A shocking time lapse video showing how our industry has unscrupulous suppliers who claim to have approved products which have been tested when in fact, their cleaning chemicals are corroding and damaging aircraft. This time lapse video clearly shows wow aluminium foil is completely dissolved in 6 hours! The excuse that ‘it is the problem of the chemical manufacturer as they say it is approved’ is not valid, as a responsible company, it is also your duty to double check. This is commonplace in our industry and must be stopped as it is putting people’s lives at risk.
