Wee-away™ has been developed using selective strains of naturally occurring microbes, ‘friendly bacteria’. These bacteria feed on the uric crystals and other organic matter to remove all traces of urine altogether. This not only prevents the foul smell returning but can also prevent pets re-marking their territory. The formula has been specifically designed to clean mess from pets such as vomit, urine and faeces, completely ridding your home of odours and discouraging pets from repeat marking. Bleach and Ammonia free formula. Pet safe - no need to exclude your pet from the treated area. Safe for use on carpets, upholstery, sofas, bedding, curtains, clothing and any other water-safe surfaces. Rapidly neutralises and eliminates odours. A proportion of all sales goes directly to the RSPCA. Bottles are supplied with 1 x long hose trigger for ease of application.
