Does Steam Cleaning Damage Grout?

Well, a lot of people use tiles on the kitchen and washroom flooring of their houses. Steam cleaning is an incredible method to clean the germs, stains, and chemicals on the floor and grout.

But does steam cleaning damage grout? The answer is NO, steam cleaning does not damage the grout at any point until it is already damaged or gets affected by some chemical. Let’s have a look to get an idea about it.

Does It Really Steam Cleaning Not Damage Grout?

The misconception about grout being affected by steam cleaning is caused by online reviews or wrong information or may be due to people having very little information about steam cleaning.

But the fact is, steam cleaning does not damage grout. Steam cleaning is referred to as one of the most proficient methods to clean the grout.

Steam cleaning uses plain water vapors which may not be able to affect any hard thing such as grout in any way, until or unless it gets interacted with some chemical agents which may deteriorate the grout.

The steam cleaner is an automated machine used for deep-cleaning purposes at home. Therefore, in steam cleaning through a steam cleaner, water is heated at a temperature more than the boiling point of water (150-212 degrees Fahrenheit) and converted to steam which escapes out of the nozzle in the form of a steam blast.

Why Cracks and Crumbles Formed in Grout?

There are different reasons behind the formation of cracks and crumbles in the grout but the major factors are mentioned below:

Inappropriate Sealing of Grout

If the grout is not sealed in an appropriate manner, it would break down the tiling because of dust accumulation in it and destroy the whole appearance of the house.

Water Saturation

Always use a pre-mixed grout for a defined settling of two tiles. If the grout suffers a lot of water saturation, the lining of the grout may affect badly.

Because the water seeps through the grout and seeping of water molecules may disrupt the grout structure, hence resulting in the breakdown of the grout.

Inefficient Filling of Grout

If the grout between the tiles is not filled in a concise and well-defined manner, there would be empty spaces among the tiles that may lead to the accumulation of germs and debris in the grout.
