When it comes to tile cleaning we only use stone tech products, which is a superior tile cleaning product. So let's talk tile cleaning, we pretreat the condition with an alkaline and let set for 10-15 minutes. Then we scrub all the grout lines and steam clean them at 1000 psi with our powerful truck mount. Next we hand dry. Prior to putting on a seal, we double check our work and if we are not 100% satisfied we completely redo the process again with a stone tech acid. When your tile looks its best, we then seal it, which should last for at least 2 years if maintained per our instructions. If you need your tile & grout cleaned, give us a call today!
