</p> <b>How much heat can it take?</b> <p>We recommend using it temperatures below 350 degrees Fahrenheit (177 degree Celsius) to protect the pad for long-term use.</p> <b>Should I use a cleaner?</b> <p>Depending on how dirty your surface it, a cleaning fluid can definitely help out in preventing the pad from getting too full of grime. We recommend 2 parts water or club soda to 1-part vinegar as a cheap and safe option (compared to using synthetic chemicals).</p> <b>Can I use this on ceramic/porcelain bowls?</b> <p>You can, but you have to be very careful to not scrub too hard and only if you are working to get off long-term, baked on grime (don’t use these for regular cleanings). We recommend heating up the bowl, using cleaning fluid, like the kind described above, and gentle strokes to slowly remove buildup.</p> <b>Lifetime Money-Back Satisfaction Guarantee!</b> <p>If you aren’t completely satisfied with your order, simply reach out to us through the Amazon messaging service and we will respond within 24 hours to make it right even on the weekends.
