There are a few differences because Universal is an excellent ‘all-purpose cleaner’ that is suitable for bathroom cleaning, and Sanitary Cleaner is specifically designed for the job. Firstly, Universal cleaner has a concentrated formula, which is economical as well as eco-friendly: One £15 litre bottle makes up to 200 trigger spray 500ml bottles diluted, costing only 7.5p per bottle. It’s suitable for all general household cleaning – tiles, hard surfaces and plastics as well as your car, wheelie bins, patio, artificial grass, pet carriers, outdoor furniture – and of course, bathroom. However, Universal cleaner is not recommended for complex and sensitive surfaces such as marble and bluestone. In contrast, Sanitary cleaner has a ‘ready to use’ formula. It is designed specifically for cleaning bathrooms and so has a lower pH, extra odour control and a higher number of probiotics. It is also safe for use on sensitive surfaces, although (as with any new products) we do recommend a discreet patch test if you have unusual or very sensitive surfaces. Both products are free from harsh chemicals and safe for use around pets.
