Why cold water instead of hot water for rinsing a jacuzzi tub?

[ldv1452]

This may seem like an odd forum for this question but I couldn't find an answer anywhere else. Why is it always recommended to rinse the dishwashing liquid and bleach with cold water, rather than hot, when cleaning a jacuzzi tub. Doesn't hot water dissolve and rinse better? My guess is energy saving reasons, but I am curious if there is some scientific advantage to using cold water.

I'm not sure specifically about the jacuzzi situation but in Nursing School we were taught that, when cleaning anything with body fluids you rinse with cold water first and then hot water. Rationale being that higher temperatures can denature proteins and such and may cause them to adhere to surfaces with greater strength (think how fried eggs will stick to a pan). So you rinse with cold and follow up with hot.

Empirically I've found the above method to work very well for cleaning the blender or shaker bottle when I drink protein shakes though I'm not sure how relevant this situation is to the above or your own.

Just a guess: warm or hot water can force water-hardness deposits and buildup over time. Using cold water will help avoid this. Also, if you are using bleach, I imagine any splashing from cold water might be safer than from hot water.

Other guess: bleach and hot water means more chlorine in the air.

Fourth guess. Proteins + bleach = volatile chloramines. More volatile when hot.

If you have ever tried to rinse any foaming agent with hot water you will instantly understand.

Try it in a sink with a spot of ordinary washing up liquid, generate some foam then try to rinse away with hot or cold. The cold 'kills' the suds; the hot enhances them.

I think this and the other explanations here all point the same way. Pretty unusual in life which is normally about the balance between conflicting requirements.
