In order to decide the correct product to eradicate this common problem we need to establish all the surfaces to be cleaned.
Urinal type - Enamel or stainless Steel
Floor - Ceramic, concrete, vinyl
Generally the main source of stale smell in gents usually comes from 2 main areas, drains and floor. Ordinary disinfectant, even bleach is not enough. Particularly linked to high beer sales, yeasts will build up in the drains, usually slowing down the flow of flush water, which increases the problem. In hard water areas these yeasts combine with water scale to form a hard apparently immovable crust. A dark brown stain on floor tiles under the urinals or tough.
Bowl ReNew is an acid based Toilet de-scaler which immediately dissolves these build ups from enamel urinals and ceramic , tile or concrete floors in just a couple of minutes. This process should be routinely planned once a month to maintain perfectly clean gents toilets. this product is not suitable for stainless steel surfaces or any polished metal.
For stainless steel urinals then a milder acidic product called Stainless is available, but acts much slower and is required to be applied and left for 15 - 20 mins. Generally several applications applications may be required to fully remove very heavy build ups. Used regularly, weekly, this problem can be maintained, odour free.
To compliment either of theses products use Obsession, a perfumed daily disinfectant for all round daily washroom cleaning. This product leaves enamel surfaces and taps sparkling, more imposrtantly its powerful yet fresh perfume soaks into flors for long lasting freshness.
