Clean Alloy Trays and bullbars

Hi All,
Any tips for cleaning an Alloy Tray?
How or what should i do to look after it?
also I have an hilux 2x4. I have a rather larger Bullbar to go on it. Will the weight of the bull bar damage my vehicle in any way?
Cheers

Hi Brandon, for doing alloy trays, a mate uses this in his detailing shop at about 50/50 or less, wets the tray down first, then sprays it on and jet washes it off. Comes up like new.http://www.septone.com.au/content.asp?item_cat=13&industry=transport...cheers unc

Another good product for cleaning aluminium is "ALU-CLEAN" made by Cyndan Chemicals
See their website www.cyndan.com.au

If its an alloy bar it shouldnt stress your suspension too much.

I guess an alloy bar would weigh around 40 kgs ,get a small person to sit on the bonnet and note the clearance before and after.

Most of the cleaners suggested here contain as their primary constituent hydroflouric acid - which does work a treat on aluminium - no two questions - it is the jujuj for cleaning alluminium.

The trouble is the potential poisoning downsides!

You can die from breathing this stuff & from skin contact with it - not to tmention the obvious swallowing it in liquid form or getting it in your eyes or on ya johnson! ;o)

This stuff is bad jujuj for anyone and really shopuld be avoided unless you know what your doing and have the full air rebreather space mans safety suit etc etc to apply and wash it off.

You see the Hydroflouric acid has really nasty side effects - this from the MSDS sheet should convince you-

Advice to Doctor
Inhalation: Acute respiratory failure may develop requiring airway support, 100% oxygen and positive end expiratory pressure treatment for pulmonary oedema. In addition, treatments and monitoring for systemic fluoride poisoning described above may be required.
Skin contact: Calcium gluconate gel applied topically will often relieve the pain and reduce the injury. Exposure of subungal tissue may require the removal of the nail in order to treat adequately. Continued pain and destruction may be treated by subcutaneous administration of calcium gluconate. Arterial calcium perfusions have been used.
Systemic fluoride poisoning can result from dermal exposure, particularly with extensive exposures. The treatment described above needs to be considered. Early removal of skin may need to be considered in cases of extensive skin damage and refractory hypocalcaemia.
Continue application of the calcium gluconate gel to the skin for 15 minutes after the pain has completely subsided. This may require several hours but, providing improvement in the lesions and symptoms continues, massaging with the gel should be continued. In cases where a thick necrotic coagulum has formed, it may act as a barrier and prevent the penetration of the gel. This will be indicated by lack of improvement. In these cases, the necrotic tissue should be excised and the gel massaged into the base of the burn, taking usual aseptic precautions.
If the burn fails to respond to the calcium gluconate gel, injection of a sterile 10% solution of calcium gluconate into and under the burn should be considered. Relief of pain is an indication that sufficient solution has been injected. Because of this, an anaesthetic should not be given except in situations where the skin is tightly adherent to the underlying tissues. In these cases, a general anaesthetic should be given as local anaesthesia is contra-indicated.
Once symptoms have subsided, the burn should be covered with a sterile dressing. If the pain recurs, the patient should return for further symptomatic treatment.
In cases of large areas of skin contamination, for example, greater than 65 sq cm, six effervescent tablets, each containing 400 mg calcium and 20 mg ascorbic acid, should be given in water by mouth every two hours until the patient is admitted to hospital.
Serum calcium and / or magnesium may have to be replaced intravenously if indicated by clinical signs or by electrolyte monitoring. Systemic administration is by the slow intravenous route.
Eye contact: Irrigation with water and isotonic saline and obtain an opthalmologic consultation.
Ingestion: Nasogastric suction with calcium gluconate solution may reduce systemic fluoride toxicity. The possibility of chemical burns to the gastrointestinal tract needs to be kept in mind. Acute systemic fluoride poisoning may cause profound hypocalcaemia (hypomagnesaemia) requiring intravenous calcium (magnesium) therapy. Electrocardiogram results and blood calcium / magnesium need to be monitored in acute systemic fluoride poisoning.

The reference to hypocalcemia - means this stuff eats away at your bones & teeth etc people!

I have ised it top clean my aluminium boat after it was mored in the ocean on a swing mooring for 12 months and the calcium deposits just foam up and wash off in contact with the acid - but at the same time - thats just what the funes etc getting nt your lungs are doing to your bones and teeth etc.

I can't stress enough to be ever so carefull with it's use if you do choose to use it!

Take heed of all the safety recommendations like gloves and breathing masks filters, eye protection etc etc - just basically treat it like it can kill you or your loved ones / pets and ou'll be OK!

Some of he cream magnesium alloy wheels polishes from the auto spares places might be safer options but a lot more work is all!

Cheers.
