been cleaning my first tiles yesterday
around 20sqm, asked for 70, took me a bit over hour, sure could be done in around 40min but that was my first time
asked for 70 and got it with no problem, sprayed with solutions sts (had a sample bottle), scrubed it with tm4, extracted with the wand and glide on it, and then quick clean with magic sponge around the edges and some bits of remining dirt.
it was on the top of upholstery clean job
