Safe cleaning for a travertine pool deck
Travertine is a porous material, which means an aggressive approach is not the way to go. The most prudent course of action is a gentle and consistent routine that relies on the product label rather than force. To clean safely, begin by dry sweeping, then turn to a pH-neutral cleaner suited to natural stone along with a soft brush and a good rinse. Keep in mind that acids, heavy pressure washing or abrasive pads can etch the surface and do damage to the joints.
The proper sequence
1. Clear away debris. Sweep or blow off any sand, grit or leaves first; this will keep you from scratching the deck as you work. 2. Take a look around. Check for white mineral deposits, dark buildup in the grout, algae film or other stains. 3. Select an appropriate cleaner. Stick to something made for natural stone and heed the manufacturer’s instructions. 4. Be gentle with it. Work in small sections using a microfiber mop or a soft-bristle scrub brush. 5. Rinse thoroughly. You want to be sure no residue is left behind to form a film or draw in more dirt. 6. Allow it to dry. Once the deck is dry you will be able to spot any uneven areas or stains that have been missed.
Things to steer clear of
While travertine pavers and tiles are elegant, they are more susceptible to damage than some hardscape. Do not use vinegar, bleach, ammonia or peroxide unless the stone’s instructions explicitly say so. The same goes for all-purpose cleaners of unknown origin. Avoid steel wool or stiff brushes, and do not run a power washer right up against the grout lines or surface. Standing water on the deck should also be avoided. When in doubt about a new cleaner, put it to the test in a hidden spot to see if it causes dulling or discoloration.
Dealing with grime and stains
If there is an isolated stain, do not soak the entire patio; spot-clean the area instead. Employ the mildest method possible for the job at hand. Should the mark persist, you can repeat the process before trying anything stronger that is approved for natural stone. With mildew or slippery algae, act quickly. On a textured deck these tend to get into the pores and grout where a soft brush and careful rinse are more effective than brute force.
For recurring white crusting, sealer failure or stubborn dark stains, the problem may run deeper. A stone-care professional can determine if resealing or re-grouting is called for.
Is sealing necessary?
In many cases, yes, provided your stone manufacturer or a pro gives the nod for your particular installation. It will help with staining but will not remedy loose stones, cracks or water intrusion. Make certain the deck is completely dry and read the sealer label before proceeding.
Time to call in a pro?
There are times when it is best to leave it to an expert. This includes if you notice failing grout, loose pavers, or deep stains that will not budge. The same applies to large patches of algae, widespread dulling, or if you find repeated white residue after a rinse.
Safety is paramount when working around the pool. Turn off the pump to get to the skimmer baskets and don PPE. Never put a hand in operating suction equipment. And if you suspect an electrical fault in the vicinity of the pool, put down the tools and contact a qualified professional.
