Toilet Cleaner - Formaldehyde
Todays Telegraph has an article concerning an incident aboard a BAe 146 & its crew becoming affected by fumes from the toilets. It would appear that formaldehyde was used to clean the toilets while the a/c was on maintenance. So is this a substance commonly used for a deep clean while on maintenance or is this chemical contained in the normal blue fluid we see every day?
If an engineer would be so kind to provide us with a detailed explanation. Thanks in advance.
