Pink's do not use chemical cleaners for several reasons:

A large number of chemicals used in today's household cleaning products started out as surplus industrial chemicals left over from the war in 1945. The drive for instant cleaning solutions for busy families has increased the use of these strong chemicals in household products. However, no consideration was given to the long term effects of use of such chemicals in our daily lives.

Health Problems
In the last decade, the incidence of asthma in men has increased 29%, and in women that rise is 82% due in part to larger fat reserves in the female body, where toxins are stored, and also to longer exposure to chemicals because women carry out more household tasks involving cleaning materials.

The Effects on Children

Children are especially at risk from absorption of harmful chemicals used in cleaning products. Small children rub their toys over carpets and floors cleaned with toxic products and put them in their mouths. A child's respiratory rate is three times that of an adult, thus breathing in more of the chemicals.

The main culprits are aerosols, which discharge cleaning products into the air. The maxim 'if you can't eat it, don't breathe it …' is certainly appropriate, and you should consider using an alternative to any product that demands use only in a ventilated space.

Safe Alternatives

Vinegar and hot water for cleaning greasy surfaces, including glassware and windows.
Soda crystals - also known as washing soda can be used to clean work surfaces, and left overnight, will clean the sink.
Bicarbonate of soda makes an excellent paste when mixed with water to clean the inside of an oven, and the cooker top.
Lemon juice is a serviceable toilet cleaner, it smells fresh, and is totally free of any airborne toxins.

Borax is soluble in water and acts as a mildew inhibitor and a deodorant, again with no chemical side effects

Beeswax is a natural product so instead of buying an aerosol containing it, use the real thing for a chemical free clean.

The scientific evidence seems to be both good and bad. We are using too many household chemicals that are causing harmful deposits of poisons in our bodies, which are leading to increases in disease. The good news is that the old tried and trusted cleaning methods may be set to make a return because even though they may be more difficult to obtain, and require a certain amount of physical effort to use, in the long run they are far better for us, and most important, for our children.
