as you clean the rest of the glass. Don't forget the rear windscreen wiper blade as well.

For smear free driving frequent use of a good quality screenwash will also help.

Add a small amount of water to the paste and this will soften it ready for use.

No. The pigments necessary to manufacture very high temperature paints provide a matt finish only.

Yes. It is able to be used on most leather furniture, but we would always recommend that you test the product on a small inconspicuous area first to ensure suitability.

Molyslip can be used on diesel engines and can also be used on turbo charged engines, provided that the engine runs on mineral oil.

No. Holt's No Mix cures in ultra violet rays, which are only found in natural daylight. No Mix will not cure if left in the garage or in a window - the product must be placed in outside daylight.

It is not recommended as due to the design of a 2 stroke engine, the product could contaminate the crankshaft.

We recommend that you do not use Piston Seal in diesel engines.

Yes, not only does waxing leave a high shine on your vehicle it is also highly effective in removing surface oxidation and road grime build up. The clear film of wax that is left on the vehicle after polishing acts as a protective layer to your finish and helps to make water bead and easier to shed thus reducing environmental damage to your paintwork.

Waxing every 90 days is sufficient for vehicles exposed to the highest level of environmental elements, dependent upon type of polish used.

To apply, undo the top hose and pour directly into the system. Do not apply through expansion bottle.

Holts Radweld is the UK's number 1 radiator repair. It permanently seals all radiator leaks and also contains rust inhibitors. It is unaffected by anti-freeze.

This statement was made by Rover to all manufacturers of radiator sealants, as it was considered that these 2 models could suffer a malfunction of their capillary housing unit, being narrower than other vehicles.

The most direct and best method of application is through the top hose, however the product will still circulate into the system if applied through the expansion bottle.

Yes, Radweld can safely be used in alloy radiator systems. Extensive tests were carried out when the product was launched in 1980 to reveal this.

This should not cause any damage but we would recommend that the fuel tank is topped up to dilute the mix.

Although the majority of handbooks advise against using additives in new cars, to do so would not be detrimental to the car. However before using any additive we strongly recommend that you check that your warranty will not be affected.

Simoniz Rubbing Compound is heavy duty cleaner, designed to blend in new paint-work, restore very dull and badly weathered paint-work.

Polish the wheels with an abrasive cutting agent, such as Simoniz Rubbing Compound or Simoniz Chrome Cleaner. Both of these products contain abrasive materials which will remove stubborn stains. If required you can finish off with a milder abrasive material such as Simoniz Colour Restorer.

Would you use Car Shampoo to clean your dishes?

Dish detergents are designed to be used in hot water and to cut through grease - therefore they are likely to penetrate the wax, leaving your car unprotected. Also, many washing up liquids contain salt as a thickener, which will lead to rust and damaged metalwork over time. We recommend Simoniz Wash and Wax - this is a powerful yet mild detergent designed to remove stubborn dirt, grime and other harmful deposits, and to leave a protective layer of Simoniz wax.

Spray Grease is mineral based and does not contain any Silicone or Graphite.

Holts Spray Grease is not recommended for Motor Cycle chains with rubber 'O' rings. We recommend you use Holts Universal Chain Lube, which is compatible with rubber 'O' rings and has anti-fling properties.

Yes you can but it will only remove ordinary dirt and grime, it will not remove oxidisation.

Yes

No

With over 28m cars in the UK and 7.3 million punctures on British Roads every year = 1 in 4 chance of developing a puncture. On average a car user will incure a puncture every 38k miles. Tyreweld eliminates the need for immediate tyre change. The product is endorsed by the National Tyre distributors association

Tyreweld is a water based latex emulsion (milky white solution) which coats the inner if the tyre, locating and temporarily sealing the puncture and developing a protective latex film over the top. Tyreweld can be removed with soapy warm water, the tyre dried and then in accordance with British Standards the tyre buffed on a buffing wheel. This will roughen the surface to provide an adequate key to take the patch ensuring all residual dry latex will be removed and nothing will remain to react with the patch or adhesive.

The Tyreweld solution is transferred into the tyre via the valve connector, providing enough pressure to re-inflate the tyre. When the car is driven at a reduced speed (do not exceed 30mph) the centrifugal force distributes the solution around the tyre which 'cures' to provide and effective 'get you home' repair. At the earliest opportunity the tyre must be taken to a Professional Tyre Repairer for appropriate attention.

In the event of an emergency puncture repair situation. Tyreweld is not a permanent repair but is designed to get you home. The tyre should then be repaired or replaced depending on the severity of the puncture. Tyreweld is not suitable for large holes or repairs to the tyre wall. Do not use where the tyre has been displaced from the rim.

Considerable success has been achieved with Tyreweld in tubeless tyres with punctures upto 5mm in diameter. However the effectiveness of the product is reduced with tubed tyres. Tyreweld is not suitable for tyres that have side wall damage or when the tyre has come off the rim due to driving for a prolonged period with a flat tyre.

Because of Tyrewelds liquid formulation spreading itself evenly around the tyre when driven prior to it fully curing it should not affect wheel balancing. Also because cars must be driven at a reduced speed not exceeding 30mph/45kph, any minor effects on wheel balance will not be observable.

Tyre width up to 155mm use 300ml

Tyre width over 155mm use 400ml

4x4 and larger tyres use 500ml

Yes. Should the tyre be safe to repair, Holts Tyreweld can be flushed out of the tyre. Always follow the advice of the Tyre repairer.

Regular tyre maintenance is an easy and inexpensive way to prolong the life of tyres. Check tyres regularly either at home or when visiting a garage or filling station.

This is the only product to be endorsed by the National Tyre Distributors Association.

This is probably a phenomena known as water spotting.

It isn't fully understood but usually affects red, dark blue or green cars and the paintwork is usually already in a fairly poor condition, or the car has had a respray.

What is thought to happen is that when paint in this condition has a polish applied, any rain that falls shortly afterwards forms beads which act like magnifying glasses. These intensify the rays of the sun and cause "bleaching" of the pigments in the paint.

It is usually necessary to cut back the top layer of paint to remove the water spots. This can be done with Simoniz Colour Restorer or in very severe cases Simoniz Rubbing Compound. Once the water spots have been removed the newly exposed paintwork should be protected with a good quality wax polish such as Simoniz Original Wax.

The product will work on a diesel engine but we recommend that the injectors are left in place.
