Best Uses for Super Heated Steam Cleaning

The super-heated steam quickly removes algae, kills moss and other unsightly stains or graffiti reducing the need for harsh chemical cleaners.

Cleaning stone and masonry with super heated steam allows the surface to dry quickly and avoids the use of high pressure jetting where water droplets are forced and driven in to any porous surface which can become frozen in harsh winter periods causing spalling of brick masonry or stone in later years. It is also used to remove some paints from historic building surfaces, render, brick, masonry and architectural stone.

We believe super heated steam cleaning systems for building cleaning are the ideal cost effective solution. APT have recently launched a new version of the low pressure high steam cleaning system, we call it simply Hot Box. It was designed by our site operatives and engineers and they believe it has all the attributes of the doff stone cleaning system and Torik type cleaning but with added higher steam values, extra control allowing more stable consistent delivery of steam over longer hose runs.

It certainly cuts down on our labour service costs and therefore it is a more effective option for our clients.
