We seal our concrete tables so they can be used and enjoyed for many years. We have tested various products such as red wine and tabasco sauce so we can provide you with proven recommendations. Vinegar based products should be removed IMMEDIATELY as the acid works quickly through the sealant. As with anything, if something is split, it should be removed as soon as possible with warm water, a mild detergent and a cloth. If you find a stain has not been removed and left for over 4 hours, we recommend you use a bleach solution directly onto the area for a couple of minutes and then removed with a sponge. Please note, after cleaning, light stains generally soak into the concrete as it is porous and will varnish over time. If you apply a harsher cleaning method, this may remove the sealant for future protection so we do not recommend. If you find this has happened, please let us know and we can discuss resealing your concrete table for you.
