The Best Portable Steam Cleaner for Grout

A good steam cleaner or steam mop will leave your tiled floors, walls and other surfaces spotless, but an exceptional one can get at all the gunk stuck inside the grout, too. This is good news for those of us resigned to painstakingly scraping out all manner of muck and grime accumulating in the gaps over the years, or having to pay up to replace grout altogether. High-pressure steam and the right steam cleaner attachments can work together to remove soap scum, food bits and other nasties otherwise slowly molding between tiles and turning your floors or bathroom walls into toxic wastelands of germs and pathogens.

The low-moisture vapor molecules get right into the highly porous textures of grout, expanding and pushing dirt out, loosened further with the aid of steam cleaner attachments like brass utility brushes, while killing any pathogens and allergens lurking in there. After that, it’s a matter of a little scrubbing and mopping it all off and you’ll be surprised by how much cleaner your grout will be, without needing expensive replacements or excessive and futile elbow grease. That is, as long as you pick the right steam cleaner for the job.

The large 48-ounce water tank allows you enough firepower to continuously blast highly pressurized steam for 40 minutes straight, great for tackling longer stretches of flooring, walls or other surfaces without having to repeatedly stop for refills. The lockable trigger system is also a brilliant design choice, giving us complete control over whether we’re applying intermittent bursts of steam, or a constant stream of it.

Capable of heating up water into low-moisture, high-pressure steam in just under 8 minutes, you can quickly get to work with this portable but heavy-duty cleaner, smooth-rolling caster wheels and an extra-long, 15-foot power cord as well as extension wands making accessing even the highest stretch of your bathroom wall or the narrowest gap of tile between pieces of furniture that much easier.

Color us impressed with how well this quaint little handheld steam cleaner tackles even the toughest of grimy grout.

While the smaller tank capacity – holding about 6.6 ounces in the measuring cup included with the unit – means you have to contend with more frequent refill breaks and shorter steam cleaning times, we’re still fans of this unit, not just for the extremely pocket-friendly price-tag, but also because despite being small, it packs a big punch. An intuitive trigger at your fingertips and grip-handle make holding and using this unit where you need it a simple business. A variety of attachments aside from the grout brush, including a squeegee, angle contractor, flat scraping tool and even a fabric steaming attachment for steam cleaning clothes, linen, duvets and so on, gives you a versatile but compact, decently priced steam cleaner with an array of possible applications.
