RTC Grouting Sponges
The Original and STILL the Best Grouting Sponge on the Market
Don't be fooled by look-a-likes and knock-offs at your local big box tool store...
RTC Products Grouting Sponges are the original formula sponges that were brought overseas from Greece many years ago. The formula has remained the same- Buy the best at the best price!
Why it's better:
The HYDRA SPONGE is the preferred washing sponge by professionals. They are more durable than any other polyester sponge and more cost saving than any natural sponge. They wash out clean, dry soft, and are always uniform in size and quality.
