I’ve been thinking lately that most Truckmount breakdowns are related to heat issues. Got me to thinking, can carpets be cleaned “effectively” without hot water extraction?
Yes, carpets can be cleaned with cold water. Effectively? Not as effectively as with hot water. Hot water has a tendency to rinse better, emulsify oil and provide some soaps and chemicals with an additional reaction to boost performance. Truckmounts are designed for hot water extraction. Using cold water can be used to clean but extraction would be much more difficult. Let me explain the best I can. When we clean with hot water, the water coming coming out of the jets are partially atomized. This atomization process helps our vacuum systems to extract and recover more efficiently. Cold water actually slows down the efficiency of the vacuum system for a few reasons. Cold water tends to create more foam during turbulence than hot water would. As hot water will keep the soap from foaming inside the vacuum hose more so than cold water. Increasing soap to make up for the lack of hot water would not be such a viable solution in this application. If cold water were to be used in a truckmount the flow rate and/or the psi of the solution would need to be lowered for a standard truckmount. Also, allot of the chemicals we use for carpet cleaning, require, or are suggested to be used with warm or hot water as a catalyst. this improves the chemicals efficiency. Hydrogen peroxide and reducing agents are an example of this. They work better with the addition of heat.I’ve been thinking lately that most Truckmount breakdowns are related to heat issues.
